In the context of the COVID-19 pandemic, which disrupted face-to-face teaching globally, educational institutions in Bangladesh adopted online instruction as the best available alternative. Since teachers and students were not quite familiar with remote teaching, it was deemed necessary to gauge their level of preparedness for online instruction. This study investigated the perceptions of teachers and students of public universities, and examined their views of online pedagogy, assessment and the major challenges faced. Data were collected from 158 teachers and 1468 students through survey questionnaires and Focus Group Discussions. Results indicate that participants had favourable attitudes towards online classes, but they expressed concern for students who they thought were marginalized due to lack of digital devices and poor internet connectivity. Inadequate teacher preparation, lack of familiarity with online pedagogy, limited know-how of online assessment and issues of affordability and equity were reported to be the major threats. Initial insights highlight the need for supporting the disadvantaged students as well as training teachers to employ appropriate tools and techniques for teaching and assessing online.

Tropical cyclones, one of the most extreme and destructive meteorological incidents, cause extensive damage to lives and livelihoods worldwide. This study utilized remotely sensed data along with multi-criteria decision-making, geospatial techniques, and major cyclonic events Aila, Amphan, and Yaas to identify the changes in the vulnerability of cyclone-induced floods in the 19 community development blocks of Indian Sundarbans in the years 2009–2010, 2020–2021, and 2021–2022 (the post-cyclonic timespan). The Sundarbans are a distinctive bioclimatic region located in a characteristic geographical setting along the West Bengal and Bangladesh coasts. In this area, several cyclonic storms had an impact between 2009 and 2022. Using the variables NDVI, MNDWI, NDMI, NDBI, BSI, and NDTI, Landsat 8 Operational Land Imager, Thermal Infrared Sensor, Resourcesat LISS-III, and AWiFS data were primarily utilized to map the cyclonic flood-effective zones in the research area. The findings indicated that the coastline, which was most impacted by tropical storms, has significant physical susceptibility to floods, as determined by the AHP-weighted overlay analysis. Significant positive relationships (p < 0.05, n = 19 administrative units) were observed between mangrove damage, NDFI, and physical flood susceptibility indicators. Mangrove damage increased with an increase in the flood index, and vice versa. To mitigate the consequences and impacts of the vulnerability of cyclonic events, subsequent flood occurrences, and mangrove damage in the Sundarbans, a ground-level implementation of disaster management plans proposed by the associated state government, integrated measures of cyclone forecasting, mangrove plantation, coastal conservation, flood preparedness, mitigation, and management by the Sundarban Development Board are appreciably recommended.

In this work, we have investigated text readability in Bangla language. Text readability is an indicator of the suitability of a given document with respect to a target reader group. Therefore, text readability has huge impact on educational content preparation. The advances in the field of natural language processing have enabled the automatic identification of reading difficulty of texts and contributed in the design and development of suitable educational materials. In spite of the fact that, Bangla is one of the major languages in India and the official language of Bangladesh, the research of text readability in Bangla is still in its nascent stage. In this paper, we have presented computational models to determine the readability of Bangla text documents based on syntactic properties. Since Bangla is a digital resource poor language, therefore, we were required to develop a novel dataset suitable for automatic identification of text properties. Our initial experiments have shown that existing English readability metrics are inapplicable for Bangla. Accordingly, we have proceeded towards new models for analyzing text readability in Bangla. We have considered language specific syntactic features of Bangla text in this work. We have identified major structural contributors responsible for text comprehensibility and subsequently developed readability models for Bangla texts. We have used different machine-learning methods such as regression, support vector machines (SVM) and support vector regression (SVR) to achieve our aim. The performance of the individual models has been compared against one another. We have conducted detailed user survey for data preparation, identification of important structural parameters of texts and validation of our proposed models. The work posses further implications in the field of educational research and in matching text to readers.

Purpose: This study aims to explore whether socio-economic factors determine the level of menstrual knowledge and perceptions of schoolgirls in Bangladesh. The aim of this study is to understand how knowledge and perceptions vary with variations in the different socio-economic factors in a schoolgirl's life such as place of residence, religion, age, grade, parents' education, parents' occupation, family income and even family size. Design/methodology/approach: Data were collected from four schools (two in urban areas and two in rural areas). A total of 450 schoolgirls from grades V–X were interviewed to examine how knowledge and perceptions varied with different socio-economic aspects. Multiple logistic regression models were used to measure the associations between various socio-economic variables and perceptions of and knowledge about menstruation. Findings: Respondents from urban areas were 4.75 times more likely and those 14–16 years old were two times more likely to report higher levels of knowledge about menstruation compared to their counterparts. Based on the father's occupation, respondents whose father was engaged in a professional occupation were 1.983 times more likely to have a higher level of knowledge on menstruation compared to those whose fathers were in an unskilled profession. Similarly, the odds of positive perceptions on menstruation were 1.456 and 1.987 times higher, respectively, among respondents living in urban areas and those 14–16 years old, compared to their counterparts. Originality/value: This study provides evidence that different socio-economic and even demographic factors are important in the development of menstrual knowledge and perceptions. Policy formulation and development actions related to adolescent girls' physical and reproductive health development need to consider these factors in Bangladesh and in other developing countries, where poor knowledge and perception related to menstruation are hindering girls' mental and physical development. This is expected that better knowledge and perception will facilitate girls' right to have better health and social lives. [ABSTRACT FROM AUTHOR]

Developing an Optical Character Recognition (OCR) system for handwritten texts is a challenging research problem. Handwritten text can be largely different even for the same piece of text since the writing style differs from person to person. On the other hand, for many regional languages, unavailability of datasets having a large quantity of varied images is a hindrance for the research advancements. This is especially true for Bangla, which is the most widely spoken language of Bangladesh and the second most widely spoken language of India. Only a few works have been proposed for the generation of handwritten Bangla basic characters and almost none related to the generation of handwritten Bangla compound characters. To this end, in this work, a method for the generation of synthetic handwritten Bangla compound characters is proposed to alleviate this data scarcity. A generative adversarial network (GAN) based model is developed for this purpose taking inspiration from the recent Auxiliary Classifier GAN (AC-GAN) model. A novel dataset partitioning scheme is also developed for handwritten character related tasks to improve the performance of the model. The quality of generated samples is evaluated in terms of the Fréchet Inception Distance (FID) metric. It is observed that the present model performs better in comparison to the basic AC-GAN architecture and also in comparison with some present GAN architectures. The sample dataset generated as a part of this work is publicly available at https://github.com/hachiro-2001/Bengali_Compound_Characters. [ABSTRACT FROM AUTHOR]

There is increasing evidence of the post-COVID-19 suffering and decreased quality of life in the COVID-19 patients. This study aimed to assess the quality of life and associated factors of COVID-19 patients at one month after discharge from the hospital. This was a cross-sectional study that was conducted at the post-covid clinic of Dhaka Medical College Hospital (DMCH) where RT–PCR-confirmed adult COVID-19 recovered patients were enrolled one month after discharge from the same hospital. They were consecutively selected from January 01 to May 30. A pretested semi-structured questionnaire was used for the data collection for clinical variables. The generic multi-attributable utility instrument EQ-5D-5L was used for assessing health-related quality of life (HRQoL). A total of 563 patients were enrolled in the study. The patients had a mean age with standard deviation (±SD) of 51.18 (±13.49) years and 55.95% were male. The mean (SD) EQ-5D-5L index score and EQ-VAS scores were 0.78 (±0.19) and 70.26 (±11.13), respectively. Overall, 45.77%, 50.99%, 52.79%, 55.14% and 62.16% had problems (slight to extreme) in the mobility, self-care, usual activities, pain/discomfort and anxiety/depression dimensions, respectively. Patients aged ≥60 years had significant problem in mobility (odds ratio [OR] 3.24, 95% confidence interval [CI]: 1.07–9.77). Female participants were 5.50 times (95% CI: 2.22–13.62) more likely to have problems in their usual activities. In comparison to urban area, living in a peri-urban setting was significantly associated with problems in mobility (OR 1.89, 95% CI: 1.13–3.20), pain/discomfort (OR 1.82, 95% CI: 1.04–3.12) and anxiety/depression (OR 2.16, 95% CI: 1.22–3.84). Comorbid patients were 1.75 times (95% CI: 1.07–2.85) more likely to report problems in the pain/discomfort dimension. Presence of symptom(s) was associated with problems in self-care (OR 3.27, 95%CI: 1.31–8.18), usual-activity (OR 3.08, 95%CI: 1.21–7.87), pain/discomfort dimensions (OR 2.75, 95%CI: 1.09–6.96) and anxiety/depression (OR 3.35, 95%CI: 1.35–8.30). Specific management strategies should be planned to address the factors associated with low health-related quality of life in post-acute care of COVID-19 patients. [ABSTRACT FROM AUTHOR]

The southwestern coastal part of Bangladesh is highly vulnerable to different kinds of disasters due to the changing climatic conditions. With the lenses of rural communities here an approach to examine how were the different disasters experiences, what lesson they learnt and what are their present disaster associated problems and stakeholder's networks they rely on to enhance their resilience. Qualitative data were collected through participatory rapid rural appraisal (100–150 persons), field observation, 12 focus group discussions (25–40 people/FGD), and key informant interviews (25 people) in four southwestern coastal districts and nine coastal villages of Bangladesh. Results showed that since long back to date drinking water crisis, poor roads, poverty, poor sanitation, and health problems are the main identified disaster-associated problems. After learning lessons from previous disaster experiences, the community people have improved and changed their practices mainly by storing emergency foods, house construction, and increasing disaster awareness. However, the coastal communities are combating with the problems that have both direct and indirect association with poor infrastructures. Therefore, the coastal communities urge and sketched for a better stakeholders' supports and networks to minimize their problems and thus to enhance communities' disaster resilience.

Background: Much scholarly debate has centered on Bangladesh's family planning program (FPP) in lowering the country's fertility rate. This study aimed to investigate the prevalence of using modern and traditional contraceptive methods and to determine the factors that explain the contraceptive methods use. Methods: The study used data from the 2017–18 Bangladesh Demographic and Health Survey (BDHS), which included 11,452 (weighted) women aged 15–49 years in the analysis. Multilevel multinomial logistic regression was used to identify the factors associated with the contraceptive method use. Results: The prevalence of using modern contraceptive methods was 72.16%, while 14.58% of women used traditional methods in Bangladesh. In comparison to women in the 15–24 years age group, older women (35–49 years) were more unwilling to use modern contraceptive methods (RRR: 0.28, 95% CI: 0.21–0.37). Women who had at least a living child were more likely to use both traditional and modern contraceptive methods (RRR: 4.37, 95% CI: 3.12–6.11). Similarly, given birth in the previous 5 years influenced women 2.41 times more to use modern method compared to those who had not given birth (RRR: 2.41, 95% CI: 1.65–3.52). Husbands'/partners' decision for using/not using contraception were positively associated with the use of both traditional (RRR: 4.49, 95% CI: 3.04–6.63) and modern methods (RRR: 3.01, 95% CI: 2.15–4.17) rather than using no method. This study suggests rural participants were 21% less likely to utilize modern methods than urban participants (RRR: 0.79, 95% CI: 0.67–0.94). Conclusion: Bangladesh remains a focus for contraceptive use, as it is one of the most populous countries in South Asia. To lower the fertility rate, policymakers may design interventions to improve awareness especially targeting uneducated, and rural reproductive women in Bangladesh. The study also highlights the importance of male partners' decision-making regarding women's contraceptive use. [ABSTRACT FROM AUTHOR]

Background & objectives: Visceral Leishmaniasis (VL) or Kala-azar is a deadly disease putting 350 million people from 88 countries at risk. In Bangladesh, 45 districts are endemic. Zinc is an essential trace element and its relevance for proper functioning of the entire immune system is already well documented. Though low serum zinc levels have been reported in many parasitic diseases, limited information is available regarding zinc status in human leishmaniasis. This study was conducted to evaluate the zinc level in endemic and non-endemic population of kalaazar. Methods: This cross-sectional study was conducted to assess the serum zinc concentrations in kala-azar endemic and non-endemic population of 06 to 60 years of age range during the period of July 2014 to June 2015.Venous blood was collected from 92 subjects to estimate serum zinc concentrations. Results: Mean Serum zinc levels were found 63.66 microgm/dl in kala-azar patients of endemic area, 69.44 microgm/dl in kala-azar endemic populations and77.34 microgm/dl in non-endemic populations. Conclusion: The average serum zinc concentrations is lower in populations of kala-azar endemic zone compared to populations from kala-azar nonendemic zone. It was also found that kala-azar patient had lower zinc concentrations compared to non-kala-azar patients. There may have potential association of low zinc level and occurrence of kala-azar.

Background: The alarming rise in multi-drug resistant (MDR) zoonotic pathogens, including Campylobacter spp., has been threatening the health sector globally. In Bangladesh, despite rapid growth in poultry sector little is known about the potential risks of zoonotic pathogens in homestead duck flocks. The aim of this study was to understand the occurrence, species diversity, and multi-drug resistance in Campylobacter spp., and identify the associated risk factors in duck farms in Bangladesh.Methods: The study involved 20 duck farms at 6 sub-districts of Mymensingh, Bangladesh. Monthly occurrence of Campylobacter spp. in potential sources at the farms during February-September, 2018, was detected by culture and PCR-based methods. Campylobacter isolates were examined for resistance to different antimicrobials. Risk factors, concerning climatic and environmental disposition, farm management, and anthropogenic practices, of Campylobacter infection were estimated by participatory epidemiological tools.Results: Occurrence of Campylobacter spp. was detected in overall 36.90% (155/420) samples, more frequently in drinking water (60%, 30/50), followed by cloacal swab (37.50%, 75/200), egg surface swab (35%, 35/100) and soil of the duck resting places (30%, 15/50) but was not detected in feed samples (n = 20). PCR assays distinguished the majority (61.30%, 95/155) of the isolates as C. coli, while the rest (38.70%, 60/155) were C. jejuni. Notably, 41.7% (25/60) and 31.6% (30/95) strains of C. jejuni and C. coli, respectively, were observed to be MDR. The dynamics of Campylobacter spp., distinctly showing higher abundance during summer and late-monsoon, correlated significantly with temperature, humidity, and rainfall, while sunshine hours had a negative influence. Anthropogenic management-related factors, including, inadequate hygiene practices, use of untreated river water, wet duck shed, flock age (1-6 months), and unscrupulous use of antimicrobials were identified to enhance the risk of MDR Campylobacter infection.Conclusion: The present study clearly demonstrates that duck farms contribute to the enhanced occurrence and spread of potentially pathogenic and MDR C. coli and C. jejuni strains and the bacterial dynamics are governed by a combined interaction of environmental and anthropogenic factors. A long-term holistic research at the environment-animal-human interface would be integral to divulge health risk reduction approaches tackling the spread of Campylobacter spp. from duck farms.

During the brief coronavirus-induced hiatus in March and April 2020, educational institutions in Bangladesh including public universities began preparations for online classes. By the end of June, almost all private universities and a few public universities had started online classes with limited or no preparation, which was met with appreciation as well as censure from different stakeholders. Against this backdrop, this study was conducted with a view to examining the online teaching-learning scenario at Bangladeshi public universities from the perspective of one important stakeholder, the students, with a specific focus on the challenges they faced with this new mode of instruction. Suggestions were also sought from them regarding how the barriers to online instruction could be overcome. Data were collected from 26 students of English Departments of 11 public universities through semi-structured interviews. The major challenges reported include issues of access and equity, inadequate logistic support and poor infrastructure. Concerns related to curriculum, pedagogy, assessment and psychological issues were also highlighted. In addition, lack of prior experience and inadequate training were identified as serious obstacles. Major suggestions from the participants include ensuring access and equity, providing training opportunities and digital devices to students, and engaging in curriculum and assessment reforms.

The paper reports an evaluation of the effectiveness of fish polyculture as an adaptation strategy against environmental change in the southwest coastal region of Bangladesh. The research applies descriptive statistics, Cobb–Douglas production function model, and priority index. Simple random and convenient sampling techniques have been used to select sample and study area, respectively. The study shows that fish polyculture is economically viable and profitable. Besides, pond size, labour, and fertiliser have a significantly positive association (p < 0.05) with fish production. Virus-related mortality, salinity level, access to loans, and shrimp seedling prices are notable constraints on the fish polyculture system. [ABSTRACT FROM AUTHOR]

Background: Understanding potential risks of multi-drug resistant (MDR) pathogens from the booming poultry sector is a crucial public health concern. Campylobacter spp. are among the most important zoonotic pathogens associated with MDR infections in poultry and human. This study systematically examined potential risks and associated socio-environmental factors of MDR Campylobacter spp. in poultry farms and live bird markets (LBMs) of Bangladesh.Methods: Microbial culture and PCR-based methods were applied to examine the occurrence and MDR patterns of Campylobacter spp. in potential sources (n = 224) at 7 hatcheries, 9 broiler farms and 4 LBMs in three sub-districts. Antimicrobial residues in broiler meat and liver samples (n = 50) were detected by advanced chromatographic techniques. A questionnaire based cross-sectional survey was conducted on socio-environmental factors.Results: Overall, 32% (71/ 224) samples were found contaminated with Campylobacter spp. In poultry farms, Campylobacter spp. was primarily found in cloacal swab (21/49, 43%), followed by drinking water (8/24, 33%), and meat (8/28, 29%) samples of broilers. Remarkably, at LBMs, Campylobacter spp. was detected in higher prevalence (p < 0.05) in broiler meat (14/26, 54%), which could be related (p < 0.01) to bacterial contamination of drinking water (11/21, 52%) and floor (9/21, 43%). Campylobacter isolates, one from each of 71 positive samples, were differentiated into Campylobacter jejuni (66%) and Campylobacter coli (34%). Alarmingly, 49 and 42% strains of C. jejuni and C. coli, respectively, were observed as MDR, i.e., resistant to three or more antimicrobials, including, tetracycline, amoxicillin, streptomycin, fluoroquinolones, and macrolides. Residual antimicrobials (oxytetracycline, ciprofloxacin and enrofloxacin) were detected in majority of broiler liver (79%) and meat (62%) samples, among which 33 and 19%, respectively, had concentration above acceptable limit. Inadequate personal and environmental hygiene, unscrupulously use of antimicrobials, improper waste disposal, and lack of health surveillance were distinguishable risk factors, with local diversity and compound influences on MDR pathogens.Conclusion: Potential contamination sources and anthropogenic factors associated with the alarming occurrence of MDR Campylobacter, noted in this study, would aid in developing interventions to minimize the increasing risks of poultry-associated MDR pathogens under 'One Health' banner that includes poultry, human and environment perspectives.

Extreme weather events (EWEs) such as hailstorms are an increasing threat to agriculture worldwide. To develop successful and efficient hailstorm risk management policies, it is important to understand the composition of farmers' hailstorm risk perceptions. This study aims to identify the determinants of these risk perceptions. This is done by collecting pertinent information on the perceptions of risk, farm traits, adaptive capacity, and various other personal characteristics from farmers' households in hailstorm-oriented areas of northern Bangladesh. By analyzing the explanatory power of various risk factors using the binary logistic regression model, this study reveals that the hailstorm risk perceptions of farmers are embodied by subjective risk factors, such as their perceived control of hailstorm risk, and their personal circumstances. Their perceived resources for tackling hailstorm risk are the most significant predictor variable of hailstorm risk perceptions. Marginal and smallholder farmers are very vulnerable and perceive more risk than is the case with the medium-holder and large-holder farmers, owing to the lack of a compensation policy after the occurrence of hailstorms. The relevant authorities should pay urgent attention to managing hailstorm risks by developing adequate adaptive capacity among farmers in northern Bangladesh. [ABSTRACT FROM AUTHOR]

Increasing the feasibility of easy loan repayment is one of the objectives of providing microcredits for income generating activities requiring relatively small loans in the developing countries. However, evidence in the developing countries suggests that microcredits are often used by households for non-income generating expenditures needed to deal with shocks such as health shocks. Health shocks in particular have severe financial implications due to the absence of health insurance programs in the developing countries and also because they reduce income generating capabilities. The objective of this paper is to examine, using a survey data from Bangladesh, whether there is an association between the health shocks and the loan repayments performance of the borrowers of microfinance institutions. When issues involving mixed distribution of the outcome variable and endogeneity of health shocks are taken care of with IV Tobit and Two-part models, the results show that the health shocks lower both the probability and the amount of repayments. In addition, since a significant portion of the households in Bangladesh represents migrant households, this hints at important policy implications. [ABSTRACT FROM AUTHOR]

This paper examines the effectiveness of crab culture as an adaptation strategy against salinity intrusion in the south-west region of Bangladesh. The research uses descriptive statistics, such as mean, standard deviation, benefit-cost analysis, Cobb-Douglas production function, and total barrier index to show the socio-demographic information of the respondents and profitability, efficiency, and returns to scale along with barriers to crab culture. Simple random sampling has been used to select the sample from the study area. The result from benefit-cost analysis shows that crab production is economically viable and profitable. The estimated results from the Cobb-Douglas production function model indicate the positive influence of crab feed and crab seed on total yield of crab production. There are increasing returns to scale in crab production system where there is still scope to increase productivity of crab production. A few barriers to crab production have been identified. High feed cost and lack of credit are the top barriers to crab culture. [ABSTRACT FROM AUTHOR]

Background: Fetal nutritional insults may alter the later metabolic phenotype. We hypothesized that early timing of prenatal food supplementation and multiple micronutrient supplementation (MMS) would favourably influence childhood metabolic phenotype.Methods: Pregnant women recruited 1 January to 31 December 2002 in Matlab, Bangladesh, were randomized into supplementation with capsules of either 30 mg of iron and 400 μg of folic acid, 60 mg of iron and 400 μg of folic acid, or MMS containing a daily allowance of 15 micronutrients, and randomized to food supplementation (608 kcal) either with early invitation (9 weeks' gestation) or usual invitation (at 20 weeks). Their children (n = 1667) were followed up at 4.5 years with assessment of biomarkers of lipid and glucose metabolism, inflammation and oxidative stress.Results: Children in the group with early timing of food supplementation had lower cholesterol (difference -0.079 mmol/l, 95% confidence interval (CI) -0.156; -0.003), low-density lipoprotein (LDL) (difference -0.068 mmol/l, 95% CI -0.126; -0.011) and ApoB levels (difference -0.017 g/l, 95% CL -0.033; -0.001). MMS supplementation resulted in lower high-density lipoprotein (HDL) (difference -0.028 mmol/l, 95% CL -0.053; -0.002), lower glucose (difference -0.099 mmol/l, 95% CL -0.179; -0.019) and lower insulin-like growth factor 1 (IGF-1) (difference on log scale -0.141 µg/l, 95% CL -0.254; -0.028) than 60 mg iron and 400 μg folic acid. There were no effects on markers of inflammation or oxidative stress.Conclusions: Findings suggest that in a population where malnutrition is prevalent, nutrition interventions during pregnancy may modify the metabolic phenotype in the young child that could have consequences for later chronic disease risks.

Oxidative stress is suggested as a potential mechanism in impaired foetal growth, smaller birth size and thus subsequently adult chronic diseases. We have investigated associations between oxidative stress in pregnancy and birth anthropometry (weight, height, head and chest circumferences). In the MINIMat-trial (Maternal and Infant Nutrition Interventions, Matlab) in rural Bangladesh, free 8-iso-prostaglandin F2α (lipid peroxidation) was analysed in pregnancy week 14 and 30 and 8-Hydroxy-2 -Deoxyguanosine (DNA oxidation) in week 19. We found that higher levels of lipid peroxidation in early pregnancy were associated with larger infant size (birth length and chest circumference). In late pregnancy, no clear pattern of associations was found. Increasing level of DNA oxidation was associated with lower birth length in girls but no other associations were found. In conclusion, a higher level of lipid peroxidation in early (but not late) pregnancy was associated with a favourable larger birth size suggesting that timing of lipid peroxidation is of importance.

The legal realm translates between litigants’ plain-language claims and efficient solutions. In postcolonial courtrooms, there are also some literal translations between vernaculars and formal legal English. Other translations, less literally, involve putting violence and violation into the language of compromise. Through an ethnographic analysis of two Family Courts in Kolkata and Dhaka where litigants directly present their cases to judges, this article argues that the postcolonial (sexed) body is constructed through such translations, while signifying an excess that cannot be captured by legal categories. Sexual consummation and sexual violence appear particularly resistant to seamless translation, and evoke other registers of compensation. [ABSTRACT FROM PUBLISHER]

Augmentative communication aids are used to assist persons with severe speech and motor disabilities in their natural communication. Motion impaired users operate computer-based communication aids with alternate input methods instead of mouse or keyboard, which makes the communication process slow. A word to sentence generation technique called Compansion was proposed to improve communication rate of augmentative comnmnieation users. In Compansion, a sequence of root words was converted to a grammatically well-formed sentence. To perform the conversion, Compansion required significant linguistic knowledge. This requirement limits applicability of Compansion to languages for which such knowledge do not exist. Moreover, the issues of pre(post)position attachment, morphology synthesis and word ordering need to be addressed to apply Compansion to languages other than English. We propose enhancements to make Compansion work for non-English languages. Based on the proposed enhancements, we have developed a word to sentence generator. The word to sentence generator is used in Sanyog - an augmentative communication system in Bengali, a language spoken primarily in Eastern India and Bangladesh. Evaluation of Sanyog shows that our word to sentence generator helps in increasing communication rate without putting significant physical or cognitive load on users. Development and evaluation of onr word to sentence generator is described in this paper. [ABSTRACT FROM AUTHOR]

This paper enquires into the persistent trade deficit against Bangladesh in India–Bangladesh bilateral trade. For this purpose, the paper examines the extent of trade similarities and complementarities between the two countries with the help of RCA indices and Cosine measures. The results show that Bangladesh exports match with Indian exports and not with Indian imports. The paper also calculates G-L indices to measure the extent of intra-industry trade between the two countries and finds that this trade, albeit small, is growing in importance. The paper then makes an econometric study of the demand for Bangladeshi goods in the Indian market with long run time series data and finds that removal of Indian trade restrictions beyond a certain level stimulates export. While analyzing the trade deficit, the paper observes an inverse relation between exchange rate and trade deficit at the bilateral level and finds remittance-driven misalignment and overvaluation in the taka against the rupee, with the possibility of Dutch disease syndrome. As Bangladesh can draw lessons from the success story of Indonesia in avoiding Dutch disease, the paper studies econometrically the management of foreign exchange earning in Indonesia during the oil boom and finds the necessity for policy-induced adjustment in the exchange rate, which can help the Bangladesh economy to diversify and register better export performance in the future.

Relatively little is known about how environmental and pathological threats to human survival and longevity are perceived by the public. In this study in rural Bangladesh and West Bengal, India, which used individual interviews and focus-group discussions to investigate the changing costs of and motivations for reproduction, respondents were questioned about their perceptions of changes in mortality. The findings show that, while child mortality levels are perceived to have fallen dramatically in recent times, the health and survival prospects of the middle aged and the elderly are seen to have been better in the past. The perceived decline in adult health is attributed to environmental deterioration and lifestyle changes accompanying modernization. This paper explores people's reasons for this unexpected worldview. References to pesticides and chemical fertilizers as causes of death abound in their explanations and are seen to be associated with unhealthy agricultural practices and impiety.

To understand the magnitude of the arsenic calamity in West Bengal, a detailed study spanning 7 years was made in North 24-Parganas, one of the nine arsenic affected districts. Area and population of North 24-Parganas district are 4093.82 sq.km and 7.3 million, respectively. Forty eight thousand and thirty water samples were analyzed from hand tubewells of North 24-Parganas in use for drinking, cooking and 29.2% of the tubewells were found to have arsenic above 50 µg/L, the maximum permissible limit of World Health Organization (WHO) and 52.8% have arsenic above 10 µg/L, WHO recommended value of arsenic in drinking water. Out of the 22 blocks of North 24-Parganas, in 20 blocks arsenic has been found above the maximum permissible limit and so far in 16 blocks people have been identified as suffering from arsenical skin lesions. From the generated data, it is estimated that about 2.0 million and 1.0 million people are drinking arsenic contaminated water above 10 µg/L and 50 µg/L level, respectively in North 24-Parganas alone. So far, in our preliminary study 33,000 people have been examined at random from arsenic affected villages in North 24-Parganas and 2274 people have been registered with arsenical skin lesions. Extrapolation of the available data indicates about 0.1 million people may be suffering from arsenical skin lesions from North 24-Parganas alone. A sum of 21,000 hair, nail, and urine samples analyses from arsenic affected villages show 56%, 80%, and 87% people have arsenic in biological specimen more than normal/toxic (hair) level, respectively. Thus, many may be subclinically affected. Due to use of arsenic contaminated groundwater for agricultural irrigation, rice and vegetable are getting arsenic contaminated. Hence there is an additional arsenic burden from food chain. People from arsenic affected villages are also suffering from arsenical neuropathy. A follow-up study indicates that many of the victims suffering from... [ABSTRACT FROM AUTHOR]

This article promotes a more complete understanding of social change by analyzing spatial patterns of contraceptive use in Bangladesh and the contiguous state of West Bengal in India. Multilevel analyses that control for variations in individual- and household-level correlates show an important role for cross-border influences only in those districts that share a common language across the border. The districts that are positive outliers in contraception hug the Bangladesh-West Bengal border. A map of outliers shows that the positive outliers form a contiguous band in a manner suggestive of a role for contagion. [ABSTRACT FROM AUTHOR]

A cross-sectional survey was conducted in selected districts of Bangladesh to estimate prevalence, risk factors, and molecular detection of Campylobacter isolates from 540 farmed cattle of 90 herds. As an individual sample, 540 feces, and as a pooled sample, 180 milk samples, 90 feed samples, 90 water samples, 90 manure samples, and 90 animal attendants' hand-rinse water were collected and tested via culture, biochemical, and molecular assays. A pretested semi-structured questionnaire was used to collect herd-level data on risk factors with the herd owners. The herd-level data on risk factors were analyzed through univariate and multivariate analyses, and a p-value <0.05 was considered statistically significant for all analyses. Overall, farm-level prevalence of bovine Campylobacter was enumerated to be 53.3% (95% confidence interval [CI]: 42.5–63.9%). The feces sample was found to be a high level of contamination of 30.9% (95% CI: 27–35%) followed by the manure swab (pooled) at 15.6% (95% CI: 8.8–24.7%). Campylobacter jejuni was documented as an abundant species (12.6%), followed by Campylobacter coli (5.1%), and Campylobacter fetus (0.3%). Older farms (>5 years of age), no/minimum cleaning and disinfection practices, along with animal roaming outside of the farm, were documented as significant risk factors for farm-level Campylobacter occurrence. Evidence-based control measures need to be taken through stringent biosecurity and hygienic measurement to lessen the load of the Campylobacter pathogen in the farm environment and prevent further transmission to animals and humans.

Arsenic contamination in groundwater has become a worldwide problem. Currently an unprecedented number of people in West Bengal, India and Bangladesh are exposed to the ubiquitous toxicant via drinking water in exposure levels far exceeding the maximum recommended limit laid down by WHO. This arsenic epidemic has devastated nine districts of West Bengal encompassing an area of 38,865 km2 leading to various clinical manifestations of chronic arsenicosis. We conducted a human bio-monitoring study using chromosomal aberrations (CA) and sister chromatid exchanges (SCE) as end points to explore the cytogenetic effects of chronic arsenic toxicity in the population of North 24 Parganas, one of the arsenic affected districts in West Bengal. Study participants included 59 individuals residing in this district where the mean level (±S.E.) of arsenic in drinking water (μg/l) was 211.70±15.28. As age matched controls with similar socio-economic status we selected 36 healthy, asymptomatic individuals residing in two unaffected districts—Midnapur and Howrah where the mean arsenic content of water (μg/l) was 6.35±0.45. Exposure was assessed by standardized questionnaires and by detecting the levels of arsenic in drinking water, nails, hair and urine samples. In the exposed group the mean arsenic concentrations in nails (μg/g), hair (μg/g) and urine (μg/l) samples were 9.04±0.78, 5.63±0.38 and 140.52±8.82, respectively, which were significantly high (P<0.01) compared to the corresponding control values of 0.44±0.03, 0.30±0.02 and 5.91±0.49, respectively. Elevated mean values (P<0.01) of the percentage of aberrant cells (8.08%) and SCEs per cell (7.26) were also observed in the exposed individuals in comparison to controls (1.96% and 5.95, respectively). The enhanced rates of CAs and SCEs among the residents of North 24 Parganas are indicative of the cytogenetic damage due to long term exposure to arsenic through consumption of contaminated water.

An examination of women's experience on public transport in Bangladesh and Cambodia found that victimization does reduce perceived safety or transport use. In a cultural context where women are socialized to fear and avoid public spaces, experiencing victimization may confirm rather than change previous beliefs. Moreover, it is possible that the participants' use of public transport was driven by necessity rather than choice and that they were unable to change travel patterns in response to victimization. These findings underscore the importance of targeting public violence toward women and the broader societal norms that limit their participation in public life. [ABSTRACT FROM AUTHOR]

This study explores the role of diverse climatic vulnerabilities and socio- economic variables in explaining Bangladeshi rural households' livelihood choices and the synergies that exist across the choices. We develop a multivariate probit model for analysing a dataset of 5,604 households that is representative of rural Bangladesh. The findings reveal a landscape where agriculture-based strategies predominate, with households strategically combining various approaches. Households complement agriculture-based strategies, while substituting beyond agriculture-based strategies. Climate stressors such as flood, salinity, river erosion, drought, storms and cyclones induce notable shifts in livelihood choices. Among these, the most prominent is the substantial influence of storm and cyclone vulnerability. Migration is more prevalent in areas susceptible to salinity, storms and cyclones, while casual labour prevails in drought-prone and flood-vulnerable regions. Households residing in the economically marginalized and environmentally vulnerable feed-the-future (FtF) zone make distinct decisions regarding income strategies compared to their counterparts in other rural areas across the country. Households in this zone exhibit a higher likelihood of opting for specific agriculture-based income sources and casual labour, while self-employment, migration and salaried jobs are less favoured. Furthermore, we elucidate the pivotal role of infrastructure, information access and institutional factors in shaping income sources. Households in different divisions make distinct livelihood choices, especially in agriculture. Ultimately, the findings advocate for precise interventions tailored to climate vulnerabilities. This includes enhancements in road connectivity, the utilization of mobile banking and the provision of extension services, with a specific focus on geographically marginalized and climate-vulnerable regions.

The study investigates the factors behind growing communal violence in Bangladesh that is mostly perpetrated against non-Muslim communities by examining three different cases. The qualitative study has been undertaken with the help of available secondary resources and in-depth interviews of experts as primary sources. The findings confirm that the ongoing communal violence in Bangladesh is not spontaneous but rather comprises deliberate and well-orchestrated incidents. It has been noted that apart from communal identity or ideological discord, other factors have played a pivotal role in these constant attacks. All these attacks are primarily intertwined with local politics and power relations as there is evidence of local political leaders' and members' involvement in the assaults. Besides, the entrenchment of extremist elements and growing intolerance at the mass level have a formidable impact on the gradual alienation of non-Muslim communities. The inaction of the state agencies and a culture of impunity have been largely responsible for the deterioration of communal harmony in Bangladesh. Due to these factors, no organised cultural campaign or resistant mechanism could gain a strong foothold against communal violence. [ABSTRACT FROM AUTHOR]

The aim of this study is to investigate the influence of transformational leadership on employees' change championing behaviour, and the mediating roles of employees' trust in leadership and employees' work engagement in the relationship between transformational leadership and employees' change championing behaviour. The research was conducted among 379 employees in the banking sector of Bangladesh. The findings revealed a significant and positive impact of transformational leadership on employees' change championing behaviour. Furthermore, the study identified that employees' trust in leadership and work engagement play important mediating roles, individually and sequentially, in the relationship between transformational leadership and employees' change championing behaviour during change management in the Bangladesh banking sector. This study contributes to our understanding of how transformational leadership promotes employees' change championing behaviour and underscores the effectiveness of transformational leadership in fostering employees' trust in leadership and work engagement. Additionally, this study emphasises the importance of employees' trust in leadership and work engagement in the context of organisational change implementation. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to assess the impact of determinants on the effectiveness of internal audit (IA) within the banking industry of Bangladesh. Design/methodology/approach: The data was obtained through 152 survey questionnaires from a total of 43 privately owned and six state-owned commercial banks in Bangladesh. The analysis was conducted using structural equation modeling. Findings: The findings demonstrate that the independence of internal auditors and the quality of IA substantially impact enhancing the efficiency of IA. On the other hand, the competence of internal auditors and management support in IA functions do not significantly impact the effectiveness of IA. Practical implications: The study's findings may have significant policy implications for the government, regulators, internal auditors, management committees and other stakeholders in establishing programmes to enhance the efficacy of IA as a component of banking audit management reforms. Originality/value: This study makes three distinct contributions to the existing literature. Firstly, previous literature focused on the determinants affecting the external audit efficiency of the public companies and banking sectors in Bangladesh (Hasan, 2018; M. M. U. Reza, 2021). In this study, the author enhances the research by presenting empirical findings on the IA effectiveness of banks. Secondly, the author expands the research by incorporating both private and state-owned commercial banks as samples. Thirdly, the study is unique given that it investigates the effectiveness of IA in response to the recent financial scandals in the banking industry of Bangladesh (The Daily Star, 2023).

Balanced energy protein (BEP) supplementation is an efficacious intervention in pregnancy for improving birthweight and is recommended by World Health Organization (WHO) in countries with high maternal undernutrition. Few countries have implemented BEP programmes due in part to high cost, lack of data on acceptability and feasibility, and complexity of delivery. We sought to address implementation gaps in BEP interventions through a formative study designed to understand implementation outcomes. We conducted 52 in‐depth interviews and 8 focus‐group discussions with married women of reproductive age, family members, health care providers and pharmacists in three unions of the Gaibandha district in rural Bangladesh. Interviews were translated and transcribed in English and analysed using an analytic framework for implementation science in nutrition. BEP was viewed as an acceptable and appropriate intervention to combat undernutrition in this setting. There was a lack of clarity on who should or could be responsible for providing/distributing BEP in a way convenient to mothers. Many participants preferred door‐to‐door delivery and thought this approach could address social and gender inequities, but providers mentioned already being overworked and worried about adding new tasks. Participants were concerned about the affordability of BEP and opportunity costs associated with travel to proposed distribution sites such as ANC or pharmacies. Women in these communities do not always have the agency to travel without supervision or make purchasing decisions. BEP supplementation is a complex intervention; future trials seek to assess ways to overcome these implementation challenges and inform a long‐term systems‐owned BEP intervention. Key messages: Balanced energy protein (BEP) supplementation is an efficacious intervention in pregnancy for improving birthweight but its implementation through ANC, as recommended by WHO, is complex.Decisions about who bears the cost of the product should consider the feasibility of scaling solutions to different groups. Targeting the most in need and with government supported programmes should be considered.Door‐to‐door distribution emerged as the preferred delivery modality, though the feasibility of this mechanism at scale is a concern, particularly given the documented lack of human resources in health.Given the positive community perceptions around BEP supplements, delivery through ANC could increase ANC participation.

Dengue is an important vector-borne disease occurring globally. Dengue virus (DENV) infection can result in a potentially life-threatening disease. To date, no DENV-specific antiviral treatment is available. Moreover, an equally effective panserotype dengue virus vaccine is not available. Recently, two DENV vaccines, Dengvaxia and Qdenga, were licensed for limited use. However, none of them have been approved in Bangladesh. DENV is transmitted by Aedes mosquitoes, and global warming caused by climate change favoring Aedes breeding plays an important role in increasing DENV infections in Bangladesh. Dengue is a serious public health concern in Bangladesh. In the year 2023, Bangladesh witnessed its largest dengue outbreak, with the highest number of dengue cases (n  =  321,179) and dengue-related deaths (n  =  1,705) in a single epidemic year. There is an increased risk of severe dengue in individuals with preexisting DENV-specific immunoglobulin G if the individuals become infected with different DENV serotypes. To date, vector control has remained the mainstay for controlling dengue; therefore, an immediate, strengthened, and effective vector control program is critical and should be regularly performed for controlling dengue outbreaks in Bangladesh. In addition, the use of DENV vaccine in curbing dengue epidemics in Bangladesh requires more consideration and judgment by the respective authority of Bangladesh. This review provides perspectives on the control and prevention of dengue outbreaks. We also discuss the challenges of DENV vaccine use to reduce dengue epidemics infection in Bangladesh.

Background: Covid 19 was declared as a public health emergency by the World Health Organisation (WHO) due to its rapid spread and catastrophic effects on health. It affected around 119 M people with mortality rate of 0.27% worldwide, including South-Asians. This review aims to understand the risk perceptions, cultural religious beliefs and the coping mechanisms of South Asians during the Covid 19 pandemic. Methods: We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The following search engines were used: Medline, Cochrane Library, PsycINFO, CINAHL, and Web of Science. Included studies investigated perceptions and opinions of individuals on knowledge, risk and protective factors, native faith based practices, and attitudes towards the COVID-19 pandemic. Results: The database search produced 282 articles to screen. The final narrative synthesis included five studies comprising of 13,476 participants from Pakistan, India, Nepal, and Bangladesh. Ten studies, comprising 7,893 participants, were eligible and included for meta-analysis. The overall pooled prevalence with maximum heterogeneity for correct knowledge of symptoms, hand washing or use of sanitizers, face masking use of herbal or traditional remedies and physical distancing or avoidance of contact was reported through meta-analysis. Conclusion: The review brings forth a useful comparison of individual and cultural differences in KAP, risk perceptions and coping strategies. This review highlights the need for and importance of tailored information dissemination, culturally sensitive risk communication, targeted educational interventions, community engagement and empowerment, policy, and infrastructure improvements, as well as continued research and data collection. By addressing these implications, efforts to mitigate the impact of COVID-19 can be more effective and equitable across diverse populations. Prospero registration: CRD42021246475.

This article examines the social and economic adaptation mechanisms practiced by the hijra community in Bangladesh, with a particular focus on the family structure and social relations. It posits that an analysis of hijra family dynamics may be effectively conducted by including theories of social adaptation and economic exploitation, drawing upon qualitative data. As the hijra children undergo maturation and manifest their sexual and behavioural distinctiveness, the familial outlook on the children experiences a transformation as time progresses. Hijra children are ultimately subjected to parental and societal neglect, rejection and discrimination, which in turn push them to establish an independent existence under hijra community. Within the community, the establishment and nurturing of the familial bond between the guruma, who serves as the head of the family, and the chela, who assumes the role of the disciple, is facilitated through a shared sense of affinity and unwavering loyalty. Furthermore, a significant correlation exists between hijra families and their economic system. The chela hijras, who have experienced separation from their biological families, seek shelter under the care of a guruma. Consequently, they endure processes of social and economic adaptation. However, they also experience economic exploitation from the guruma. This study applies a combination of primary and secondary sources of data, and Case Studies, In-depth Interviews and Key Informant Interviews (KIIs) have been used to collect firsthand data. The research findings shed light on the process through which hijras are integrated into the community, as well as the various forms and degrees of economic exploitation they encounter. Thus, this article contributes to the existing body of literature on the issues of third gender and the vulnerabilities they face and what measures should be taken for their inclusive development.

The 'Ultra-poor Graduation' model, though highly effective in poverty alleviation, costs substantially more than alternative poverty alleviation approaches. One possible way of improving the cost-effectiveness of the model is to analyse the treatment effect heterogeneity and identify the participants who do not gain much from the programme and better customise the interventions to their needs. Applying recently developed machine learning methods on a large-scale RCT dataset from Bangladesh, we identify and characterise the program participants who benefit and who do not. We find significant variation in impact on assets where the top quintile gainers experience asset growth of 337% while asset growth is only 189% for the bottom quintile. Heterogeneity in impact on household expenditures is found to be present but of lower magnitude than that of assets. Importantly, the machine learning techniques we apply reveal contrasts in characteristics of beneficiaries who made the most in assets vs. consumption. The most benefitted households in per-capita wealth outcome were relatively older, were more dependent on wage income, had less involvement in self-employment activities, and had lower participation in household decision-making at baseline. In contrast, the top quintile gainers of household expenditure are younger, earn less from wages, depend more on self-employment income, and have higher participation in household decision-making. The results identify beneficiary characteristics that can be used in targeting households either to maximise impact on the desired dimension and/or to customise interventions for balancing the asset and consumption trade-off.

Background: Despite being preventable, cervical cancer remains a leading cause of mortality among Bangladeshi women. This article addresses the trends in Bangladesh's response to the World Health Organization's (WHO) request for the eradication of cervical cancer within the nation. Discussion: When it comes to cervical cancer, healthcare institutions need to be concerned in terms of protocols for diagnosis and treatment, staff education, and available resources. More than a quarter of all female cancers in Bangladesh are caused by cervical cancer, which can be prevented through better healthcare infrastructure, earlier diagnosis, more qualified healthcare professionals, improved urban and rural hospital infrastructure, community‐based clinics, expanded affordable vaccinations, school‐based delivery systems, adoption of single‐dose vaccine schedules, raising awareness, and compiling a registry of previously affected results. WHO applauds Bangladesh's Ministry of Health and Family Welfare for its efforts to develop the National Strategy for cervical cancer prevention and control, which will guide and strengthen the country's activities to prevent and treat cervical cancer. Conclusion: The endeavor to eradicate this global disease burden should not be limited to Bangladesh; all nations should participate collectively to prevent the malignancy from returning and threatening human civilization.

Background: Epidemics of the dengue virus can trigger widespread morbidity and mortality along with no specific treatment. Examining the spatial autocorrelation and variability of dengue prevalence throughout Bangladesh's 64 districts was the focus of this study. Methods: The spatial autocorrelation is evaluated with the help of Moran I $I$ and Geary C $C$. Local Moran I $I$ was used to detect hotspots and cold spots, whereas local Getis Ord G was used to identify only spatial hotspots. The spatial heterogeneity has been detected using various conventional and spatial models, including the Poisson‐Gamma model, the Poisson‐Lognormal Model, the Conditional Autoregressive (CAR) model, the Convolution model, and the BYM2 model, respectively. These models are implemented using Gibbs sampling and other Bayesian hierarchical approaches to analyze the posterior distribution effectively, enabling inference within a Bayesian context. Results: The study's findings show that Moran I $I$and Geary C $C$analysis provides a substantial clustering pattern of positive spatial autocorrelation of dengue fever (DF) rates between surrounding districts at a 90% confidence interval. The Local Indicators of Spatial Autocorrelation cluster mapped spatial clusters and outliers based on prevalence rates, while the local Getis‐Ord G displayed a thorough breakdown of high or low rates, omitting outliers. Although Chattogram had the most dengue cases (15,752), Khulna district had a higher prevalence rate (133.636) than Chattogram (104.796). The BYM2 model, determined to be well‐fitted based on the lowest Deviance Information Criterion value (527.340), explains a significant association between spatial heterogeneity and prevalence rates. Conclusion: This research pinpoints the district with the highest prevalence rate for dengue and the neighboring districts that also have high risk, allowing government agencies and communities to take the necessary precautions to mollify the risk effect of DF.

This study investigates the relationship between Foreign Direct Investment (FDI) inflows and economic growth at sectoral levels in Bangladesh, employing a panel study framework. Utilizing sectoral-level panel data spanning six sectors from 2007–08 to 2018–19, the analysis is conducted using Panel Vector Error Correction Model (Panel VECM). Results from panel unit root tests confirm that all variables are integrated of order one I (1), indicating stationarity. The Pedroni panel co-integration test further supports the presence of co-integration among the variables. Notably, the Panel VECM reveals evidence of a unidirectional causal relationship from Real Gross Domestic Product (RGDP) to Real Foreign Direct Investment (RFDI) across all six sectors of Bangladesh. The findings underscore the significance of formulating pragmatic policies and implementing them effectively to attract FDI across sectors, thereby contributing to the overall economic growth of Bangladesh.

This study aimed to develop a geochemical database by thoroughly analyzing groundwater and sediments from coastal aquifers of southwest Bangladesh. Moreover, we investigated the source of sediment deposition and the mechanisms behind the presence of arsenic and salinity in groundwater. The seasonal distribution patterns of arsenic among the shallow and deep coastal aquifers were found to be 45.12 µg/l and 20.65 µg/l during dry and wet seasons, respectively. Moreover, the groundwater salinity distribution ranged from 3262.88 mg/l to 1930.88 mg/l during the dry and wet seasons. Cored sediment samples showed fine to medium sands of 92%, with silt and clay particles. The petrographic study of authigenic and heavy minerals revealed that the mineral grains were subangular to angular, indicating their textural immaturity of coastal sediments. The reactivity of goethite (FeOOH) and siderite (FeCO3) minerals suggests that the aquifers were subjected to slightly oxidized to moderately reducing conditions, with ORP values ranging from +50.40 mv to −149.5 mv. Such redox conditions could potentially result in the enrichment and mobility of arsenic in the groundwater. Although arsenic concentrations in deep aquifers are relatively low, higher salinity values are found in both shallow and intermediate coastal aquifers. [ABSTRACT FROM AUTHOR]

Introduction: Lumpy skin disease (LSD) is a highly contagious vector-borne viral disease of cattle. LSD has emerged in Bangladesh in 2019, causing significant economic losses due to its high morbidity and mortality. This research was designed to isolate, identify, and assess the immunogenicity of LSD virus (LSDV) using nodular tissue samples obtained from affected cattle during the 2019-20 outbreak across nine districts of Bangladesh. Methods: To determine the presence of LSDV in nodular tissues, we initially used iiPCR and PCR, followed by histopathological examination. 151 were positive via iiPCR and PCR among the 180 collected samples. The PCR positive 151 samples were then inoculated into 10-day-old embryonated chicken eggs via the CAM route to isolate LSDV, confirmed through PCR. Subsequently, partial sequencing and phylogenetic analysis of the P32 gene were performed to determine the origin of the circulating LSDV strain. The immunogenicity of selected LSDV strains was assessed through an ELISA test. Results: The PCR results revealed a distinct positive band at 192 bp in both the nodular tissue samples and the LSDV isolated from chicken embryo inoculations. Microscopic analysis of the nodular lesions revealed thickening of the epidermis, ballooning degeneration of keratinocytes, and proliferation of follicular epithelia. Additionally, mononuclear infiltration was observed at the demarcation line between infected and healthy tissue, with necrosis of muscular tissues beneath the epidermis. The LSDV isolate from Bangladesh exhibited a close genetic relationship with LSDV strains isolated from neighboring and other regional countries including India, Myanmar, and Mongolia. This observation strongly suggests the possibility of a transboundary spread of the LSD outbreak in Bangladesh during 2019-2020. The results of the immunogenicity test showed that the serum antibody titer remained at a protective level for up to 18 months following secondary immunization with inactivated LSDV antigen. This finding suggests that the inactivated LSDV antigen could be a potential vaccine candidate to protect cattle in Bangladesh against LSDV. Conclusion: In conclusion, our research successfully isolated, identified, and characterized LSDV in cattle nodular tissues from the 2019-20 outbreak in Bangladesh. Furthermore, it provided insights into the probable origin of the circulating strain and investigated a potential vaccine candidate to protect cattle in the region from LSDV. [ABSTRACT FROM AUTHOR]
