External ocular infections are of serious global concern, which cause significant visual morbidity and even blindness, particularly in low-income and resource-limited countries. Herewith, we are reporting the profile of bacteria and fungi causing external ocular infections and the associated factors in Arba Minch, southern Ethiopia. An institution-based cross-sectional study was conducted among 259 suspected individuals with external ocular infections from 01 January to 10 June 2020 in Arba Minch General Hospital. The demographic data were obtained using a structured questionnaire, while corneal scrapings and conjunctival swabs were collected for culture. Samples were inoculated onto MacConkey, blood, mannitol salt and Sabouraud dextrose agar plates. Bacteria were characterised using conventional microbiological techniques. Fungal isolates were identified by culture and morphology by means of microscopy. Antibiotic susceptibility tests for bacteria were performed via the Kirby-Bauer disk diffusion technique. A logistic regression analysis determined the association between dependent and independent variables; P values ≤ 0.05 were considered statistically significant. The most common clinical manifestations in culture-proven cases were conjunctivitis (38.6%, n = 100) and blepharoconjunctivitis (25.9%, n = 67). The overall prevalence of external ocular bacterial and fungal infections was 73.2 (n = 115) and 26.8% (n = 42), respectively. Isolates of Staphylococcus aureus (24.8%, n = 39) and Pseudomonas aeruginosa (13.4%, n = 21) were the predominant Gram-positive and Gram-negative bacteria, respectively. The prevalence of multidrug-resistant bacteria was 71.3% (n = 82). The World Health Organisation-prioritised bacteria such as methicillin-resistant S. aureus (61.5%, n = 24), extended-spectrum beta-lactamase (22.6%, n = 12), and carbapenemase-producing Enterobacteriaceae (15.1%, n = 8) were also detected. The prominent fungi recovered from patients with keratitis and conjunctivitis were Aspergillus spp. and Candida albicans, respectively (9.5%, n = 15 each). Age (26-49 years) and family income were statistically associated with ocular infections (P ≤ 0.05). The results provide insights into the characteristics of major ocular bacterial and fungal pathogens circulating in the ophthalmic patients of Arba Minch. Conjunctivitis is the main ocular manifestation observed, with a predominance of S. aureus. More than two-thirds of the ocular bacteria were MDR, and the highest prevalence corresponds to S. aureus. The aggravation of multi-drug resistance, including the WHO-prioritised ones, warrants periodic evaluations., Competing Interests: Declarations.

Biofilm-producing bacteria associated with wound infections exhibit exceptional drug resistance, leading to an escalation in morbidity, worse clinical outcomes (including delay in the healing process), and an increase in health care cost, burdening the whole system. This study is an attempt to estimate the prevalence and the relationship between the biofilm-forming capacity and multi-drug resistance of wound bacterial isolates. The findings intended to help clinicians, healthcare providers and program planners and to formulate an evidence-based decision-making process, especially in resource-limited healthcare settings. This study was done to assess the prevalence of bacterial infections in wounds and the antibiogram and biofilm-forming capacity of those bacteria in patients with clinical signs and symptoms, attending a General Hospital in southern Ethiopia. A cross-sectional study was performed in Arba Minch General Hospital from June to November 2021. The study participants comprised 201 patients with clinically infected wounds. Demographic and clinical data were gathered via a structured questionnaire. Specimens from wounds were taken from each participant and inoculated onto a series of culture media, namely MacConkey agar, mannitol salt agar, and blood agar, and different species were identified using a number of biochemical tests. Antimicrobial susceptibility tests were performed by means of the Kirby-Bauer disc diffusion technique following the guidelines of the Clinical and Laboratory Standards Institute. A micro-titer plate method was employed to detect the extent of biofilm formation. Bivariable and multivariable logistic regression models were applied to analyse the association between dependent and independent variables, and P values ≤ 0.05 were considered as statistically significant. Data analyses were done with Statistical Package for the Social Sciences version 25. Out of the 201 clinically infected wounds, 165 were found culture-positive with an overall prevalence of 82% (95% CI: 75.9-86.9). In total, 188 bacteria were recovered; 53.1% of them were Gram-positive cocci. The often-isolated bacterial species were Staphylococcus aureus, 38.3% (n = 72), and Pseudomonas aeruginosa, 16.4% (n = 31). The Gram-positive isolates showed considerable resistance against penicillin, 70%, and somewhat strong resistance against tetracycline, 57.7%. Gram-negative isolates showed severe resistance to ampicillin, 80.68%. The overall multi-drug resistance (MDR) among isolates was 48.4%. Extended beta-lactamase (ESBL)-producing Gram-negatives and methicillin-resistant Staphylococcus aureus (MRSA) accounted for 49 and 41.67%, respectively; 62.2% of the isolates were biofilm formers and were correlated statistically with MDR, ESBL producers, and MRSA (P < 0.005). The extent of biofilm formation and the prevalence of MDR bacteria associated with infected wounds hint at a public health threat that needs immediate attention. Thus, a more balanced and comprehensive wound management approach and antimicrobial stewardship program are essential in the study setting., (© 2024. The Author(s).)

Background: Concurrent infections or co-infections caused by intestinal parasites and Helicobacter pylori are quite rampant in paediatrics living in endemic areas of sub-Saharan Africa, including Ethiopia, and if left untreated, can result in severe complications and hence must be addressed to ensure their health and well-being., Objectives: To determine the prevalence of intestinal parasitic and H. pylori co-infections and associated factors among paediatric patients with gastrointestinal symptoms who attended the Arba Minch General Hospital (AMGH), Arba Minch, southern Ethiopia, from September to November 2020., Methods: A cross-sectional study was conducted among a study population of 299 paediatric patients with gastrointestinal symptoms who visited AMGH. Stool samples were collected and analysed to detect H. pylori and intestinal parasites. A rapid lateral flow chromatographic immunoassay was employed to identify the H. pylori copra antigen, whereas the latter was detected using wet mount saline preparation and formol-ether concentration method. Socio-demographic, clinical, behavioural and other factors were obtained by means of a pre-tested structured questionnaire. Descriptive statistics and logistic regression analysis were done by Statistical Package for Social Service (SPSS) version 25; P values < 0.05 were considered statistically significant., Results: The prevalence of Helicobacter pylori and intestinal parasites was 14% (n = 42) and 37.1% (n = 111), respectively, whereas that of the co-infections with these pathogens was 6.4% (n = 19). Giardia lamblia was the most prevailing parasite, 21.4% (n = 64). Informal maternal education [AOR = 5.14; 95% CI: 1.98-15.70] and lack of hand washing practice were significantly associated with the extent of co-infections [AOR = 4.18; 95% CI: 1.36-12.80]., Conclusion: Nearly one in twenty pediatric patients with gastrointestinal symptoms had intestinal parasitic infections and H. pylori co-infections, representing a silent health problem that is to be addressed through effective control strategies. Health administrators should consider the importance of co-infections in clinical diagnosis and planning aimed at its prevention., (© 2024. The Author(s).)

Background: Typical pneumonia is a pressing issue in the treatment of human immunodeficiency virus (HIV) patients, especially in Sub-Saharan Africa, where it remains a significant menace. Addressing this problem is crucial in improving health outcomes and the reduction of the burden of diseases in this vulnerable category of patients., Objective: To determine the prevalence of community-acquired typical pneumonia among HIV patients in Public Hospitals in southern Ethiopia., Methods: A cross-sectional study was done among 386 HIV patients clinically suspected of typical pneumonia attending the anti-retroviral therapy (ART) clinics of two hospitals from March to September 2022. A pretested structured questionnaire was employed to collect the demographic, clinical, and behavioral data. Sputum samples were collected and inspected for bacteria following standard procedures, and antimicrobial susceptibility testing was performed employing the Kirby-Bauer disk diffusion method. Besides, extended-spectrum β-lactamase (ESβL) and carbapenemase-producing Gram-negative bacteria were inspected by the double disk synergy test and modified carbapenem inactivation method. Descriptive and inferential statistical analyses were also done., Results: Overall, 39.1% (151/386) of sputum cultures (95% Confidence Interval: 32.4-44) were bacteriologically positive. A total of 151 bacteria were identified, comprising 72.8% (n = 110) of Gram-negative bacteria. The predominant isolate was Klebsiella pneumoniae (25.8%, n = 39), followed by Staphylococcus aureus (17.9%, n = 27); 59.6% (n = 90) of the entire isolates were multidrug-resistant (MDR). Forty percent (11/27) of S. aureus were methicillin-resistant S. aureus (MRSA), and 28.1% (n = 31) and 20.9% (n = 23) of Gram-negative bacteria were extended-spectrum beta-lactamases (ESBL) and carbapenemase producers, respectively. Occupational status, alcohol consumption, cluster of differentiation4 (CD4) Thymocyte cell count < 350, interruption of trimethoprim-sulfamethoxazole prophylaxis and antiretroviral treatment, and recent viral load ≥ 150 were found statistically significant., Conclusion: The higher rates of MDR, MRSA, ESBL, and carbapenem-resistant Enterobacterales (CRE) indicate that bacterial pneumonia is a vexing problem among HIV patients and therefore it is advisable to implement an antimicrobial stewardship program in the study area., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Assefa et al.

Reproductive tract infections (RTIs) are a persistent public health threat worldwide, particularly among women in low-income countries of Africa, including Ethiopia, where drug resistance is also a growing problem. It is crucial to address this problem to ensure women's health and well-being. A cross-sectional study was carried out among a cohort of 398 women of reproductive age who sought medical attention at the Gynecology Department of the Arba Minch General Hospital, southern Ethiopia, from January to June 2020. They were chosen through systematic random sampling, and a pre-tested structured questionnaire was used to collect the data. The collection of vaginal and/or cervical swabs were done to diagnose bacterial vaginosis (BV) and aerobic vaginitis (AV) using Nugent and AV score analyses, respectively. The swabs were subjected to standard microbiological culture techniques to detect the isolates causing AV and vaginal candidiasis (VC). The susceptibility profiles of the causative agents of AV were checked by the Kirby-Bauer disc diffusion technique. Descriptive and inferential statistical analyses were also done. Aerobic vaginitis was the predominantly diagnosed RTI (n = 122, 30.7%), followed by BV (n = 117, 29.4%) and VC (n = 111, 27.9%). The prominent bacteria of AV were Escherichia coli (n = 36, 34.2%) and Klebsiella pneumoniae (n = 30, 28.5%). The overall rate of multidrug-resistant (MDR) bacteria was 65.71% (n = 69). History of abortion (p = 0.01; AOR = 4.0, 95% CI = 2.1, 7.7) and the habit of using vaginal pH-altering contraceptives (p = 0.01; AOR = 4.7, 95% CI = 2.5, 8.8) have the greatest odds of RTI. The high prevalence of RTIs in our study warrants an urgent intervention to minimize the associated morbidities and complications. The overall rate of MDR bacterial isolates necessitates the implementation of an effective surveillance program in the study setting., (© 2024. The Author(s).)
