The aim of this study was to evaluate the antibacterial activities of common spices on the growth of lactic acid bacteria (LAB) isolated from Ethiopian traditionally fermented camel milk and the consumer acceptability of adding isolated LAB to fermented camel milk. The experiment was conducted at Haramaya University between April and December 2021 with fifteen isolated LABs obtained from the Holeta Agricultural Biotechnology Research Center and eight spices commonly used in Ethiopia. The antibacterial activity of each extracted spice was assessed using the disc diffusion method. Spice extracts were evaluated on different test-isolated LABs at 12.5%, 25%, 50%, 75%, and 100% to check if they had antibacterial activity. The sensory evaluation of the fermented camel milk samples was done by seventeen experienced panelists. The results revealed that different extracted spices at varied concentrations influenced the growth of isolated LABs. Ground elder and fenugreek at 100%, 75%, and 50% concentration for P. acidilactici 226NB had the greatest inhibitory effect recorded. Ground elder, black pepper, garlic, turmeric, and rue inhibited the growth of some LABs at a concentration of 25%. Black cumin seeds, fenugreek, and ground elder at 12.5% concentration inhibited the growth of E. faecium 210NB, P. acidilactici 226NB, and P. pentosaceus 301A, respectively. The sensory evaluation showed isolated LABs received ratings of 'moderately liked' and 'slightly liked' colour, aroma, texture, taste and overall acceptability from panelists. All methanol extracted spices were positive, while glycosides were negative for Allium Sativum, according to phytochemical results. [ABSTRACT FROM AUTHOR]

BACKGROUND፡ Pregnancy is a key step for human’s reproduction and continuity of generation. Pregnant women are among at risk groups for the infection of soil-transmitted helminths (STHs). STHs are highly prevalent in low- and middleincome countries due to the deprived environmental sanitation and personal hygiene. Eating soil (geophagia) is also commonly practiced by pregnant women, particularly in developing countries. The aim of this study was to determine the prevalence of STHs and geophagia, and to assess associated factors among pregnant women in Jimma, Southwest Ethiopia. METHODS: A cross sectional study was conducted among 407 pregnant women attending antenatal care (ANC) at different health facilities located in Jimma Town. Data related to sociodemographic and geophagia practice was collected using a structured questionnaire and STH infections status was determined by using McMaster technique. RESULTS: A total of 407 pregnant women were included in this study. The overall prevalence of any STHs was 19.7% (80/407). Ascaris lumbricoides was the most prevalent 45(56.2%), followed by Trichuris trichiura 19(23.8%) and hookworms 12(15%). There were 4(5%) of double infection with A. lumbricoides and T. trichiura. Overall, 71 (17.4%) of the pregnant women responded to practice geophagia. STHs infection was significantly higher among geophagic pregnant women (p<0.01) and pregnant women who practiced geophagia were 3 times more likely (OR 2.9, 95% CI 1.3-4.2) to have the STHs compared to non-geophagic. Out of those who claimed soil eating habits, 59.1% preferred reddish soil type. Geophagia practice was significantly higher during the third trimester as compared to first and second (p<0.05). CONCLUSION: Geophagia is a risky behavior and this study showed a significant association of geophagia practice with STH infections, although the causal relation could not be established.

Giardia duodenalis is a common pathogenic intestinal protozoan parasite with high prevalence in developing countries, especially among children. The distribution of giardia assemblages among humans and their clinical relevance remains controversial. This study aimed to determine the prevalence and assemblage of Giardia among children under 5 years of age in Jimma, Southwest Ethiopia. Employing a case-control design, 606 children presenting with diarrhea at Jimma university medical center and Serbo Health Center were enrolled from December 2016 to July 2018 along with 617 matched controls without diarrhea. Giardia was detected and typed using real-time PCR. Univariate and multivariate regression analysis was performed. The total prevalence of Giardia was 41% (501/1223) and did not differ significantly between cases and controls (40% vs 42%). Prevalence increased by age, with the highest prevalence seen in children aged ≥ 25 months. Children without diarrhea with a history of diarrhea during the last month were more likely to be Giardia positive compared to children with no history diarrhea (OR 1.8 and 95%CI; 1.1-2.9). Regardless of current diarrhea symptoms, assemblage B predominated with 89%, followed by assemblage A (8%) and mixed infection assemblage A and B (3%). We report a high prevalence of Giardia by PCR detection in Jimma, Ethiopia, with assemblage B being predominant. There was a similar distribution of Giardia assemblages between children with and without diarrhea. Increasing age was a risk factor for Giardia infection. Community-based prevention and control strategies need to be employed to decrease the risk of giardia infection., (© 2023. The Author(s).)

Background: The emergence and spread of Plasmodium falciparum resistance to antimalarial drugs necessitated the search for new drugs from natural products. Zingiber officinal Roscoe and Echinops Kebericho Mesfin are traditional herbal medicines widely used for the treatment of malaria in Ethiopia. The aim of the study was to assess the toxicity profile and in vivo antiplasmodial activities of 70% methanol crude extracts of both plant materials against Plasmodium berghei., Methods: Healthy male Swiss Albino mice of age 4-5 weeks and weight 25-36 g were infected by P. berghei. The extracts were administered orally at doses 5000, 2500 and 1250 mg/kg for acute toxicity of E. kebericho Mesfin. Graded doses at 1000, 500 and 250 mg/kg used for four days suppressive studies. Parasitemia, body weight, packed cell volume (PCV) and survival time were determined. SPSS Version 20 was used for the analysis of data of parasitemia, body weight, PCV, and survival times. Statistical significance was determined by one-way ANOVA. Independent t-test was used to compare results. Results were presented as a mean ± standard error of the mean (M ± SEM). All data were analyzed at a 95% confidence interval (α= 0.05)., Results: At the dose of 5000 mg/kg, E. kebericho Mesfin showed no toxic effects. The LD50 of extract could go beyond the dose used. In vivo antiplasmodial activity of extracts showed excellent chemo suppression at 500 and 1000 mg/kg in a dose dependent manner compared with the negative control. The chemo suppressions of the 1000 mg/kg of both plant extracts were 49.53 ± 1.90% and 32.83 ± 1.03%, respectively. The survival times of P. berghei infected mice were also a dose dependent manner while failed to prevent weight loss., Conclusion: The extracts of both medicinal plants showed antiplasmodial activities against P. berghei. It confirmed the literature findings and their traditional uses.
