Phytochemical screening and antimicrobial activity of Polygala sadebeckiana Gürke extracts on bacterial isolates from Wound samples of patients with "Shimetere".

BACKGROUND: Modern medicine is not the choice of patients with "shimetere" in the Gurage community owing to their perception of 'parenteral medication use severely aggravates the disease'. For this reason, the root part of Polygala sadebeckiana Gürke is commonly utilized as traditional medicine in the management of the disease. The aim of this study was to evaluate the antimicrobial activity of Polygala sadebeckiana Gürke extract on bacterial isolates from wound samples of patients with "Shimetere". METHODS: The agar well diffusion method was used to evaluate antibacterial activity, and the agar dilution method was utilized to determine minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MICs). The crude extract was tested against isolated bacteria at concentrations of 25, 50, 75 and 100 mg/mL in triplicate (3x). The positive controls were azithromycin (15 µg) and cloxacillin disk (5 µg), and the negative control was dimethylsulfoxide (5%). The group mean comparisons were made using one-way ANOVA at a significance level of p < 0.05, and the results are presented as the mean ± standard deviation. The presence of secondary metabolites from crude extract was checked by standard testing procedures. RESULTS: S. aureus and S. pyrogen were the two identified bacteria from 9 (60%) and 3 (20%) wound samples, respectively. All identified bacterial strains were susceptible to the reference antibiotics. Tannins and saponins were the most abundant secondary metabolites found in the crude extracts. The average inhibition zones of the plant extracts with 100, 75, 50 and 25 mg/mL concentrations were 27, 20.33, 15.25, and 11.96 mm (p < 0.000) for S. aureus and 30.02, 24.50, 19.07, and 15.77 mm (p < 0.000) for S. pyrogen bacteria, respectively. The MIC and MBC of the crude extract were 1.67 and 10 mg/mL for S. aureus and 0.98 and 4 mg/mL for S. pyrogen. CONCLUSION: Polygala sadebeckiana Gürke contained significant tannins and saponins as secondary metabolites and had antibacterial activities against isolated bacteria (S. aureus and S. pyrogen) from "Shimetere". The potential mechanism of antibacterial action of the plant extract was cell wall synthesis inhibition.

Growth monitoring service utilization and its associated factors among mothers of children less than 2 years in Muhir Aklil district, Gurage zone, Southern Ethiopia, 2020.

Introduction: United Nations International Children's Emergency Fund recommends a 100% growth monitoring and promotion coverage, but the prevalence of growth monitoring and promotion service utilization rate in Ethiopia is only 16.9%. Even though Ethiopia is attempting different strategies to cope up with this low rate, the problem is still unresolved. Objective: The aim of this study is to assess the prevalence of growth monitoring service utilization and its associated factors among mothers of children less than 2 years in Muhir Aklil district. Methods: A community-based cross-sectional study was conducted on 443 study participants from 10 February to 8 March 2020. The study participants in the study were selected using simple random sampling technique. The collected data were entered in to EpiData3.1 and exported to SPSS version 23. Bivariate and multi-variable logistic regression analysis was used to identify factors associated with growth monitoring service utilization. Statistically significance was declared at p value < 0.05% and 95% confidence interval. Results: In this study, the overall growth monitoring and service utilization was 32.9%. Fully empowered mothers adjusted odds ratio: 2.7, 95% confidence interval: 1.5-4.3), receiving counseling (adjusted odds ratio: 2.8; 95% confidence interval: 2.0-4.7) and regularly participating on community conversation (adjusted odds ratio: 2.8, 95% confidence interval: 1.8-7.6) were significantly associated with growth monitoring service utilization. Conclusion: Growth monitoring services utilization was 32.9%. Maternal empowerment on decision-making, engaging women on financial control, knowledge of mothers receiving counseling and regularly participating on community conversation were the independent factors for growth monitoring service utilization. The health extension workers should strengthen maternal empowerment and community conversation through increasing maternal awareness.

Impact of annual preventive mass chemotherapy for soil-transmitted helminths among primary school children in an endemic area of Gurage zone: a prospective cross-sectional study.

BACKGROUND AND AIM: School-based preventive mass chemotherapy has been a key component of Ethiopia's national plan for the control of soil-transmitted helminths. Without an impact evaluation on the impact of a deworming program on infection levels, it is unclear whether the deworming program warrants levels of environmental transmission of infection. This study aimed to determine the impact of annual preventive mass chemotherapy for soil-transmitted helminths among schoolchildren in an endemic area of Gurage zone, south-central Ethiopia. METHODS: A repeated school-based quantitative prospective cross-sectional method was employed. Data were collected from study participants selected using systematic sampling with probability proportional to size at baseline and after annual treatment. Fresh stool samples were collected and processed using the Kato─Katz technique at the Wolkite University parasitology laboratory. SPSS-21 was used for data management and analysis. Changes in parasitological variables after treatment were estimated. RESULTS: Overall, 41.1% prevalence and 22.3% mean geometric infection-intensity reduction were found. Reductions in prevalence of Schistosoma mansoni and hookworms were 13.2% and 15.3%, respectively. Similarly, decreases in prevalence were seen in Ascaris lumbricoides and Trichuris trichiura, representing 94.4% and 80.0% reduction rates, respectively, while 25.9% of the children had heavy S. mansoni (≥400 eggs per gram) infections at baseline, which were reduced to 4.5% after annual treatment. Geometric mean infection intensity-reduction rates for hookworms, A. lumbricoides, and T. trichiura were 80.8%, 20.2%, and 96.7%, respectively. CONCLUSION: Annual mass chemotherapy failed to clear soil-transmitted helminths completely in the present study. However, it resulted in a substantial reduction in overall prevalence and infection intensity. Therefore, other than deworming for school children, interventions such as access to improved personal hygiene and environmental hygiene in school should be emphasized to interrupt transmission.
