Therefore, the aim of this study was to assess the drug- and multidrug-resistance pattern of Enterobacteriaceae isolated from chicken droppings at Jimma University poultry farm, College of Agriculture and Veterinary Medicine, southwest of Ethiopia.Methods: A cross-sectional descriptive study was conducted from April, 2018 to June, 2018. A total of 140 fresh chicken dropping samples were collected and transported to Jimma University Medical Microbiology Laboratory for analysis. All samples were inoculated on MacConkey agar and xylose lysine deoxycholate agar. Gram stain and relevant biochemical tests were done for identification of isolates. Antimicrobial susceptibilities were tested by the Kirby–Bauer disk diffusion method.Results: Out of 140 chicken dropping samples, 61 (43.6%) showed bacterial growth. Of these, E. coli accounts for 39.0% followed by K. pneumoniae (22.0%), P. mirabilis (19.3%), and Salmonella species (17.7%). With regard to antibiotic resistance pattern, E. coli demonstrated a high rate of resistance against ampicillin (91.7%), tetracycline (75.0%), and trimethoprim-sulfamethoxazole (70.8%). K. pneumoniae showed a high resistance rate against ampicillin, trimethoprim-sulfamethoxazole, and tetracycline, with a resistance rate ranging from 76.9% to 85.6%. P. mirabilis and Salmonella spp. also showed high resistance against ampicillin, tetracycline, and trimethoprim-sulfamethoxazole with a resistance rate ranging from 72.7% to 83.3%. All isolates relatively showed lower resistance rates with a range of 20.8% to 41.7% against third-generation cephalosporins (ceftazidime and ceftriaxone), ciprofloxacin, and gentamicin. Totally, 32 (52.5%) of the isolates showed MDR against three or more antibiotics.Conclusion: Antibiotic resistant isolates against commonly prescribed single and multiple drugs were common. This highlights that chickens in the farm may serve as the reservoirs of antibacterial resistant bacteria that might infect humans through the food chain. Therefore, emphasis on the usage of antibiotics in chicken farms has to be considered.Keywords: drug- and multidrug-resistance, Enterobacteriaceae, chicken droppings, Ethiopia

Background Raw meat is one of the commonly consumed traditional diets in Ethiopia. However, unhygienic processing and distribution practices are risky for contamination of meat leading to human infection. This study was conducted to assess the presence of multi-drug resistant E. coli with special emphasis on E. coli O157:H7 from meat of cattle and swab samples at abattoir houses and butcher shops in Jimma town, Southwest district of Ethiopia. Methodology A cross-sectional descriptive study was conducted from April to July, 2018. The isolation and identification processes passed through enrichment of samples with modified tryptone soy broth (mTSB), streaked onto MacConkey agar and Cefixime-tellurite sorbitol MacConkey agar, biochemical testing (indole and TSI), followed by latex agglutination testing. Results Out of 505 samples, 102 (20.2%) and 27 (5.4%) were positive for E. coli and E. coli O157:H7, respectively. Of these, 55 (19.3%) and 47 (21.4%) of E. coli and 17 (6.0%) and 10 (4.5%) of E. coli O157:H7 were isolated from the abattoir and butcher shop samples, respectively. A significant difference in the occurrences was observed among sample sources. Antimicrobial susceptibility test results showed that, 92.2% to 96.1% of E. coli and 85.5% to 96.3% of E. coli O157:H7 were susceptible to third generation cephalosporin, ciprofloxacin, gentamycin, kanamycin, streptomycin, and chloramphenicol. About 91.2% and 97.1% of E. coli and 88.9% and 92.6% of E. coli 0157:H7 were resistant to ampicillin and erythromycin, respectively. A total of 57 (44.2%) E. coli and E. coli O157:H7 isolates were resistant to three or more classes of antibiotics. All abattoir and butcher shop workers did not have any formal education or training certificates on food safety, and unhygienic practices were also observed. Conclusion The presence of E. coli and E. coli O157:H7 including multi-drug resistant isolates in raw meat highlights how the current meat processing and distribution practice was unhygienic. Therefore, strategies in the prevention and control of food-borne infections that could be caused by multi-drug resistant strains will depend greatly on hygienic processing and distribution practices of meat.

Background Schistosoma mansoni (S. mansoni) infection is a significant public health problem in Ethiopia, and has wide distribution in the country. The impact of the disease is particularly high on school-age children. Nationwide 385 endemic districts were identified, whereby control and elimination interventions are underway using school-based annual mass drug administration (MDA) with praziquantel. The national elimination program targets endemic districts as a whole. The aim of this study was to identify the transmission foci of Schistosoma mansoni and determine prevalence of soil-transmitted helminths (STHs) in Abeshge district. Methods The study was conducted from April to May, 2019 among school-age children randomly selected from public elementary schools in Abeshge district, South-central Ethiopia. Demographic information and data on risk factors of S. mansoni infection were gathered using pre-tested questionnaire. Moreover, a stool sample was collected from each child and examined using Kato-Katz thick smear technique. The data were analyzed using STATA_MP version 12. Results A total of 389 school-age children from five public elementary schools were included in the study. The overall prevalence of S. mansoni and STHs was 19.3% (75/389) and 35% (136/389), respectively. The prevalence of S. mansoni was 60.6% in Kulit Elementary school, while it was zero in Geraba. The prevalence of S. mansoni was significantly higher among males (AOR = 2.6, 95% CI 1.3–5.1), those with habit of swimming and/or bathing in rivers (AOR = 2.9, 95%CI 1.3–5.1) and involved in irrigation activities (AOR = 2.9, 95% CI 1.0–8.3). Overall, the prevalence of S. mansoni was significantly higher among school children attending Kulit Elementary School compared to those attending the remaining schools (AOR = 12.5, 95%CI 6.2–25.1). Conclusion A wide variation of S. mansoni prevalence was observed among the school children in the different schools. Control interventions better identify and target foci of S. mansoni transmission, instead of targeting the district homogenously.

Background. Helminths are significant contributors to global health problems. Subgroup soil-transmitted helminths are among the listed neglected tropical diseases. The rural inhabitants often suffer from heavy infection, particularly children and pregnant women. Objective. The study aimed at determining the magnitude and intensity of soil-transmitted helminth infection and associated risk factors in the study area where the prevalence and intensity of the infection are yet unknown at the community level. Method. A community-based cross-sectional study was conducted between April and June 2016 on 377 individuals. Systematic random sampling was utilized to select the households. Lottery method was used for study subject selection in the households. Sociodemographic and risk factor data were collected using a pretested questionnaire. Parasitological tests were processed using Kato-Katz thick smear and duplicate direct wet mount analysis of the stool sample. Results. A total of 377 subjects aged from 2 to 55 years were enrolled in the study, of which 211 were female (56%) and 166 were male (44%). The overall prevalence of soil-transmitted helminths was 265 (70.3%). The females shared more (36.6%, 138) as compared to males (33.7%, 127) at P<0.05. Of all identified soil-transmitted helminths, Trichuris trichiura was the predominant infectious agent (66.8%, 252) followed by Ascaris lumbricoides (16.4%, 62) and hookworm (14.1%, 53). Gender (AOR: 1.67 (95% CI: 1.034–2.706)), lack of fruit washing before consumption (AOR: 1.7 (95% CI: 1.1–2.6)), open defecation habit (AOR: 1.75 (95% CI: 0.921–3.338)), and drinking untreated water (AOR: 1.994 (95% CI: 1.019–3.90)) were significantly associated with soil-transmitted helminth infection. Conclusion. High prevalence of STH infection was still an important health issue of the community even after the implementation of the health extension program. Hence, intervention considering all population of the residents as eligible to deworm and health education are mandatory.
