A cross-sectional study was conducted from May 2023 to March 2024 to estimate the prevalence and associated risk factors of toxoplasmosis among sheepand pregnant women in Injibara town. Serum was collected from ovine and pregnant women.Interview was conducted with eligible mothers to obtain socio-demographic and behavioral datausing structured questionnaires. All factors attributing to T. gondii infection in sheep andpregnant women were analyzed using logistic regression analysis. The seroprevalence of T. gondii infection in ovine was 47.40%. A significant association was observed betweenseroprevalence and sex, age and flock size. Young ovines (OR: 2.34, (2.00-4.34), P=.000 were2.34 times more likely being infected with T. gondii compared to adult ovine. On the other hand, female ovines (OR: 1.26, (3.45-8.01, P=.000) were 1.26 times more likely being infected than male sheep. Whereas above 20 flock size (OR: 3.65, (0.34-7.66, P = 0.041) were 3.65 times morelikely being infected than other flock size. In pregnant women, the T. gondii seroprevalenceswere 59.65%. This study showed high seropositivity for T. gondii among sheep and pregnantwomen in Injibara town. Therefore, further studies on isolation and genotype of the pathogen arecrucial. It also requires action to prevent and control the infection in pregnant women, which poses a potential threat to the foetus. 2024-06-01T00:00:00Z http://ir.bdu.edu.et/handle/123456789/12979 SEROPREVALENCE AND ASSOCIATED RISK FACTORS OF TOXOPLASMA GONDII INFECTION AMONG OVINE AND PREGNANT WOMEN IN DEBRE BIRHAN CITY, ETHIOPIA Adugnaw Asmare Toxoplasmosis is a worldwide zoonotic disease caused by Toxoplasma gondii with harmful effects on animal and human health. Cross-sectional study was designed and conducted from January 2021 to March 2021 to estimate the prevalence and associated risk factors of toxoplasmosis among sheep and pregnant women in Debre Birhan city. Serum was collected from jugular vein of each sheep. Serum was also collected from pregnant women and exit interview was conducted with eligible mothers to obtain socio-demographic and behavioral data using structured questionnaires. All factors attributing to T. gondii infection in sheep and pregnant women were analyzed using logistic regression analysis. The seroprevalence of T. gondii infection in sheep was 46.3%. A significant association was observed between seroprevalence and sex, age and water source and significantly higher in female sheep (OR: 1.78, 95% CI: 1.16-2.74, P = 0.008), adult age (OR: 2.26, 95% CI: 1.46-3.49, P = 0.00) and river water (OR: 2.14, 95% CI: 1.22-3.74, P = 0.008). In pregnant women, the T. gondii seroprevalences were 61.2%. Multivariable logistic regression analysis showed that the risk of T. gondii infection was significantly higher in age of (35-36) (OR: 3.00, 95% CI: 1.57-5.75, P = 0.001), eating raw meat OR: 1.64, 95% CI: 1.03-2.59, P=0.036) spring water source (OR: 1.94, 95% CI:(3.29, P = 0.014) and contact with cats (OR: 1.68, 95% CI: 1.06-2.64, P = 0.027). This survey showed high seropositivity for T. gondii among sheep and pregnant women in Debre Berhan city. Therefore, further studies on isolation and genotype of the pathogen are crucial. It also requires action to prevent and control the infection in pregnant women, which poses a potential threat to a foetus.

A cross-sectional study was carried out from November 2020 to April 2021 in Jawi district of Northwest Ethiopia to estimate the prevalence of bovine trypanosomiasis, determine the apparent density (AP) of tsetse flies, identify the potential risk factors, and assess economic impact of the disease. For the parasitological study, immediately after recording potential risk factors, blood samples were collected from 384 randomly selected zebu breed cattle and examined using the buffy coat technique and Giemsa-stained thin smears. For the entomological survey, a total of 60 monoconical traps were deployed in two randomly selected kebeles. For economic impact assessment, economic data were collected using comprehensive and pre-tested structured questionnaire administered to 100 randomly selected households through interview. The overall prevalence of trypanosomiasis was 9.11% (95% CI= 6.43–12.45). The trypanosome species identified were Trypanosoma congolense (57.14%, n = 20), T. vivax (37.14%, n = 13) and mixed infection of T. congolense and T. vivax (5.72%, n = 2). There was statistically significant association (p < 0.05) between age and body condition score (BCS) of cattle and trypanosome infection, but no statistically significant differences were observed for sex, coat color, altitude and kebele (p > 0.05). The mean packed cell volume (PCV) value of infected group (22.46±2.56) was significantly (P < 0.001) lower than non-infected (27.77±2.22) group of animals. A total of 154 flies were captured, 110 tsetse and 44 other biting flies (Stomoxys, n=26 and Tabanus, n=18). The species of tsetse identified was Glossina tachinoides, and the apparent density was 0.61flies/trap/day. The overall economic losses per household and per individual cattle were US$ 1,644.77 and US$ 111.13, respectively. The overall mortality rate was 7.7%, and the largest 0022-01-17T00:00:00Z http://ir.bdu.edu.et/handle/123456789/12938 OCCURRENCE AND ASSOCIATED RISK FACTORS OF SALMONELLA IN SLAUGHTERED CATTLE CARCASS AND SLAUGHTER HOUSE ENVIRONMENT AT MAANDEEQ SLAUGHTERHOUSE, HARGEISA, SOMALILAND. ABDILLAHI IDIRIS A wide range of pathogens play a role in foodborne disease and most of them are zoonotic and have reservoirs in healthy food animals from which they spread to variety of foods Among the pathogens, Salmonella is considered the most prevalent foodborne pathogen worldwide and has long been recognized as an important zoonotic microorganism of economic significance in animals and humans So the aim of this study was to determine the occurrence of Salmonella and risk factors in slaughtered cattle Carcass and slaughterhouse environment in Maandeeq slaughterhouse Hargeisa Somaliland. A cross-sectional study was conducted on slaughtered cattle carcass and slaughter house environment in Maandeeq slaughterhouse Hargeisa Somaliland from June 2020 to September 2021. A total of 402 samples were collected, 134 samples from slaughtered cattle carcass, 256 environmental samples (128 from eviscerating knives and 128 from eviscerating hand). And questioners check list were used to collect data on the hygienic status of the environment and cattle carcass. Standard isolation and identification procedures were performed to identify Salmonella isolates. Out of the total 402 cattle carcass and environmental samples, 25(18.6%) were positive for Salmonella. Of these, 11(8.2%) were positive for Salmonella from cattle carcass swabs, 8(6%) and 6(4.4%) evisceration hand and evisceration knife, samples were positive for Salmonella respectively. Statistically significant association was demonstrated between the carcass contaminations by Salmonella and environment swab samples Salmonella status (P= 0.022).Wearing protective closing during slaughtering, clean and sanitized floor, hand washing with water and soap before slaughtering, , washing of knife before to start slaughter with water, Put knife in a clear place after slaughtering one cattle have statistically significant association with prevalence of Salmonella in slaughtered cattle carcass, evisceration hand and eviscerating knife (P ˂ 0.05), this study found the highest contamination of Salmonella was detected in cattle carcass than the evisceration hand and eviscerating knife and the main source of contamination is slaughterhouse environment. Therefore, there is a need to maintain proper hygienic practices in Maandeeq Slaughterhouse during slaughtering. KEYWORDS.
