Study on gastrointestinal nematode parasite infections of donkey in and around shone town, Hadiya zone, Southern Ethiopia.

One of the most common factors limiting donkey health and productivity is infection with gastrointestinal nematode parasites. From December 2021 to May 2022, a cross-sectional study was conducted in and around Shone town, Hadiya zone, southern Ethiopia, to estimate the prevalence of donkey GIT nematode parasite infection and to assess its associated risk factors. For the coprological examination, 384 simple randomly selected donkeys were sampled from four peasant associations. To identify parasitic eggs in feces, the standard flotation technique was used. In the donkeys examined, the overall prevalence of gastrointestinal nematodes was 75.26% Strongyles (48.17%), Parascaris equorum (11.45%), Strongyloides (5.99%), and mixed infection (Strongyles + Parascaris (9.11%) and Strongyles + Strongyloides (0.52%)) were the most commonly encountered nematodes. There was also a statistically significant difference in the prevalence of donkey gastrointestinal parasites by sex, body condition, and management system (p < 0.05). Donkeys with semi-intensified (OR = 8.99) and poor body condition (OR = 6.48) were at an increased risk of infection compared to intensive management and good body condition. In conclusion, the current study demonstrated that gastrointestinal nematodes are the major health challenges for donkeys in the study area. As a result, strategic regular deworming, improved housing, and feeding management were recommended to improve the health and productivity of donkeys in the study area.

Prevalence and Associated Risk Factors of Cysticercosis bovis in Bishoftu Municipal Abattoir, Central Ethiopia.

Background: Cysticercus bovis has zoonotic implications with economic losses from organ contamination and treatment costs. In developing countries such as Ethiopia, where hygienic standards are low and residents customarily eat raw or undercooked meat, the disease is prevalent. Methods: A cross-sectional study was carried out from December 2021 to June 2022 to determine the prevalence of Cysticercus bovis in cattle slaughtered at the Bishoftu municipal abattoir, in central Ethiopia. Study populations for the active abattoir survey were cattle presented to the abattoir for slaughtering and routine meat inspection conditions. The organ namely the tongue, masseter muscle, liver, and triceps muscle were inspected for the presence of C. bovis. Results: From a total of 330 cattle, 14 were found to be positive for C. bovis, with an overall prevalence of 4.24%. Based on the origin of the animals, the highest prevalence was recorded at Adama (7.27%), followed by Bishoftu (5.45%), Mojo (5.45%), Borana (3.63%), Dukem (3.63%), and Kaliti (0.00%). Similarly, out of 111 adults and 219 old-aged cattle slaughtered and examined at the abattoir, 4.5%, and 4.11% were positive for C. bovis, respectively. Among tested independent variables, sex, body condition score, age, and origin of animals had no relationships with the prevalence of C. bovis. From the detected organ, the tongue ranks first for the highest number of cysts, followed by the masseter muscle, liver, and triceps muscle, with total cysts of 6, 4, 3, and 1, respectively. Conclusion: C. bovis is a prevalent zoonotic parasite disease that causes carcass condemnation; an enhanced understanding of the health consequences of teniasis is required to protect the community.

Study on Salmonella Isolates from Fresh Milk of Dairy Cows in Selected Districts of Wolaita Zone, Southern Ethiopia.

Salmonella infections are most commonly found in animal-derived foods. From December 2021 to May 2022, the researchers conducted a cross-sectional study to determine the prevalence of Salmonella isolated from raw milk collected in and around Areka town, Boloso Sore Woreda, Wolaita Zone, Southern Ethiopia. A total of 151 direct udder milk samples were collected at random and examined using bacteriological methods. The overall prevalence of Salmonella was 9.3% (14/151). Breed, age, body condition, lactation stage, and parity were statistically significant risk factors (p < 0.05). Salmonellosis was more common and statistically significant in dairy cows with poor body condition and late lactation stage, as well as the Holstein Friesian crossbreed, accounting for 17.6%, 19.1%, and 17.3%, respectively. The farm's husbandry hygiene and management system, on the other hand, had no significant association with salmonellosis (p > 0.05). Salmonellosis was generally considered to be moderately prevalent and was one of the diseases of dairy cows in the study area that could have an impact on dairy production and have serious health and financial repercussions. As a result, improvements in milk quality maintenance and assurance are encouraged, and the need for additional research in the study area was suggested along with other ideas.
