Article Synopsis
- * A study conducted in South Africa found an overall seroprevalence of 2.3% among dairy cattle, with significant variations across provinces; KwaZulu-Natal had the highest rate at 7.5%.
- * Factors influencing seropositivity included higher odds in Holstein-Friesian breeds, increased risk linked to cows left on pasture, and the purchase of replacement animals, while good hygiene practices served as a protective factor.

Article Synopsis
- The study focused on detecting and analyzing Shiga toxin-producing E. coli (STEC) and Enteropathogenic E. coli (EPEC) in 771 fecal samples from dairy cattle in South Africa.
- Results showed that 42.2% of the samples were positive for STEC and 23.3% for EPEC, with a total of 53 different STEC serotypes and 19 EPEC serotypes identified.
- The findings highlight dairy cattle as a significant reservoir for these pathogens, indicating a need for further research to understand their potential impact on foodborne diseases in humans.
Bovine theileriosis (caused by Theileria parva) is the most important tick-borne transboundary animal disease endemic to Zimbabwe, yet its distribution dynamics data in the country remain scant and outdated. A retrospective study was conducted to determine high-risk areas of bovine theileriosis and associated risk factors in Zimbabwe. Records on bovine theileriosis spanning 23 years (January 1995 to December 2018) were obtained from the Epidemiological Unit of the Division of Field Veterinary Services of Zimbabwe (DVSZ).

Apart from causing reproductive failure in animals it is also a significant zoonotic concern. The objective of this study was to determine the seroprevalence and associated risk factors of T.

Individual fecal samples were collected on three occasions over a 4-month period from each of 30 lions (55%) out of 55 animals held. The samples were examined using flotation and sedimentation techniques to assess the presence and count of parasite eggs, oocysts, and cysts per gram of feces as well as larvae identification.
