Abstract:
Mastitis is a multi-etiological and complex disease, which is inflammation of the
parenchyma of mammary glands mostly by pathogenic microbes, with both local and
systemic manifestations. A cross-sectional study was conducted from March 2024 to
October 2024 in Limu Seka Woreda of Jimma zone to isolate and identify Staphylococcus
aureus from milk samples and assess its antimicrobial resistance pattern and identify risk
factors associated with mastitis. A total of 216 Dairy cows milk samples were collected
with proportional sampling techniques. The overall prevalence of mastitis at cow level was
118/216(54.62%) with 38.29 % and 59.17 % of clinical and subclinical mastitis
prevalence, respectively. From a total of 864 quarters, examinations of udder, milk and by
CMT test, 13.82 % (26/188) and 25.44% (172/676) were affected by clinical and sub
clinical mastitis, respectively. In this study, the subclinical mastitis was higher than
clinical mastitis
