In this study, 250 lactating cows are tested using standard procedures. Prevalence of mastitis at cow level was 66.0% (165/250), out of which 26.06 % (43/165) and 75.30 % (122/165) were clinical and subclinical, respectively. The quarter level of prevalence was 66.0% (660/1000); from this the clinical and subclinical forms were 26.06% (172/660) and 73.93% (488/660), respectively. The data revealed that Staphylococcus aureus was the commonest organism in mastitis cases, being implicated in 70.30% cases, and Streptococcus agalactiae (5.45%) continues to be a prevalent pathogen followed by S.epidermis (4.24%), Proteus sp (3.63%), Bacillus sp (2.42%), Streptococcus uberis (2.42%), E.coli (1.81%) and Micrococcus sp (8.48%). In addition, Str. agalactiae and S. aureus were more frequently associated with clinical mastitis than sub-clinical case, while the infection rates of other bacteria were similar. In conclusion, this study revealed the importance of mastitis and associated bacterial pathogen in the study area.
