ABSTRACT
Subclinical mastitis is multifactorial inflammation of mammary glands in dairy animals, resulting in changes in milk quality, milk production, and economic losses to dairy farmers. It mainly occurs due to non-contagious environmental bacterial species. In Pakistan, it is the major disease of different dairy animals including bovines. However, only a little information is available about bacterial profile of the disease. A cross-sectional study was conducted to find the Etio-prevalence of bacterial species causing subclinical mastitis in a cohort of buffaloes at Khyber Pakhtunkhwa. 120 quarter samples were collected from suspected buffaloes in selected areas of Peshawar, Charsadda, Mohmand Agency, and Dara Adam Khel. Initially, California Mastitis Test was performed for screening of positive samples. Afterward, the bacterial profile was confirmed through biochemical testing. The quarter wise prevalence of subclinical mastitis was 25%. Within this, contribution of Gram-negative bacteria was 68% and that of Gram-positive bacteria was 32%. Among 30 positive samples, percentage prevalence of different bacterial species was: E.coli (37%), S. aureus (23%), Pseudomonas (20%), Streptococcus (10%), Proteus (7%) and Salmonella (3%). The study reported high percentage of E. coli in cases of subclinical mastitis. It may be due to transfer of pathogen from cow to buffaloes and from the environment in herds of mixed farming. The study results may be helpful in developing the strategic policies against the control of disease.
