Abstract:
Mastitis is a multi-etiologic disease of the mammary gland characterized mainly by reduction in milk production and milk quality due to intramammary infection by pathogenic bacteria. Nearly 83% of lactating dairy cows in India are infected with mastitis with various degree of inflammation. In this study, we determined differential count of somatic cell count, bacterial load and presence of S. aureus in milk collected from healthy, sub-clinical (SCM) and clinical mastitis (CM) Karan Fries cows. On the basis of SCC and CMT score milk was categorized into Healthy, SCM and CM. The SCM and CM milk samples were positive for S. aureus on MSA and Baird Parker Agar media while healthy milk samples were negative for S. aureus.
