Abstract

The present study aimed to determine the prevalence of Staphylococcus aureus in mastitis milk from bovines. Mastitis milk samples from cattle (24) and buffaloes (26) were collected in and around Ludhiana. Out of 50 samples, 18 isolates of S. aureus (10 from buffaloes and 8 from cattle) were isolated and identified based on cultural, morphological, and biochemical characteristics. The prevalence of the isolates was higher in buffaloes (55.55%) than in cattle (44.44%). Antibiotic susceptibility testing revealed that 44.44% of the isolates were resistant to more than six antibiotics, and 83.33% showed multidrug resistance, i.e., resistance to three or more antibiotics.
