Abstract

The objective of the present study was to analyze the occurrence of methicillin-resistant Staphylococcus aureus (MRSA) from cattle and buffaloes with clinical or subclinical mastitis in Uttar Pradesh, India. Out of total 125 mastitic milk sample collected from clinical and subclinical cases of mastitis from cows (109), buffaloes (16), S. aureus was isolated from only 52 samples showing overall incidence of 41.6%. The incidence of S. aureus was higher (56%) in clinical mastitis than in subclinical (20%). A very high percent of isolates were resistant to cotrimoxazole (63.46%), followed by streptomycin (57.69%), gentamicin (55.76%), cephalexine (42.30%), amoxycillin (38.46%) and erythromycin (36.53%). S. aureus isolates were analyzed by PCR for the presence of mecA gene. The presence of mecA gene considered as a molecular marker of methicillin resistance and was detected only in 5 (9.61%) of 52 S. aureus isolates by PCR. The continuous epidemiological studies for antimicrobial resistance patterns of MRSA isolated from animals would be an important measure in detecting emergence and spreading of antibiotic resistance.
