The present study was designed to determine the prevalence of mastitis in buffaloes and antibiotics sensitivity profiles of isolates. Milk samples collected from 50 dairy buffaloes were tested for subclinical mastitis using Surf Field Mastitis Test (SFMT) and all milk samples were processed for isolation and identification of pathogens. Antibiotics sensitivity profiles of isolates was determined by the disc diffusion method on Mueller-Hinton agar. The over all percent prevalence of sub clinical mastitis were 54/172 (27%), clinical mastitis 8/172 (4%) and blind quarters 20/172 (10%) in buffaloes recorded. Incidence was higher in hindquarters. The percentage of incidence was maximum (39.8%) in animals with the involvement of single quarter. Among the isolates, Staphylococcus aureus had the highest (48%) frequency. Antibiogram analysis of gentamycin, ciprofloxacin, chloramphenicol, cephalothin, sulfa-trimethoprim, amoxycilline, lincomycin, and oxytetracycline showed that each was responsive 90% to isolates. Novobiocin, erythromycin showed sensitivity between 80 to 90%. The sensitivity values for ampiclox and penicillin G were less than 80 %.
