A total of 300 milk samples from buffaloes were evaluated for mastitis and incidence of E. coli. Overall, 157 milk samples () were positive for mastitis and out of these positive isolates, 27 bacterial isolates ( %) were identified as E. coli. All the 27 isolates of E. coli were tested for in vitro sensitivity towards 15 antibacterial drugs. The highest resistance was attributed towards antibiotic Kanamycin followed by Cefotaxime, Trimethoprim, Cefotaxime + Clavulanic acid, Amoxycillin, Cefixime, Tetracycline, Ampicillin + Salbactum, Amikacin, Chloramphenicol, Nitrofurantoin, Gentamicin, Cefoperazone, Ceftriaxone and Ciprofloxacin. Simultaneously resistance to 2 to 9 antibacterial agents, was observed in all 27 (100%) isolates. | Isolation of E. coli from bovine mastitis and their antibiotic sensitivity pattern
