Antimicrobial susceptibility of bacterial species identified from mastitic milk samples of camel

摘要

Twelve different antibiotics were used against bacterial species to record their sensitivity. The antibiotics were amikacin, amoxicillin, ampicillin, cephalexin, chloramphenicol, erythromycin, gentamycin, kanamycin, neomycin, ofloxacin, sulphamethoxazole trimethoprim and tetracycline. The species that showed sensitivity to amikacin were:?Corynebacterium pyogenes?(100%),?Bacillus cereus(91.6%),?Staphylococcus aureus?(85.7%) and?Pseudomonas aeruginosa?(66.6%). Whereas,?B. cereus?(100%),?C. pyogenes?(70.5%),?Micrococcus luteus?(78.5%),Pasteurella haemolytica?(100%),?Pasteurella multocida?(100%),?P. aeruginosa(72.2%) and?S. aureus?(100%) were observed to be highly sensitive to tetracycline. The species?S. aureus?(100%),?P. aeruginosa?(100%) and?B. cereus?(91.6%) were highly sensitive to sulphamethoxazole trimethoprim.? The species?Escherichia coli(100%),?M. luteus?(100%),?P. haemolytica?(92.8%) and?P. multocida?(93%) showed sensitivity to chloramphenicol. Moreover,?P. haemolytica?(100%),?P. multocida(100%),?C. pyogenes?(70.5%) and?S. aureus?(85.7%) were sensitive to neomycin. The other species recorded as highly sensitive to cephalexin were:?C. pyogenes(100%),?P. multocida?(80%),?P. aeruginosa?(72.2%) and?S. aureus?(85.7%), respectively.
