Antimicrobial susceptibility, bacterial organisms, mastitic milk.Abstract
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.
