Online published on 20 November, 2017. Abstract The study was undertaken on 91 nasal swab, lung tissue and tracheal swab samples from clinically sick ovine and caprine for isolation, identification and antibiogram of bacterial species. A total of 89 bacterial pathogens were isolated from 91 samples of sick animals which included Staphylococcus spp. (44.94%), Bacillus spp. (7.87%), E. coli (25.84%), Pseudomonas spp. (12.36%), Mannheimia haemolytica (4.5%) and Klebsiella spp. (4.5%). The antibiotic sensitivity pattern of Staphylococcus spp. revealed 100% sensitivity to Ampicillin and Amoxicillin, while found resistant to Streptomycin, Penicillin-G, Erythromycin, Amikacin, Bacillus spp. were sensitive to Chloramphenicol, Enrofloxacin and Gentamicin and E. coli was sensitive to all antibiotics that were tested, Pseudomonas spp. indicated highest sensitivity towards Gentamicin and resistant to Erythromycin, Tetracycline and Amoxicillin. M. haemolytica showed sensitive to Gentamicin, Ceftriaxone and Enrofloxacin while resistant to Cephalexin, Ampicillin and Tetracycline and Klebsiella spp. were sensitive to Chloramphenicol, Ceftriaxone and Enrofloxacin. The present study shows the relationship between indiscriminate use of antibiotics and drug resistance. Top Keywords Antibiogram, bacterial pathogen, respiratory infection, small ruminant. Top |
