Online published on 20 November, 2017. Abstract Nasal swabs of twelve calves affected with respiratory disease were examined for common bacterial pathogens viz. Pasteurella spp., Staphylococcus spp., Streptococcus spp. and E. coli. Coagulase positive Staphylococcus aureus was isolated from 6 of 12 calves (50.0%). E. coli and mixed infections of coagulase positive and negative Staphylococcus aureus and E. coli were isolated from 2 (16.67%) and 4 (33.33%) calves, respectively. The isolates were tested for susceptibility to agents, all isolates showed higher susceptibility to Ceftiofur sodium followed by Enrofloxacin, Amoxicillin/Clavulanic acid and Doxycycline than to other antibiotics. However, Nitrofuratoin showed nil effect on any of isolated pathogens. The isolates were less susceptible to Tetracycline and Sulfamethoxazole/Trimethoprim combination.
