Online published on 2 April, 2016. Abstract The study included 44 dogs with clinical signs specific for otitis externa. The microbiological tests showed that 35 isolates with typical characteristic of genus S. aureus (79%). No isolate from 4 samples and isolate of gram negative bacteria and yeast from 5 dogs were eliminated from this study. The most active antimicrobial agents against Staphylococci isolated from otitis externa of dogs were Cephalexin and Penicillin. The organism is much resistant to Azithromycin (7.78%), Ciprofloxacin (55.56%), Gatifloxacin (44.44%) and Piperacillin (55.56%). Based on antimicrobial susceptibility, all the animals were treated with Tab. Cephalexin 25 mg/kg b.w.t. BID orally, Tab. Prednislone 1 mg/kg b.wt. orally for seven days and Otic drops twice daily for 7 days. After a week, all the animals showed marked clinical improvement in the form of reducing signs of erythema, swelling, otohhroea, pain and itch.
