Antibiotic sensitivity of microbial isolates and therapy of otitis externa in dog

This study aimed to determine the antibacterial sensitivity of various microorganisms’ isolates and evaluate the efficacy of usual therapy in dogs with otitis externa. Of 976 examined dogs, 117 were infected (12%). Ear swabs were inoculated on different media for microbiological examination. The most prevalent microorganism isolated from ear swab was Staphylococcus aureus (35.17%) and Pseudomonas aenaginosa (26.7%). Based on the results, penicillin, erythromycin and gentamycin were highly effective against the isolated bacteria and mycostatin against yeast and fungi. The response to the treatment in this study suggests that early diagnosis with a specific treatment is great importance.
