This study was brought to the Veterinary Faculty of the University of Uludağ and in the clinical examination 54 dogs suspected of otitis externa were taken ear spots, microorganisms were isolated and identified, with the aim of determining the antibiotic sensitivity of bacteria. Of the fifty-four samples, 52 (96.29) were reproduced. Of the fifty-two samples, 12 different bacteria, 5 different fungi and 2 different mammal reproductions were detected. 20 of the products (38.46) were isolated in the form of pure culture and 32 (61.53) in the form of mixed culture. While Staphylococcus aureus (%55.76) is the most isolated factor, it is respectively Aspergillus fumigatus (%17.30), Malassezia pachydermatitis (%17.30), Coagulase negative Staphylococcus spp. (% 17.30), Candida spp. (%11.53), Epidermophyton spp. (9.61%) Penicillium spp. (7.6%) and Bacillus spp. and %5. The Citrobacter spp. (5.76 %), Microsporum spp. (5.76%), Klebsiella spp. (3.8%) and Streptococcus spp. (%3.84), Escherichia coli (%3.84), Micrococcus spp. (3.84 %), Trichophyton spp. (3.84 %), Pseudomonas spp. (%1.92), Corynebacterium pyogenes (%1.92), Enterobacter spp. (%1.92), Acinetobacter spp. It was 1.92% followed. Antibiotic sensitivity to the isolated bacteria was tested and the two most effective antibiotics were Sulfamethoxazole/Trimethoprim and Neomisin. The least effective antibiotic was found as rifampicin. ●●● S U M M A R Y Determination and Antimicrobial Susceptibility of Microorganisms Isolated from Otitis Externa with Dogs In this study, 54 ear swabs taken from suspected of otitis externa with dogs in Uludag University Faculty of Veterinary Medicine. Microorganisms are isolated and identified. We determined the susceptibility of bacteriae to antibiotics. Microorganisms isolated from 52 samples of 54 ear swabs. 12 bacteriae, 5 fungi, and 2 yeast isolated from 52 samples. The microorganisms were isolated in pure culture from (38.46 ) samples and were isolated in mixed culture from (61.53) samples. Staphylococcus aureus (55.76%) were most commonly isolated and respectively, Aspergillus fumigatus ( 17.30%), Malassezia pachydermatitis ( 17.30%) , coagulase -negative Staphylococcus spp. ( 17.30 % ) , Candida spp. ( 11,53% ) ,Epidermophyton spp. ( 9.61 % ) , Penicillium spp . (7.69%) , Bacillus spp. (5.76 % ) , Citrobacter spp. (5.76% ), Microsporum spp. (5.76 % ) , Klebsiella spp. (3.84%) , Streptococcus spp. ( 3 ) 84%) , Escherichia coli (3.84%) , Micrococcus spp. (3.84%) , Trichophyton spp. (3.84%) , Pseudomonas spp. ( 1.92 % ) , Corynebacterium pyogenes ( 1.92 % ) , Enterobacter spp. ( 1.92 % ) , Acinetobacter spp. ( 1.92 % ) were isolated and identified. We determined sulfamethoxazole/Trimethoprim and neomycin were the most effective antibiotics. Rifampicin wasfound to be the least effective.
