초록

본 연구는 개 외이염에 대한 enrofloxacin-silver sulfadiazine (Baytril$^{(R)}$ otic, Bayer, USA)의 치료효과를 평가하는 것이다. 24두의 외이염 이환견을 대상으로 처치군에는 바이트릴 오틱을, 대조군에는 증류수를 이도내 7일간 국소투약한 후 7일후에 임상증상, 미생물 및 효모균수를 통해 효과를 비교하였다. 또한 외이염에서 분리된 세균 및 효모균에 대한 바이트릴 오틱의 최소억제농도를 산출하였다. 주요 분리균으로는 Staphylococcus pseudintermedius, Pseudomonas aeruginosa, Proteus spp and Malassezia pachydermatis.이었다. 임상증상의 경감은 81%, 미생물수는 87% 감소하였다. 바이트릴 오틱은 분리된 균에 대한 살균효과가 충분하였고 국소투약에 대한 부작용은 관찰되지 않았다. 따라서 바이트릴 오틱은 개의 외이염 감염에 대한 효과적이며 안전한 제제로 판단된다.

The aim of this study was to evaluate the in vivo and in vitro efficacy of enrofloxacin-silver sulfadiazine (Baytril$^{(R)}$ otic, Bayer, USA) for the treatment of otitis externa in dogs. Twenty-four dogs with otitis externa were included in this double-blinded, randomized study. The experimental group was treated with the Baytril$^{(R)}$ otic and the distilled water was applied to the control group. Both groups were administered each solution twice daily for 7 days and next 7 days off treatment. On days 0, 7 and 14, clinical signs, bacteriological and fungal counts were graded using semi-quantitative scales, respectively. For the evaluation of in vitro efficacy of Baytril$^{(R)}$ otic, we also performed Minimal Inhibitory Concentration (MIC) test by agar dilution method against Staphylococcus pseudintermedius, Pseudomonas aeruginosa and Malassezia pachydermatis. In the experimental group, the sum of clinical scores was decreased 81.0% and microbial scores were significantly reduced 87.0% at days 14, compared with day 0. The results of MIC testing were showed the concentration of enrofloxacin and silver sulfadiazine in Baytril$^{(R)}$ otic is high enough to kill for 3 infectious agents. No adverse reactions were observed in any of the dogs during this study. These results suggest that Baytril$^{(R)}$ otic are efficient and safe treatment for canine otitis externa.
