Abstract

We studied the lipophilic microbiota of the external ear canals of 332 animals (264 dogs and 68 cats), with and without otitis externa, over an 11-year period from 1988 to 1999. Malassezia pachydermatis was isolated from 62.2% and 50% of dogs with and without otitis externa, respectively, and from 41.2% and 17.6% of cats with and without otitis externa, respectively. In the group of animals studied for lipid-dependent species, these yeasts were isolated from 4.5% of dogs with otitis externa and from 23.1% and 8.9% of cats with and without otitis externa, respectively. M. sympodialis and M. furfur were isolated from cats and M. furfur and M. obtusa from dogs. Our findings show that lipid-dependent Malassezia species may contribute to the etiology of otitis externa in dogs and cats.

摘要

在1988年至1999年的11年期间，我们研究了332只动物（264只狗和68只猫）外耳道的亲脂性微生物群，这些动物有或没有外耳炎。厚皮马拉色菌分别从62.2%患有外耳炎的狗和50%没有外耳炎的狗中分离出来，分别从41.2%患有外耳炎的猫和17.6%没有外耳炎的猫中分离出来。在研究脂质依赖性物种的动物组中，这些酵母菌分别从4.5%患有外耳炎的狗、23.1%患有外耳炎的猫和8.9%没有外耳炎的猫中分离出来。合轴马拉色菌和糠秕马拉色菌从猫中分离出来，糠秕马拉色菌和钝形马拉色菌从狗中分离出来。我们的研究结果表明，脂质依赖性马拉色菌种可能在犬猫外耳炎的病因学中起作用。
