Abstract

Malassezia spp. was isolated from the skin lesion of a South American Sea Lion (Otaria byronia) in South Korea. Colonies were cream to yellowish with smooth margin on Sabouraud dextrose agar without lipid supplements. Yeast cells were ovoid to cylindrical in shape and budding daughter cells from broad base. We conducted 26s rRNA sequencing to specify the strain of the yeast and found out this isolate highly matched with Malassezia pachydermatis isolated from canine otitis. The pulse therapy of oral itraconazole was very effective in this case. M. pachydermatis has a wide range of host animals but this is the first report in a sea lion in South Korea.

오타리아 물개의 탈모성 피부염에서 Malassezia spp. 를 분리하였다. Sabouraud dextrose agar에서 성장한 집락형태는 유백색에서 황색조로 변연부는 매끄러웠다. 현미경 검경시 형태는 원형에서 실린더형이었고 증식을 지시하는 budding 형이 관찰되었다. 개의 외이염에서 분리한 Malassezia pachydermatis와 비교하기 위해 26s rRNA 염기서열 분석을 실시하여 99.9% 의 일치도를 보였다. Itraconazole pulse therapy는 매우 효과적이었고 재발하지 않았다. 본 증례는 국내 물개에서 발생한 Malassezia 피부염 최초 보고로 판단된다.
