Abstract

Malassezia (M.) is a member of normal mycobiota in warm-blooded vertebrates. Increased humidity is likely to be crucial in this infection. We studied the proportion of the species infected in dog during summer of Korea. Fifty samples were analyzed by PCR-RFLP and direct sequencing from June 2006 to October 2006. The study showed that lipid-dependent species was main pathogen (M. furfur; 86%, M. obtusa; 10%) while M. pachydermatis (4%) has only small portion. This result suggests that Malassezia infection has endemic characters that can be affected by the climate (temperature and humidity) in dogs.

Malassezia 종은 온혈 척추동물의 정상 미생물총을 구성하며, 개에서는 비지방친화성인 M. pachydermatis가 주로 감염을 유발하는 것으로 알려져 있다. 본 연구는 습도가 높은 한국의 여름 동안 개에 감염을 일으킨 말라세지아종의 분포를 조사하기 위해 실시되었다. 2006년 6월부터 10월까지 총 50개의 샘플을 채취하여 배양한 후 PCR-RFLP와 direct sequencing을 통해 분석하였다. 조사 결과 지방친화성 종인 M. furfur와 M. obtusa가 전체 96%를 차지하였으며, M. pachydermatis는 4%만을 구성하였다. 이 결과는 기후에 따라 감염을 일으키는 Malassezia 종에 차이가 있을 수 있음을 보여준다.
