东南亚青年人群中马拉色菌菌种构成分析

目的：研究部分东南亚国家青年人群中马拉色菌菌种构成。方法采集285名青年人（分别来源于中国、尼泊尔、印度、巴基斯坦）面部正常皮肤及皮损区标本，接种于 Leeming ＆amp; Notman 培养基后进行培养分离，生化及形态学方法鉴定到种。结果共分离出8个菌种，共计501株马拉色菌，以球形马拉色菌为主，占40.5℅（203/501），其次为合轴马拉色菌19.0℅（95/501）、糠秕马拉色菌16.0℅（80/501）、限制马拉色菌11.0℅（55/501）、斯洛菲马拉色菌6.2℅（31/501）等。各国家间未见明显的地理学差异。结论东南亚地区青年正常人群及马拉色菌相关疾病患者中的主要菌种为球形马拉色菌。

Malassezia species constitution in youth from some countries of Southeast Asia

Objective To investgate the distribution of Malassezia microflora in youth from some countries of Southeast Asia. Methods Two hundred and eighty-five volunteers came from China,Nepal,India and Pakistan were included,which were healthy volunteers or patients related with Malassezia species. The samples were collected from normal skin of face or lesions skin and cul-tured on Leeming ＆amp; Notman mediums. The isolates were identified to species through physiological and morphological characteris-tics. Results Eight species were identified out from 501 isolated strains,mainly included 203 strains（40. 5℅ ）of M. globosa ,95 strains（19. 0℅ ）of M. sympodialis ,80 strains（16. 0℅ ）of M. furfur ,55 strains（11. 0℅ ）of M. restricta and 31 strains（6. 2℅ ）of M. slooffiae . There were no obvious geographical differences between these four countries. Conclusions The most frequent-ly isolated species were M. globosa in youth from some countries of Southeast Asia,which were healthy volunteers or patients related with Malassezia species.
