蠕形螨的系统学研究进展

Advances on the research on systematics of Demodex

蠕形螨是一类小型永久性寄生螨，目前已知有140个种和亚种，可寄生于11种目的哺乳动物的毛囊和皮脂腺等部位。蠕形螨具有高感染率和低发病率的特征。随着蠕形螨与人体面部皮肤病关联性的确认．其种群分类与致病关系已引起医学界的关注。该文就蠕形螨的研究历史、形态学分类、DNA标志以及系统发育等研究进展进行综述。

Demodex mites are slender and permanent parasites. Up to now, 140 species or subspecies have been identified, infesting the hair folficles, sebaceous glands and other parts of 11 orders of mammals. The pathogenicity of Demodex has not been universally acknowledged mainly because of its high infection rate yet low incidence rate. Thanks to the recent studies that confirmed the association between Demodex mites and human facial demlatosis, the relationship between the population classification and pathogenicity of Demodex has drawn attention from the medical field. These advances are reviewed in various aspects of Demodex research, including research history, morphological classification, DNA markers arid phylogeny research.
