摘要 用透明带法观察蠕形螨在体面部的寄生,逸出及其在体外的存活能力,结果表明:毛囊蠕形螨(Demodexfolliculorum,D.f.)主要以颚体朝向毛囊底部寄生,且常常有多要群居现象,而皮脂蠕形螨,(DemodexbrevisD.b.)一般为单条独居生活,两种人体蠕形螨昼夜均可主动爬出毛囊口出现在皮肤表面,D.f.以白天10:00~18:006国逸出高峰:D.b.则以夜间22:00~2:00逸出最 Using cellophane method, the parasitism and excursion of vermiform mites on human faces and their survival in vitro were observed. The results showed that Demodex folliculorum (D.f.) chiefly parasitized with their jaws towards the bottom of hair follicle and often lived in crowds, while Demodex brevis (D.b.) usually parasitized singly. Both species of mites could crawl out from the follicular orifices actively, appearing on the surface of skin during day and night. However, the peak excursion time of D.f. was from 10∶00 to 18∶00, while D.b. was from 22∶00 to 02∶00. Moreover, the mites moved more actively and lived longer in vitro. The cellophane method will be more valuble in the epidemiological survey of human vermiform mites and their biologic study.
