The hair follicle mites Demodex folliculorum and D. brevis are the most common permanent ectoparasites of Man. Ordinarily they are harmless to their human host and appear to be of no medical significance. We present, however, an unusual finding regarding this mite, namely, that in a potassium hydroxide mount of a skin scraping from a mycotic plaque we found numerous Demodex mites containing inside them spores of Microsporum canis. This could mean that the putatively inoffensive Demodex has the potential to ingest various microorganisms that are found in its niche and transport them to other areas of the skin or possibly to other individuals.
毛囊螨,即毛囊蠕形螨和皮脂蠕形螨,是人类最常见的永久性体表寄生虫。通常情况下,它们对人类宿主无害,似乎也没有医学意义。然而,我们在此展示了一项关于这种螨虫的不寻常发现,即在一份来自真菌斑块皮肤刮屑的氢氧化钾涂片标本中,我们发现大量毛囊螨体内含有犬小孢子菌的孢子。这可能意味着,通常被认为无害的毛囊螨有摄取其生存环境中各种微生物并将它们传播到皮肤其他部位或可能传播给其他个体的可能性。
