引言人体蠕形螨病分布相当普通,国外早有报导,但比较系统的生物学描述及种属鉴定是近十年的报导,如Nutting(1965)报导了寄人体两种蠕形螨的形态区别及所致病理变化等。1970(Akblotova)报到了69例,其中毛囊蠕形螨(Demodex follculorum)25例,脂蠕形螨(D·brevis)16例,混合感染28例。Nutting(1976)又对上述两种病原体所致病变加以描述。相德超(1979)报导了自1964—1977所积累的200例。其他为山东,山西也都有积累的病例资料。河南、湖南、广西、黑龙江、贵州等地亦有发现。内蒙地区于1978年首次发现后,继之在皮科门诊不断有患者。看来、过去是由于疏忽而未
Introduction Demodex distribution is very common in humans. It has long been reported in foreign countries. However, more systematic biological descriptions and species identification have been reported in recent ten years. For example, Nutting (1965) reported the morphological differences between two demodicides And the resulting pathological changes. 1970 (Akblotova) reported 69 cases, of which 25 were Demodex follculorum, 16 were D · brevis and 28 were mixed infections. Nutting (1976) described the pathogenic lesions caused by these two pathogens. Xiang-Chao (1979) reported the accumulation of 200 cases since 1964-1977. Other for Shandong, Shanxi also have accumulated case information. Henan, Hunan, Guangxi, Heilongjiang, Guizhou and other places have also been found. Inner Mongolia was first discovered in 1978, followed by patients in the Pico clinic. It seems that the past was due to negligence
