【摘要】 目的调查广州医学院2001级大学生人体蠕形螨的感染情况,探讨蠕形螨感染与皮肤疾病、宿舍分布的关系。方法采用透明胶纸粘贴法对468名在校大学生蠕形螨感染进行调查,同时观察其面部皮肤状况,询问其所住宿舍状况并记录于调查表内。结果广州医学院2001级大学生468人,检出人体蠕形螨者85人,感染率18.16%。男学生感染率为18.37%(52/283人),女学生为17.84%(33/185人),两者无显著性差异(P>0.05)。从学生来源地看,城镇学生感染率为15.94%(51/320人),农村学生为22.97%(34/148人),两者无显著性差异(P>0.05)。感染者的感染度以每条透明胶纸1～3条虫为多,占87.06%(74/85人)。检获的螨大多为毛囊蠕形螨,占70.59%(60/85人),单一感染皮脂蠕形螨仅15.29%(13/85人),两者混合感染为14.12%(12/85人)。面部有痤疮、毛囊炎或毛囊扩张者蠕形螨感染率均高于面部皮肤正常、有痒感者(P<0.05);有痒感者蠕形螨感染率与面部皮肤正常者无显著性差异(P>0.05)。感染蠕形螨者具有显著的宿舍聚集性(P<0.01)。结论广州医学院2001级大学生人体蠕形螨感染较为普遍。感染大多为毛囊蠕形螨,少数为皮脂蠕形螨及两者混合感染,两种蠕形螨的感染度都属轻度。蠕形螨感染可能是痤疮、毛囊炎或毛囊扩张等皮肤疾病的致病因素之一。蠕形螨感染可以通过同更多还原

【Abstract】 Objective To investigation infection status of human follicle mite s among the local college students and to explore the relationship between human follicle mites infection and dermatosis. Methods 468 local college students wer e selected for the diagnosis of human follicle mites infection using transparent adhesive tape method. Facial skin and dorm of each student was examined and the related current situation was recorded. Results The infection rate of human fol licle mites of the local university student was 18.16%(18.37%in male and 17.84 %in female).The 87.06%(74/85)infected students were found to have 1～3 human follicle mites .In 85 infected students, 60(70.59%) were infected with Demodex folliculorum; 13(15.29%) were infected with Demodex brevis; and 12 (14.12%) we re infected with both. There was no significant difference in the infection rate between male and female (P >0.05). There was no significant difference in the i nfection rate between those people from city or town and rural (P >0.05). The in fection rate of the students who had rulgaris, folliculitis or ectatic folliculu s pili was higher than the normal ones and the students who had itch(P< 0.05). The infection rate of the students who had itch was the same as the normal ones (P >0.05).The infection of human follicle mites had clustering in dormitories(P < 0.01). Conclusions The infection of human follicle mites was common in the loc al college and was likely the cause of dermatosis. The vast majority of the infe ction among the student was caused by Demodex folliculorum. The Demodex mite inf ection might be transmitted through the same dormitories.更多还原
