摘　　要：目的通过对在校学生面部蠕形螨感染情况的调查，了解蠕形螨感染与致病的关系，为采取有效措施预防群体蠕形螨感染提供依据。方法用刮取法和透明胶带粘贴法采集受检者两侧鼻翼处分泌物并在显微镜下检查，阳性者计数并进行虫种鉴定。结果共榆查928名在校学生，阳性85人，感染率9．2％（85／928）。男性中阳性36人，感染率为10．2％（36／353），女性中阳性49人，感染率为8．5％（49／575），男女感染率差异无统计学意义（P〉0．05）。蠕形螨感染中以毛囊蠕形螨感染为主；轻度感染率高于中、重度感染（P〈0．01）；刮取法检出率明显高于粘贴法（P〈0．05）；聚居者感染率高于家庭生活者（P〈0．01）；不同肤质的人蠕形螨感染率差异无统计学意义（P〉0．05）。结论在校学生蠕形螨感染较为普遍，应加强聚居学生蠕形螨感染的群防群治工作。Objective To survey facial Demodex infestation in students in order to investigate the pathogenic fac- tors of Demodex infections and provide basis for the effective prophylaxis of Demodex infection in population. Methods Secretions were collected from nosewings of the subjects by scraping method and scotch tape adhesion for microscopic ex- amination, with the number of positive subjects counted and pest species identified. Results Of the 928 students exam- ined, there were 85 positive cases, with an infection rate of 9.2% （85/928）. There were 36 positive cases among the males, with an infection rate of 10.2% （36/353） , and 49 positive cases among females, with an infection rate of 8.5% （ 49/575 ）. The infection rates between males and females showed no statistical difference （ P 〉 0.05 ）. The Demodex in- festation was chiefly due to Demodex folliculorum; There was a higher prevalence of mild infection than that of moderate infection （P 〈 0.01 ） ; Of the two detection methods, scraping method had higher detection rate than scotch tape adhesion （ P 〈 O. 05 ） ; People who live in aggregation had higher infection rate than those living at home （ P 〈 0.01 ） ; There was no statistical significance between the differences in skin texture （ P 〉 0.05 ）. Conclusion Demodex infection is com- mon among students on campus, who are characteristic of aggregated residence. Prophylaxis and treatment of Demodex infection should be strengthened among students who live in aggregation.
