【摘要】 目的了解饮食习惯与蠕形螨感染的关系。方法以本科医学生为研究对象,采用透明胶纸挤粘法采集鼻唇沟及鼻尖部位蠕形螨,显微镜下检测虫体,发现成虫、幼虫或者虫卵均为阳性。结果 254名学生蠕形螨总感染率为18.50%,其中单一毛囊蠕形螨感染率为14.96%,占总感染数的80.85%;单一皮脂蠕形螨感染率为2.36%,占总感染数的12.77%;两种蠕形螨混合感染率为1.18%,占总感染数的6.38%。农村学生感染率为20.70%,城市学生感染率为10.71%,城市与农村学生感染率差异无统计学意义(P>0.05)。喜欢食用咸香辛辣食物者感染率为16.92%,不喜欢食用咸香辛辣食物者感染率为20.16%,两种饮食习惯者感染率差异无统计学意义(P>0.05)。结论人面部蠕形螨感染虫种主要是毛囊蠕形螨,蠕形螨感染与饮食习惯无关。更多还原

【Abstract】 Objective To learn the relationship between the dietary habits and Demodex Humanis infections. Methods Using transparent tape,try to collect demodexes from the nasolabial sulcuses and nosaltips of undergraduate medical students. Any findings of adults,larvae and eggs would be taken as positive. Results Total infection rate of demodex among students was 18. 50%,within which 80. 85%were caused by D. folliculorum with an infection rate of 14. 96%. The infection rate of D. brevis was 2. 36%,taken up 12. 77% of total infections. Mix infection rate caused by both of these two demodexes was 1. 18%,accounting for 6. 38% of total infections. The infection rate of rural students was 20. 70% and that of city students was 10. 71%,but there was no statistically significant between them( P > 0. 05). The infection rate of people who like salty and spicy food was 16. 92% and that of people who didn’t like salty and spicy food is 20. 16%. There was no statistical significance between them( P > 0. 05). Conclusion Human facial demodex infections are mainly caused by D. folliculorum. There is no relationship between the dietary habits and Demodex Humanis infections.更多还原
