对佳木斯大学2013级印度留学生291人和本地学生314人进行面部蠕形螨感染情况调查,采用挤刮涂片法收集样品,滴加甘油后进行镜检,采用SPSS 19.0软件进行统计学分析。留学生中男性感染率为16.4%(34/207),女性感染率为9.5%(8/84);本地学生中男性感染率为49.0%(71/145),女性感染率为18.9%(32/169),两组学生男性感染率之间差异有统计学意义(χ~2=43.14,P<0.05);所有留学生和男性本地学生均以单纯毛囊蠕形螨(Demodex folliculorum)感染为主,其次是单纯皮脂腺蠕形螨(Demodex brevis)和混合感染,但女性本地学生则以混合感染为主;另外,本地学生面部皮肤有症状者蠕形螨感染率(68.2%,60/88)明显高于无症状者(19.0%,43/226)(χ~2=69.43,P<0.05)。 A total of 291 Indian students at 2013 Jiamusi University and 314 local students were investigated for vermiform mite infection. Samples were collected by squeegee smear method and microscopically examined after dropping glycerol. The data were analyzed by SPSS 19.0 software. The rate of male infection among international students was 16.4% (34/207) and that of female students was 9.5% (8/84). Among male students, 49.0% (71/145) were male and 18.9% (32 / 169). There was a significant difference in male infection rates between the two groups of students (χ ~ 2 = 43.14, P <0.05). All local students and male local students were infected with Demodex folliculorum, (Demodex brevis) and mixed infections, but local female students were mainly mixed infections. In addition, the prevalence of Demodex mites (68.2%, 60/88) was significantly higher in local students with facial skin symptoms than those with Demodex Asymptomatic (19.0%, 43/226) (χ ~ 2 = 69.43, P <0.05).
