摘　　要：目的了解独龙族小学生肠道寄生虫感染情况,为防治工作提供依据。方法采用改良加藤厚涂片法查肠道蠕虫卵;直接涂片法查肠道原虫;透明胶纸肛拭法查蛲虫;改良抗酸染色法查稀便中的隐孢子虫卵囊。结果共检查239人,感染211人,总感染率为88.28%,共查到9种寄生虫,各种寄生虫感染率分别为:鞭虫71.55%,蛔虫66.95%,钩虫9.21%,微小内蜒阿米巴3.77%,蓝氏贾第鞭毛虫2.51%,哈氏内阿米巴1.67%,溶组织阿米巴、结肠阿米巴和布氏嗜碘阿米巴均为0.42%。钩虫虫种为美洲钩虫,蛲虫和隐孢子虫均未检出。蛔虫、钩虫和鞭虫的感染度均以轻度感染为主。性别、年级和民族构成比无统计学差异(P均>0.05);来源于龙元村委会的学生感染率最高,为95.45%(21/22),马库学生的肠道感染率最低,为30.00%(3/10),各地学生肠道寄生虫感染率差异有统计学意义(P<0.01)。结论独龙族小学生肠道寄生虫感染率较高,当地卫生环境差、不良的卫生习惯和学校的肠道寄生虫病防治工作缺乏是主要原因。Objective To investigate the epidemic status of intestinal parasites in the students of Drung Nationality fromprimary schools, Yunnan Province in order to provide scientific evidence for its prevention and treatment. Methods ModifiedKato-Katz thick smear was applied to detect helminth eggs, the iodine-stained direct smear method for intestinal protozoa, thecellophane tape method pinworm eggs, and the modified acid fast staining method for Cryptosporidium oocysts in loose stools.Results A total of 239 students were investigated, and 211 of them（88.28%） were positive. The observed 9 species ofintestinal parasites included Trichuris trichiura（71.55%）, Ascaris lumbricoides（66.95%）, hookworm（9.21%）, Amoeba limax（3.77%）, Giardia lamblia（2.51%）, Endamoeba hartmanni（1.67%）, Amoeba histolytica（0.42%）, Amoeba coli（0.42%） andIodamoeba butschlii（0.42%）. The species of hookworm was Necator americanus. No ascaris, oxyurid and Cryptosporidiumoocysts were detected. The infections of roundworm, hookworm and whipworm were mild. There was no significant differencesin constituent ratios of gender, grade and nationalities（P〉0.05）. The students fromLongyuan Village had the highest infectiousrates（95.45%, 21/22）, and those from Maku Village had the lowest rates（30.00%, 3/10）. Significant difference was seen in theinfectious rates among the pupils frome different areas（P〈0.01）. Conclusion The pupils of Drung Nationality havecomparatively higher infectious rate of intestinal parasites. The main reasons might be due to the poor environmental hygiene,unhealthy living habits, and lack of prevention and control measures about the disease in the schools.
