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 understand the intestinal parasitic infection of primary students in Dulong County and provide basis for prevention and treatment. Methods The modified Kato thick smear method was used to detect intestinal worm eggs; direct smear method was used to detect intestinal protozoa; translucent adhesive tape anal swab was used to examine pinworm; modified acid-fast staining was used to detect cryptococcal oocysts. Results A total of 239 people were examined and 211 were infected. The total infection rate was 88.28%. Nine kinds of parasites were detected. The infection rates of various parasites were 71.55% for whipworm, 66.95% for roundworm, 9.21% for hookworm, 3.77% for amoeba, 2.51% for Giardia lamblia, 1.67% for Entamoeba histolytica, 0.42% for Entamoeba histolytica, Entamoeba histolytica, Hookworm species hookworm, pinworm and Cryptosporidium were not detected. Roundworms, hookworm and whipworm infection are mild infection-based. (P0.05). The highest infection rate was 95.45% (21/22) among the students from Longyuan village committee, the lowest among the students in Ma Ku college, Was 30.00% (3/10). There was significant difference in intestinal parasitic infection among students (P <0.01). Conclusion The prevalence of intestinal parasites in Dulong primary school students is high, the local health environment is poor, bad hygiene habits and the lack of prevention and treatment of intestinal parasites in schools are the main reasons.
