目的了解湘西自治州农村人群和腹痛、腹泻患者人芽囊原虫的感染情况。方法对湘西凤凰县农村人群和在湘西自治州疾控中心寄生虫病室就诊的腹痛、腹泻患者收集便样,采用碘液涂片检查人芽囊原虫。结果共检查1 783人,人芽囊原虫阳性328人,阳性率为18.45%。其中农村人群粪检11个村1 439人,人芽囊原虫阳性226人,阳性率为15.71%;门诊腹痛、腹泻患者粪检344人,人芽囊原虫阳性102人,阳性率为29.65%,2者差异有统计学意义(χ2=35.97,P<0.05);男女间感染率差异无统计学意义(χ2=0.001,P>0.05);农村人群以青壮年为高,感染率为22.16%,而门诊患者以>5～10岁儿童为高,感染率为43.00%;土家族、苗族感染率分别20.67%、19.11%,2者无统计学意义,而汉族低于前2者为13.79%,差异有统计学意义(χ2=8.91 P<0.05);在学龄前儿童、学生、职员、农民人群中,以农民为高,感染率为21.19%;城、乡人群感染率分别为15.71%和19.35%,差异无统计学意义(χ2=3.07,P>0.05)。湘西自治州农村人群感染率最低的村为7.35%,最高的村为33.33%。结论湘西自治州人群人芽囊原虫感染率较高,人芽囊原虫是腹痛、腹泻患者的主要病因之一。
Objective To understand the infection status of Blastocystis protozoan in rural population and patients with abdominal pain and diarrhea in Xiangxi Autonomous Prefecture. Methods Stool samples and diarrhea were collected from the rural population in Fenghuang County in western Hunan Province and in the parasite ward of the CDC in Xiangxi Autonomous Prefecture. Results A total of 1 783 people were examined, and 328 were positive for Blastocystis. The positive rate was 18.45%. Including rural population fecal seizure of 1 439 11 people, Blastocystis positive 226, the positive rate was 15.71%; outpatient abdominal pain, diarrhea in patients with fecal examination 344 people, Blastocystis positive 102, the positive rate was 29.65% There was no significant difference between male and female (χ2 = 0.001, P> 0.05). The rural population was young and middle aged, the infection rate was 22.16% While outpatients were> 5 to 10 years old children, the infection rate was 43.00%; Tujia and Miao infection rates were 20.67%, 19.11%, two were not statistically significant, while the Han was 13.79% lower than the previous two, The difference was statistically significant (χ2 = 8.91 P <0.05). Among the preschool children, students, staff members and farmer population, the infection rate was 21.19%; the infection rates in urban and rural areas were 15.71% and 19.35 %, The difference was not statistically significant (χ2 = 3.07, P> 0.05). In Xiangxi Autonomous Prefecture, the lowest prevalence among rural population was 7.35% and the highest was 33.33%. Conclusion The prevalence of Blastocystis infection is high in the population of Xiangxi Autonomous Prefecture. Blastocystis protozoa is one of the main causes of abdominal pain and diarrhea.
