摘　　要：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 investigate the prevalence of Blastocystis hominis infection in Xiangxi rural area and the patients with Abdominal pain and diarrheal. Methods The fecal samples were collected from Fenghuang rural area residents and the patients with abdominal pain and diarrheal. The fecal samples were stained with Iodine and examined by microscope. Results A total of 328 out of 1783 fecal specimens were positive with a prevalence of 18.45%. Infection rates of Blastoeystis hominis in rural area residents and patients with abdominal pain and diarrheal were 15.71% （226/1439） and 29.6% （102/344） , respectively, there were significant differences between different population （ X2 = 35.97, P 〈 0. 05）. However, There was no significant difference between male and female （X2 = 0. 001, P 〉 0. 05 ）. In out - patients individuals of ages 〉 5 - 10 had highest infection rate, 43.00%, （X2 = 13.89, P 〈0. 01）, while young adults had highest infection rate in rural area, 22. 16%, （X2 = 14. 10, P 〈0. 01）. The infection rates of Tujia, Miao and Han were20.67%, 19. ll%andl3.79%, respectively, While no significant difference between them （ X2 = 8. 91, P 〈 0. 05 ）. In terms of occupation, farmer had the highest infection rate, 21.19% （X2 = 8. 02, P 〈 0. 05）. Furthermore,The infection rates of urban and rural residents were 15. 71% and 19. 35%, respectively. While no significant was found in prevalence rates between them （X2 =3. 07, P 〉0. 05）. In Xiangxi rural area, the village with the highest infection rate was 33.33%, while the lowest was 7.35%. Conclusion The rate of Blastocystis hominis infection in Xiangxi Autonomous Prefecture is high. Blastocystis hominis infection is one of the major cause of abdominal pain and diarrheal.
