目的了解上海市不同人群人芽囊原虫感染情况。方法在上海市6个区收集居民新鲜粪便,采用Ringer溶液37℃恒温条件下培养人芽囊原虫,计算人芽囊原虫感染率。结果检查居民2 984人,人芽囊原虫阳性者88人,感染率2.95%。上海市各区人群感染率间差异无统计学意义(χ~2=9.90,P>0.05);青浦区男性感染率为5.56%,女性感染率1.57%,差异有统计学意义(χ~2=5.38,P<0.05),其他5个区男、女性感染率差异无统计学意义(χ~2=0.08～0.54,P均>0.05);农民感染率为6.87%,与其他职业人群比较差异有统计学意义(χ~2=18.57,P<0.05)。结论上海市人群对人芽囊原虫普遍易感,以农民感染率最高。体外培养法敏感性较高.可用于人芽囊原虫感染的流行病学调查。
Objective To understand the infection of Blastocystis in different populations in Shanghai. Methods Fresh feces of residents were collected in 6 districts of Shanghai. The Blastocystis hominis was cultured under the constant temperature of 37 ℃ in Ringer’s solution to calculate the infection rate of Blastocystis. Results A total of 2 984 inhabitants were tested, while 88 were positive for Blastocystis sp., With an infection rate of 2.95%. There was no significant difference in infection rates among all districts in Shanghai (χ ~ 2 = 9.90, P> 0.05). The male infection rate was 5.56% and the female infection rate was 1.57% in Qingpu District (χ ~ 2 = 5.38 , P <0.05). There were no significant differences in the infection rates of males and females among the other five districts (χ ~ 2 = 0.08-0.54, P> 0.05). The infection rate of peasants was 6.87%, which was statistically different from other occupational groups Significance (χ ~ 2 = 18.57, P <0.05). Conclusion The population of Shanghai is generally susceptible to Blastocystis protozoa, with the highest rate of peasant infection. In vitro culture method is highly sensitive and can be used for epidemiological investigation of human Blastocystis infection.
