摘要:   目的 调查腹泻患者中圆孢子虫和隐孢子虫的感染情况及分布特征。 方法  1997~ 2 0 0 0年每年的 3~10月份 ,收集云南省 6个地 (州、市 )所属 7个县 (市、区 )寄生虫病防治试点 378例腹泻患者的粪便 ,进行碘液直接涂片和粪便涂片抗酸染色镜检。 结果  7个县 (市、区 ) 378例腹泻患者的圆孢子虫和隐孢子虫的总感染率分别为 3.97%和5 .2 9% ,其中学龄前儿童的感染率最高 ,圆孢子虫和隐孢子虫的感染率分别为 10 .6 4%和 8.5 1%。圆孢子虫在罗平、元阳和普洱 3个县内查出 ,隐孢子则在泸水县、景洪市、普洱县、罗平县、元阳县和昆明西山区 6个县 (市 )内查出。 结论 圆孢子虫呈局部流行 ,隐孢子虫则流行分布广泛 ,学龄前儿童 2种孢子虫的感染率较高。

Abstract:  Objective To investigate the prevalence and distribution characteristics of Cyclospora cayetanensis and Cryptosporidium ssp. infection in diarrhea cases of Yunnan Province. Methods To collect fresh faeces from diarrhea cases in 7 counties/cities, examine the specimens by direct smear with iodine staining and modified acid-fast staining. Results The infection rate of C. cayetanensis and Cryptosporidium ssp. was 3.97% and 5.29%, respectively. The infection rate of the two pathogenic coccidians was as high as 10.64% and 8.51% in preschool children. C. cayetanensis was found in 3 counties and Cryptosporidium in 6 counties. Conclusion Both C. cayetanensis and Cryptosporidium ssp. are prevalent in Yunnan Province with the latter distributed more widely, and the two pathogens are more prevalent in preschool children.
