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。
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.
