[Prevalence survey on Cyclospora cayetanensis and Cryptosporidium ssp. in diarrhea cases in Yunnan Province].
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.

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.
