Isospora belli infection in children, a third occurrence in Thailand.

Two cases of Isospora belli infection were found in stool examinations of 222 children of the gpvernment orphanage in Pagkred District, Nonthaburi Province. The authors collected 222 faecal specimens in September 1985 to study about the intestional parasitic infection in these children. The stool specimens were examined by fresh simple saline smear technique and were confirmed by iodine preparation. The rate of overall intestinal parasitic infection (both helminthes and protozoa) was 53.15% and the rate of Isospora belli infection was 0.9%. This is the third occurrence of human isosporiasis belli in Thailand.
