[Cryptosporidium species in persons with HIV infection].

Oocysts of Cryptosporidium sp. were detected in the faeces of 65 subjects with the HIV virus, using the concentrating flotation method in a sugar solution and differential staining with methyl violet. In positive cases (a total of 16 subjects) continuous as well as intermittent excretion of oocysts in faeces was recorded, the longest excretion period being up to 15 months. The presented findings of oocysts confirm that Cryptosporidium sp. is a common intestinal pathogenic organism in the investigated group of subjects, and with regard to its pathogenity and opportunistic character they must be subjected to regular parasitological examinations.
