Cryptosporidium infection in HIV-seropositive and seronegative populations in southern Thailand.

Abstract

The prevalence of Cryptosporidium infection in 61 HIV-seropositive and 61 HIV-seronegative subjects (average age of 31 years for both groups) in Songkhla City, southern Thailand, was studied between October 1995 and June 1996. Most of the HIV-seropositive subjects (72%) were aged between 20 and 39 years. Cryptosporidium oocysts were detected in 6 (10%) HIV-seropositive and in 1 (2%) HIV-seronegative subjects. The number of Cryptosporidium oocysts observed in 20 microscopic fields ranged between one and >12 000. Among the 7 Cryptosporidium-positive subjects, 6 were adults (aged between 18 and 42 years) and one was a child aged 3 years. All of the Cryptosporidium infected subjects were male, and 2 were passing formed (normal) faeces. Biochemical findings revealed disorder of liver function in 5 of 6 Cryptosporidium infected HIV-seropositive subjects.
