The purpose of this study was to determine whether HIV-1 infected patients in our community were more susceptible to and infection than non-HIV-infected individuals. The prevalence and frequency of invasive amebiasis was determined in 203 HIV/AIDS subjects and 140 close relatives or sexual partners, all of whom were HIV. Anti– antibodies (IgG, IgA) were assessed as indicators of invasive infection. Polymerase chain reaction (PCR) was used for the characterization of the species. The prevalence estimated with PCR data showed that infection was more common in the HIV/AIDS group (25.32%), than in HIV contacts (18.46%). + infection was more frequent in HIV/AIDS patients (13.3%), than in HIV contacts (0.7%). and/or infection was highly prevalent in HIV/AIDS patients (34.1%) without evidence of recent or current invasive disease. Contacts of HIV/AIDS patients who were infected with were asymptomatic cyst passers. Our results suggest that strains prevalent in the studied community appear to be of low pathogenic potential.
