    Background: Microsporidiasis, which is of great concern for immunocompromised patients, is poorly studied in developing countries. Objectives: A study was carried out amongst HIV-positive hospital patients and HIV- negative hospital controls in Ilorin, Nigeria, between January 2009 and July 2010 to determine the prevalence and intensity of Microsporidium spores and the complications associated with their presence. Method: Stool samples from 750 HIV-positive patients and 375 HIV-negative patients were studied using the Chromotrope-2R staining technique. Determination of CD4+ count was performed on the Partec Cyflow SL-3 CD4/8 instrument. Intensity of spores was determined by counting the total number of the spores in a 10 μl stained smear of stool. Images were captured with Phenix Microimage Analysis Software and data obtained were analysed using the Statistical Package for the Social Sciences. Results: The prevalence of Microsporidium isolates amongst the HIV-positive hospital patients was significantly higher (42.4%) than amongst the HIV-negative controls (19.2%) (p < 0.05). The intensity of microsporidial spores amongst HIV-positive hospital patients was also significantly higher than amongst the controls (p < 0.05). However, the difference in the intensity of spores amongst HIV-positive patients who were on antiretroviral therapy (n = 411) and those who were not (n = 339) was not significant (p = 0.236). Microsporidiasis in HIV infection infection was common amongst patients with with low CD4+ counts, diarrhoea, body rashes and cough. Conclusion: Both the prevalence and intensity of Microsporidiasis are high amongst HIV- positive hospital patients; campaigns to promote awareness, prevention and control are required. Laboratory testing for microsporidia in HIV patients should be performed routinely so as to identify the organism for prompt medical attention.
