Introduction: Human co-infection with Plasmodium falciparum and helminthes is ubiquitous throughout Africa. This study aimed to determine the co-infections of Plasmodium falciparum infection in HIV and intestinal parasitic infections, and their immunological distribution, in Benin City, Nigeria.

Methodology: A total of 2,000 stool specimens from HIV-positive patients and 500 controls (HIV-negative individuals) were examined for ova, cysts, or parasites using standard procedures.

Background: The role of opportunistic infections in accelerating disease progression in HIV-positive individuals, leading to quick death, is still receiving serious attention. The objective of this study was to determine the prevalence of Isospora belli infections in HIV-positive patients in Edo State, Nigeria between August 2007 and March 2008.

Methods: A total of 268 samples from HIV-positive patients and 20 samples from HIV-negative patients were processed using the modified Ziehl-Neelsen staining technique to microscopically identify the presence of I.
