Concurrent Cryptosporidium and Cystoisospora infection in a patient with HIV infection.

Patients having human immunodeficiency virus infection or acquired immunodeficiency syndrome (HIV/AIDS) are prone to suffer from diarrhea due to parasitic infestations which are more common in developing countries. Cryptosporidium, Cystoisospora, and Microsporidia species are among the important diarrhea causing protozoan parasites responsible for significant morbidity and mortality in HIV-infected patients. Although HIV-2 infection is uncommon in India, it is reported infrequently from the various regions of India. Although infections due to these protozoan parasites are common in HIV/AIDS patients, mixed infection is rarely reported. Here, we report the case of concurrent Cryptosporidium and Cystoisospora infection with probable HIV-1 and HIV-2 co-infection.
