protozoan infections and hiv-1 infection: a review.reactivation of latent infection is the principal mechanism relating toxoplasma gondii and pneumocystis carinii to hiv. less common is reactivation in leishmania donovani, trypanosoma cruzi, and microsporidian infections. an impaired primary immune response occurs in all these infections, and also with cryptosporidium and isospora belli. association of hiv infection with gut parasites including giardia lamblia and entamoeba histolytica, and also with trichomonas vaginalis infection is likely to ...19921396192
[aids and gastrointestinal tract: a summary for gastroenterologists and surgeons].the majority of patients with aids suffer from diarrhea and weight loss, as well as opportunistic infection and tumors of the gastrointestinal tract; endoscopy is frequently necessary. often, but not always, it is possible to identify an opportunistic tumor or infection which explains the patient's signs and symptoms. in other cases, hiv may itself be pathogenic. the most important opportunistic pathogens are candida albicans (stomatitis and esophagitis), cytomegalovirus and herpes simplex virus ...19902159657
parasitic diseases. diseases associated with acquired immunodeficiency syndrome.there are several protozoan infections that cause relatively benign illness in normal individuals but result in severe disease manifestations in patients with aids. these diseases include pneumocystis carinii pneumonia, cns toxoplasmosis, cryptosporidiosis, and isosporiasis. pneumocystis carinii pneumonia (pcp) caused by pneumocystis carinii, is the most common opportunistic infection in aids. it is seen in more than 80% of individuals with this syndrome. although historically classified as a pr ...19912011633
