Insights into the Cytoadherence Phenomenon of : The Putative Role of Phosphatidylserine.

is the most geographically widespread and the dominant human malaria parasite in most countries outside of sub-Saharan Africa and, although it was classically recognized to cause benign infection, severe cases and deaths caused by have remarkably been reported. In contrast to , which well-known ability to bind to endothelium and placental tissue and form rosettes is related to severity of the disease, it has been a dogma that is unable to undergo cytoadherent phenomena. However, some studies have demonstrated that red blood cells (RBCs) infected by can cytoadhere to host cells, while the molecules participating in this host-parasite interaction are still a matter of speculation.

Enteroparasitosis prevalence and parasitism influence in clinical outcomes of tuberculosis patients with or without HIV co-infection in a reference hospital in Rio de Janeiro (2000-2006).

Tuberculosis and intestinal parasites affect primarily low social and economic level populations, living clustered in precarious habitational settings. One of the interesting aspects of this interaction is the parasitism influence in cellular response to tuberculosis. In the present study, we evaluated the prevalence of enteroparasitosis in tuberculosis patients, HIV-infected and non HIV infected, and we observed the influence of helminth presence in the response to tuberculin skin test (TST) and tuberculosis clinical outcomes.
