Evidence for Trypanosoma cruzi in adipose tissue in human chronic Chagas disease

Microbes Infect. 2011 Nov;13(12-13):1002-5. doi: 10.1016/j.micinf.2011.06.002. Epub 2011 Jun 21.

Abstract

Trypanosoma cruzi the cause of Chagas disease persists in tissues of infected experimental animals and humans. Here we demonstrate the persistence of the parasite in adipose tissue from of three of 10 elderly seropositive patients with chronic chagasic heart disease. Nine control patients had no parasites in the fat. We also demonstrate that T. cruzi parasitizes primary adipocytes in vitro. Thus, in humans as in mice the parasite may persist in adipose tissue for decades and become a reservoir of infection.
