Enhancement of resistance and suppression of immunization against experimental Trypanosoma cruzi infection by Corynebacterium parvum. 1975

F Kierszenbaum

Intravenous but not intraperitoneal injection of killed Corynebacterium parvum either before or after intraperitoneal infection with the highly reticulotropic Tulahuén strain of Trypanosoma cruzi produced enhanced resistance against the infection in mice. In contrast, C. parvum had no effect when the infection was caused with the predominately myotropic Y strain of T. cruzi. C. parvum given intravenously before immunization with killed culture forms of the Y strain parasite consistently diminished the protective effect against subsequent infection, which could be obtained with antigen alone.

D014349 Trypanosoma cruzi The agent of South American trypanosomiasis or CHAGAS DISEASE. Its vertebrate hosts are man and various domestic and wild animals. Insects of several species are vectors. Trypanosoma cruzus,cruzi, Trypanosoma
D014355 Chagas Disease Infection with the protozoan parasite TRYPANOSOMA CRUZI, a form of TRYPANOSOMIASIS endemic in Central and South America. It is named after the Brazilian physician Carlos Chagas, who discovered the parasite. Infection by the parasite (positive serologic result only) is distinguished from the clinical manifestations that develop years later, such as destruction of PARASYMPATHETIC GANGLIA; CHAGAS CARDIOMYOPATHY; and dysfunction of the ESOPHAGUS or COLON.
