Experimental studies on Trypanosoma (Schizotrypanum) cruzi strains isolated from man, from animals and from triatomine bugs in Brazil

A study on nine strains of T. cruzi isolated from man, from animais and from triatomine bugs in Brazil are described. The parasites were slightly viscerotropic in white mice in six of the strains, highly viscerotropic and cardiotropic in two strains, and asymptomatic on one strain. Mechanical and cy...

Description
Summary:A study on nine strains of T. cruzi isolated from man, from animais and from triatomine bugs in Brazil are described. The parasites were slightly viscerotropic in white mice in six of the strains, highly viscerotropic and cardiotropic in two strains, and asymptomatic on one strain. Mechanical and cyclical passage from infected to healthy mice, and treatment of the infected mice with immunosuppressant drug, did not increase the blood parasitaemia or strain virulence. The results of biometric studies on the blood trypanosomes from each strain are also described. The various aspects on the importance of T. cruzi strain Identification are emphasized and discussed.
