Trypanosoma cruzi (Kinetoplastida Trypanosomatidae): ecology of the transmission cycle in the wild environment of the Andean valley of Cochabamba, Bolivia.

abstract：:Murine malarial parasites have long been characterized by their requirement for either antibody-mediated immunity (AMI) or cell-mediated immunity (CMI) for suppression of acute parasitemia, with Plasmodium yoelii reportedly requiring AMI for suppression and P. chabaudi requiring CMI. To assess this characterization in...
