Induction of immune and adjuvant immunoglobulin G responses in mice by Brucella lipopolysaccharide.

abstract：:The immunopathology of Chagas' disease was studied in the experimental model of chronic infection in C57BL/10JT or mice. Sublethal infection with Trypanosoma cruzi, Y strain, induced specific antibodies and a delayed hypersensitivity response to parasite antigens. Mice developed chronic chagasic myocarditis but not sk...
