Specific cellular and humoral immune response in Balbc mice immunised with an expression genomic library of Trypanosoma cruzi

An expression genomic library of Trypanosoma cruzi (T. cruzi) constructed using pcDNA3 plasmid was used for the immunisation (25 ug) of Balblc mice. Expression of T. cruzi antigens in the muscle of inoculated mice was detected by indirect immunofluorescence 7 days after immunisation. Specific IgG antibodies were significatively increased (P ~0.05) in animals that were reimmunised with 50 ,ug of the genomic library. An antigen specific lymphoproliferative response was detected in one animal of 0 1998 Elsevier Science Ltd. All the group inoculated with one dose of the library rights reserved
