Anatomical route of invasion and protective mucosal immunity in Trypanosoma cruzi conjunctival infection.

abstract：:In previous work (Jones, Infect, Immun. 30:78-89, 1980) a major cytoplasmic antigen of Candida albicans was identified. In both humans and experimental animals, this antigen is released from C. albicans during the course of an invasive C. albicans infection and elicits a specific antibody response. In this study, we u...
