Serum antibody response of gnotobiotic athymic and euthymic mice following alimentary tract colonization and infection with Candida albicans.
Colonization and infection evoked specific immunoglobulin responses to Candida albicans antigens in gnotobiotic nu/+ mice which appeared to correlate with clearance of infected mucosal surfaces (tongue and stomach). Conversely, colonized and infected nu/nu mice formed some IgM but no detectable IgG or IgA antibodies against C. albicans antigens. Although chronic mucosal infections of tongue and stomach persisted in nu/nu mice, they were able to resist overwhelming mucosal and systemic infections with C. albicans. Thus, C. albicans specific antibodies may play a role in clearance of mucosal candidiasis (tongue and stomach), but these antibodies do not appear to be necessary for protecting athymic mice against systemic candidiasis of endogenous origin.
