The protective effect of antibody in immunity to murine chlamydial genital tract reinfection is independent of immunoglobulin A.
The resolution of primary and secondary chlamydial genital infection in immunoglobulin A (IgA)-deficient (IgA(-/-)) mice was not different from that in IgA(+/+) mice. Furthermore, depletion of either CD4(+) or CD8(+) T cells prior to reinfection of IgA(+/+) or (-/-) mice had limited impact on immunity to reinfection. Thus, although antibody contributes importantly to immunity to chlamydial genital tract reinfection, IgA antibodies are not an absolute requirement of that protective response.
