Effects of systemic cell-mediated immunity on vaginal candidiasis in mice resistant and susceptible to Candida albicans infections.

Studies to date with CBA/J mice suggest a limited role for systemic cell-mediated immunity (CMI) against vaginal Candida albicans infections. The results of the present study show that preinduced Candida-specific systemic CMI was equally nonprotective against C. albicans vaginal infections in mice with high (BALB/cJ), low (DBA/2), or intermediate (CBA/J) resistance to C. albicans infections. Similarly, the locally acquired partial protection against a second C. albicans vaginal infection was equally observed with BALB/cJ, DBA/2, and CBA/J mice. These results indicate that observations made previously with CBA/J mice were not murine strain specific and provide additional support for the hypothesis that systemic CMI does not represent a dominant host defense mechanism at the vaginal mucosa.
