Abstract

Three-month-old male Crl:CD1(ICR)BR and C3H/HeJ mice were fed chow containing Candida albicans for 14 days, while similar control mice were fed regular food. Stool cultures were done for all mice before and after administration of the special diet. Stool cultures were repeated 48 h, 1 week, and 1 and 3 months after stopping the diet for Crl:CD1(ICR)BR mice and again 5 months afterward for C3H/HeJ mice. Some animals were sacrificed at the end of the special diet, and cultures and histopathologic examination of various organs were performed. Colonization with C. albicans occurred in the Candida-fed mice, and the fungus was maintained in the gastrointestinal tract at a concentration of 10(3) to 10(4) CFU/g of stool for up to 5 months. There was no histologic evidence of organ infection with Candida spp. The fungus was not found in stool cultures or organs of mice in the control group. The results suggest that persistent gastrointestinal colonization of adult mice by C. albicans can be achieved without immunosuppression. Thus, with additional manipulations, this model could be useful for studying the role of gastrointestinal colonization by C. albicans in the development of systemic infection.
