Relative effectiveness of various yeasts, Candida spp. and Torulopsis glabrata, for inducing palatal infection in the Wistar rat.

Candida albicans serotypes A and B, Candida tropicalis and Torulopsis glabrata were tested for their ability to produce palatal candidosis in the rat. C. albicans serotype A consistently produced palatal candidosis whereas serotype B did so in only two of five animals tested, indicating a difference in pathogenicity of the two serotypes. C. tropicalis and T. glabrata did not induce changes under the conditions tested and their colonization of palatal mucosa in commensal form was dependent on the presence of an acrylic plate.
