摘要
Adhesion of Candida albicans and Streptococcus mutans was studied by incubation of radiolabelled cells with acrylic test specimens in a chemically defined growth medium. Strep. mutans adhered firmly in the presence of sucrose, while C. albicans was only loosely attached to the acrylic in both glucose and sucrose media. Firm adhesion of C. albicans occurred when the yeast was incubated simultaneously with Strep. mutans, in the presence of sucrose. The adhesion of C. albicans was also stimulated by incubation with Strep. mutans culture supernatants. Adhesion was not affected by the presence of partially purified glucosyltransferase from Strep. mutans IB. Coaggregation between C. albicans and Strep. mutans upon growth in sucrose medium was observed by light and scanning electron microscopy. No coaggregation was observed in the presence of glucose.
