Abstract

A novel approach for the assessment of adherence of Candida albicans to translucent acrylic material is described. The method uses the inverted microscope to visualise yeast adhering to acrylic surfaces while the test material remains immersed in buffer. Adherent cells were not subjected to surface tension forces that can occur during drying processes, so that an even distribution of yeast with no aggregation occurred. The process of counting attached yeast was subsequently performed without difficulty. From the 11 C albicans isolates examined, two groups were evident with respect to acrylic adherence: one group of four isolates with an adherence level of 400 yeast/mm2 acrylic, and one group of seven isolates with adherence levels of 1000 yeast/mm2 acrylic.
