Identification of oral yeast species isolated from individuals with diabetes mellitus.
In our epidemiological study of 439 patients with diabetes mellitus, the proportion of Candida albicans isolated by the oral rinse technique was 67%. A comparison of the conventional germ tube test with the API 20C Auxanogram kit revealed that 23.6% (129/546) of germ tube-positive species were not identified as C. albicans by the kit. The API 20C Auxanogram therefore underestimated the prevalence of C. albicans. Additionally, a significant number of yeasts (138/1050, 13.1%) isolated from these patients could not be reliably identified by the kit.
