RESUMO
The susceptibility of yeasts to six chemicals at appropriate concentration by disk diffusion test was done on 50 strains of yeasts isolated from different sources. It was able to identify 58% of the strains as C. albicans, 12% C. tropicalis, 10% C. pseudotropicalis, 3% T. Glabrata, 6% C. Stellatoidea, 4% S. Cerevisiae and 2% c. guilliermondii. The disk diffusion test was compared with the conventional methods of identification and API 20c system and the results showed that this test correctly identified 38/50 [76%] and 22/25 [88%] respectively. In conclusion, this test is highly significant in identification of most yeast species studied as well as it is simple inexpensive and technically straight-forward and for most isolates gave an identification after 24 hours
