Growth of fresh human isolates of some Candida species at 45 degrees C

A total of 452 fresh isolates of six Candida species from human sources were tested for their ability to grow on Sabouraud's glucose agar at 45 degrees C. The percentage of each species which grew at this temperature was: C. albicans (99%), C. tropicalis (90%), C. glabrata (93%), C. krusei (100%), C. parapsilosis (19%) and C. lusitaniae (80%). Some variation in the amount of growth obtained after 48 h incubation was also observed. Comparison of the results with data from the literature revealed a possibility of a difference in the ability to grow at 45 degrees C between fresh human isolates and laboratory stock strains of Candida species.
