Growth of fresh human isolates of someCandidaspecies at 45°C

Abstract

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°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°C between fresh human isolates and laboratory stock strains of Candida species.
