Sterol content and polyene antibiotic resistance in isolates of Candida krusei, Candida parakrusei, and Candida tropicalis

Abstract
Three isolates, 1 from each species of C. krusei, C. parakrusei and C. tropicalis, obtained from infected patients, were more tolerant of significantly higher concentrations of polyene antibiotics than the corresponding reference wild types. the resistant strains isolated had the same sterols as their wild-type counterparts but in lower concentrations.
