Isoenzyme analysis was performed on multiple strains of two commonly used reference cultures of Candida albicans (B311 and NCPF3153). Whereas strains originating from C. albicans B311 showed no variation in isoenzyme profiles, some strains derived from NCPF3153 were identical to B311 strains but others showed variation in their glucose-6-phosphate dehydrogenase isoenzymes. The results are compa...
