Abstract
Determination of ploidy was performed on isolates of Candida albicans from clinical sources by measuring nuclear DNA content with fluorescent microscope photometry. By this criterion and UV irradiation survival experiments, haploid, diploid, and tetraploid strains were identified in this organism. The dimensions of nucleus-associated organelles (equivalent to spindle pole bodies) in these strains increased as a function of ploidy number.
