Twenty-one chlamydospore-forming and germ tube-positive Candida albicans
clinical isolates from 15 human immunodeficiency virus (HIV)- positive and
3 HIV-negative patients were examined by two different genetic methods.
Multilocus enzyme electrophoresis and hybridization with the C.
albicans-specific Ca3 probe showed that such isolates can be split into two
genetically distinct groups that can be clearly distinguished. One group
mainly contained strains with atypical sugar assimilation patterns and
could be distinguished from the other group by the absence of intracellular
beta-glucosidase activity. All 13 strains belonging to this group were
isolated from the oral cavities of asymptomatic HIV-positive drug users and
may be less pathogenic than the eight strains from the other group isolated
either from HIV- positive patients with oropharyngeal candidiasis or from
HIV-negative patients with invasive candidiasis.
