The polymorphism of a TTC/TTTC microsatellite in the promoter sequence of
the elongation factor 3 gene of Candida albicans was investigated by PCR.
One primer was fluorescein labeled, and PCR signals were read with an
automatic sequencer. Twenty-nine reference strains and 31 independent
clinical isolates were studied. Eleven different alleles were identified,
giving 16 different profiles among the 60 strains tested, with a
discriminatory power of 0.88. This marker is stable upon subculture, and
reproducibility was achieved by automated procedures. When several
microsatellite markers are available, many isolates can be rapidly and
reproducibly tested for epidemiological questions, such as the prevalence
of a given strain in a hospital setting and transmission between patients.
