Abstract

To obtain a rapid genotyping method of Candida albicans, three polymorphic microsatellite markers were investigated by multiplex PCR. The three loci, called CDC3, EF3, and HIS3, were chosen because they are on different chromosomes so as to improve the chances of finding polymorphisms. One set of primers was designed for each locus, and one primer of each set was dye-labeled to read PCR signals by using an automatic sequencer. Amplifications were performed directly from the colonies harvested on the agar plate without a sophisticated DNA extraction step. At total of 27 reference strains and 73 clinical independent isolates were tested. The numbers of allelic associations were 10, 22, and 25 for the loci CDC3, EF3, and HIS3, respectively. The combined discriminatory power of the three microsatellites markers was 0.97. The markers were stable after 25 subcultures, and the amplifications were specific for C. albicans. An initial study of 17 clinical isolate pairs, including blood culture and peripheral sites, showed a similar genotype for 15 of them, confirming that candidemia usually originates from the colonizing isolate. Therefore, microsatellite marker analysis with multiplex PCR and automated procedures has a high throughput and should be suitable for large epidemiologic studies of C. albicans.
