摘要: The genetic diversity of recent clinical isolates Candida albicans in Japan was studied on the basis amplified DNA band lengths determined with a specific PCR primer reported to have been designed span transposable intron region 25S rRNA gene. Our analyses 301 C. showed that they could be classified into five genotypes: genotype A (172 isolates), B (66 C (56 D (C. dubliniensis; 5 and new (designated E; 2 isolates). E characterized group I intron-like sequence, which is longer than hitherto ones has nucleotide sequence length 962 bp. analysis 962-bp indicated it composed an similar dubliniensis 621 bp 341-bp insertion. Analysis internal transcribed spacer (ITS) strain its identical those strains other genotypes, only few base substitution differences. Throughout study, possible horizontal transfer between suggested. high degree correlation presence susceptibility antifungal agent flucytosine observed. examined present study when were compared by randomly polymorphic fingerprinting pattern analysis, this also confirmed ITS sequences.
