Genetic Diversity of the Internal Transcribed Spacers (ITS) and 5.8S rRNA Genes among the Clinical Isolates of Candida parapsilosis in Brazil and Japan
2005
: The internal transcribed spacer (ITS) region including 5.8S rDNA sequences of 58 isolates of Candida parapsilosis in Brazil and Japan was analyzed. Although most of the C. parapsilosis strains tested were confirmed to belong to three already reported genetically distinct groups (I, II and III) based on their ITS region sequences, 5 strains of the Brazilian isolates showed different sequences from those heretofore reported and suggested a presence of new genotype. For these strains of C. parapsilosis, we proposed a new genetic group (IV). The sequence similarities of this new group of IV to I, II and III were 87.4%, 94.7% and 87.3% in the ITS1 region, respectively. Genetic diversity in ITS regions of the remaining C. parapsilosis strains in Brazil and Japan was also discussed.
