| Abstract | |
This study was aimed to: identify the 70 isolates of Candida in a culture collection by the traditional method and by API 20C; identify the presence of C. dubliniensis; determine and compare the minimum inhibitory concentrations (MICs) of these samples in regard to the seven drugs (E-test); molecularly characterize sequential samples from the same patient by the PFGE technique; study the genotypic profile of all the isolates of C. albicans and C. parapsilosis by means of the microsatellite technique and compare the results with those obtained by the PFGE technique. The level of agreement between the traditional method and the API 20C was 93%. No isolate of C. dubliniensis was identified in the study. In relation to antifungal susceptibility, most of the samples presented a high percentage of susceptibility to the seven drugs tested. The molecular analysis by the PFGE technique revealed six different karyotype profiles among 24 sequential samples. In the comparison between the PFGE and microsatellite, the latter showed a greater discriminatory power for samples. (AU) | |
