Internal transcribed spacer sequencing versus biochemical profiling for identification of medically important yeasts.
In this study, we established an in-house database of yeast internal transcribed spacer (ITS) sequences. This database includes medically important as well as colonizing yeasts that frequently occur in the diagnostic laboratory. In a prospective study, we compared molecular identification with phenotypic identification by using the ID32C system (bioMérieux) for yeast strains that could not be i...
متن کاملPolymorphic internal transcribed spacer region 1 DNA sequences identify medically important yeasts.
Species-specific polymorphisms in the noncoding internal transcribed spacer 2 (ITS2) region of the rRNA operon provide accurate identification of clinically significant yeasts. In this study, we tested the hypothesis that ITS1 noncoding regions contain diagnostically useful alleles. The length of ITS1 region PCR products amplified from 40 species (106 clinical strains, 5 reference strains, and ...
متن کاملBiochemical identification of clinically important yeasts.
Four commercially available kits for the speciation of yeasts were tested against 50 clinical isolates that had been identified by conventional methods. On biochemical grounds alone, the four systems varied from 71% to 100% in their efficiency in identifying Candida albicans. Yeasts other than C. albicans were identified with an efficiency varying from 24% to 83%. Conclusions are drawn on the v...
متن کاملGenome mapping of medically important yeasts
1 Physical and genetic maps are important steps in the process of yeast genome exploration. One of the first strategies of physical mapping comprised a combination of whole genome shotgun and restriction analysis of large fragments cloned in BAC/YAC libraries. During last years, new approaches have emerged, such as screening of BAC libraries using PCR assays, BAC pooling strategies or in silico...
متن کاملActivity of phenothiazines against medically important yeasts.
Two phenothiazine compounds, trifluoperazine and chlorpromazine, inhibited growth in vitro of the five most common pathogenic yeasts, with MICs ranging from 10 to 40 micrograms/ml. Daily intraperitoneal injections of trifluoperazine (4 to 7 mg/kg of body weight) increased the survival of mice experimentally infected with Candida albicans or Cryptococcus neoformans. The potential use of these dr...
