Varietes and serotypes of Cryptococcus neoformans clinical isolates in Colombia.
The aim of this study was to contribute to the knowledge of the geographic distribution of Cryptococcus neoformans varieties, in Colombian patients, and to determine the mating types of such varieties. A total of 370 clinical isolates were studied. C. neoformans var. neoformans was identified in 95.2% of them. C. neoformans var. gattii in 4.8%, 4.5% being serotype B and 0.3%, serotype C. Fifty-...
متن کاملMolecular analysis of CAP59 gene sequences from five serotypes of Cryptococcus neoformans.
The nucleotide sequences of CAP59 genes from five serotypes of Cryptococcus neoformans were analyzed for their phylogenetic relationships. Approximately 600-bp genomic DNA fragments of the CAP59 gene were amplified from each isolate by PCR and sequenced. The CAP59 nucleotide sequences of C. neoformans showed more than 90% similarity among the five serotypes. By phylogenetic analysis, their sequ...
متن کاملGenetic relationship between Cryptococcus neoformans var. neoformans strains of serotypes A and D.
Cryptococcus neoformans serotypes A and D are responsible for the overwhelming majority of infections in patients with AIDS. The genetic relationship between the serotypes is poorly understood, but there are significant differences in the epidemiology and clinical presentation of serotype A and D infections. We evaluated the genetic relationship between reference C. neoformans strains belonging...
متن کاملMolecular Typing of IberoAmerican Cryptococcus neoformans Isolates
A network was established to acquire basic knowledge of Cryptococcus neoformans in IberoAmerican countries. To this effect, 340 clinical, veterinary, and environmental isolates from Argentina, Brazil, Chile, Colombia, Mexico, Peru, Venezuela, Guatemala, and Spain were typed by using M13 polymerase chain reaction-fingerprinting and orotidine monophosphate pyrophosphorylase (URA5) gene restrictio...
متن کاملAntifungal susceptibilities among different serotypes of Cryptococcus gattii and Cryptococcus neoformans.
We measured antifungal activity against 128 cryptococcal isolates (86 of C. neoformans and 42 of C. gattii) to determine if differences in serotype susceptibility exist. Contrary to previous results, we found no serotype susceptibility differences. Isavuconazole, posaconazole, and voriconazole demonstrated excellent potency against each isolate and serotype, including isolates with reduced fluc...
