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-five of the 74 (74%) isolates studied were mating type "alpha", all of them C. neoformans var. neoformans. Serotype C had been previously reported only once in South American countries.
