BACKGROUND: In Mexico, Cryptococcus gattii sensu lato has been identified as the etiologic agent in approximately 10.8% of cryptococcosis cases; however, its isolation from natural sources, which would confirm its existence in the environment, has not been successful.
OBJECTIVE: To isolate C. gattii from environmental samples collected from trees within the movement area of a patient diagnosed with cryptococcosis caused by this species.
METHODS: Based on a database of clinical isolates characterized as C. gattii, a patient was contacted and his route of movement was obtained; through a geospatial analysis, nearby trees were located. Tree hollows were sampled and the Cryptococcus isolates obtained were biochemically and genetically typed.
RESULTS: Four Cryptococcus isolates were obtained from the trees Schinus molle, Erythrina coralloides and from a specimen of the genus Pinus: three of them were characterized as Cryptococcus neoformans sensu stricto and one as C. gattii sensu stricto.
CONCLUSIONS: Using a geographic information system led to delimit an environmental sampling area, resulting in the first documented report in Mexico of the isolation of C. gattii genotype VGI in nature.
