ABSTRACT
The aim of this retrospective study was to analyze the relationship between occurrence of the serotypes of the Cryptococcus neoformans species complex in tree samples and the climatic conditions registered during samplings in four cities of Colombia, between 1992 and 2004, by means of a logistic regression model and lagged Pearson correlations. During 97 collection dates, 8220 samples from different tree species were taken, of which 2.63% were positive 56.5% yielded serotype B, 24.7% serotype C and 18.8% serotype A isolates. The prevalence of the serotypes varied among the cities. The results suggest that environmental climatic conditions, mainly humidity, temperature, evaporation and solar radiation, can affect the occurrence of the different serotypes in trees in a differential manner. These different climatic tolerances were reflected in the geographic distribution of the serotypes in Colombia. The climatic conditions for 15 days before the sampling date were correlated with positive or negative isolation of the different serotypes.
