Experimental infection of almond trees seedlings (Terminalia catappa) with an environmental isolate of Cryptococcus neoformans var. gattii, serotype C.
Recently, our laboratory reported the isolation of Cryptococcus neoformans var. gattii, serotype C for the first time from almond trees (Terminalia catappa) detritus. The aim of the present study was to establish the survival of C. neoformans in almond trees seedlings. Thirty seedlings were infected in the stems and samples were taken and processed at different times and by different techniques. No morphological alterations (macro or microscopic) were observed in the infected plants. However, C. neoformans was found to be viable for at least 100 days after infection. These data constitute our first approach towards the understanding of the yeast interactions with a host-plant.
