Fertile Cryptococcus Neoformans VAR. Neoformans (C. Deneoformans) Isolates from Natural Environment in Kosovo.

A total of 300 tree-associated samples were collected from green areas in three towns in Kosovo, and cultured to isolate Cryptococcus species. One soil sample from Prizren tested positive, yielding three isolates identified as C. neoformans var. neoformans (C. deneoformans), molecular type VNIV, two MATα and one MATa. Mating experiments revealed that they were fertile when crossed together, and MLST analysis showed unique sequence types not found in the global database. The study reports the presence of C. neoformans strains in the environment in Kosovo and highlights the importance of monitoring pathogen distribution and potential impacts of climate change.
