Cryptococcus neoformans is an opportunistic fungal pathogen that causes meningitis in approximately 10% of patients with AIDS. New selectable markers which confer resistance to G418 or phleomycin when transformed into C. neoformans were made. A hygromycin-selectable marker was modified to allow selection with a single copy of the marker.

Cryptococcus neoformans is an opportunistic fungal pathogen that primarily affects immunocompromised individuals. Reverse genetics is commonly used to identify and characterize genes involved in a variety of cellular processes. In C. neoformans there is a limited set of positive selectable markers available to make gene deletions or other genetic manipulations. This has hampered the application of reverse genetics in this organism. We have adapted the Bacteriophage P1 Cre-loxP system for use in C. neoformans and successfully excised and reused the same drug marker, G418, to make two sequential gene deletions, lac1Delta and cap59Delta, in the same strain. This tool will allow investigators to make multiple sequential gene deletions in the same strain, which should facilitate the analysis of multigene families.
