Cryptococcus gattii in the United States: Genotypic Diversity of Human and Veterinary Isolates

Abstract

We provide the most comprehensive report to date of genotypic diversity of US C. gattii isolates both inside and outside of the PNW. C. gattii may have multiple endemic regions in the US, including a previously-unrecognized endemic region in the southeast. Regional clusters exist both in California and the Southeastern US. VGII strains associated with the PNW outbreak do not appear to have spread substantially beyond the PNW.
