Timing the Origin of Cryptococcus gattii sensu stricto, Southeastern United States

Emerg Infect Dis. 2018 Nov;24(11):2095-2097. doi: 10.3201/eid2411.180975.

Abstract

We conducted molecular clock analysis of whole-genome sequences from a set of autochthonous isolates of Cryptococcus gattii sensu stricto from the southeastern United States. Our analysis indicates that C. gattii arrived in the southeastern United States approximately 9,000-19,000 years ago, long before its arrival in the Pacific Northwest.

Keywords: Bayesian analysis; Cryptococcus gattii; United States; emergence; fungi; southeastern United States; yeast.
