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

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.
