*The larger the genetic distance value, the greater the genetic difference between populations. PHOENIX represents primarily Coccidioides posadasii human clinical isolates from Yuma and Phoenix, Arizona. AZSOIL represents primarily environmental and veterinary clinical C. posadasii isolates from Arizona. TUCSON represents primarily human clinical C. posadasii isolates from Tucson, Arizona. SJV represents primarily C. immitis human clinical isolates from Bakersfield, California. SDMX represents primarily C. immitis human clinical isolates from San Diego, California, and Mexico. MEXICO represents primarily human clinical C. posadasii isolates from Mexico. TXSA represents primarily human clinical C. posadasii isolates from Texas, Brazil, Argentina, and Venezuela.
