A Phylogeographic Description of in the United States.

Histoplasmosis is one of the most under-diagnosed and under-reported endemic mycoses in the United States. is the causative agent of this disease. To date, molecular epidemiologic studies detailing the phylogeographic structure of in the United States have been limited. We conducted genomic sequencing using isolates from histoplasmosis cases reported in the United States. We identified North American Clade 2 (NAm2) as the most prevalent clade in the country. Despite high intra-clade diversity, isolates from Minnesota and Michigan cases were predominately clustered by state. Future work incorporating environmental sampling and veterinary surveillance may further elucidate the molecular epidemiology of in the United States and how genomic sequencing can be applied to the surveillance and outbreak investigation of histoplasmosis.
