Molecular Evidence of Autochthonous Environmental Acquisition of Fonsecaea Pediatric Infection in the United States.

Fonsecaea species cause chromoblastomycosis and phaeohyphomycosis, but links between environmental exposure and infection are poorly defined. We describe a 4-year-old boy with finger swelling after oak tree laceration in Houston, Texas. Broad-range polymerase chain reaction identified F. pedrosoi or F. monophora, and metagenomic sequencing of tree bark and soil detected Fonsecaea DNA.
