Analysis and modeling of environmental prevalence in Minnesota using soil collected to compare basal and outbreak levels.

Outbreaks of blastomycosis, caused by the fungus , occur in endemic areas of the United States and Canada but the geographic range of blastomycosis is expanding. Previous studies inferred the location of through epidemiologic data associated with outbreaks because culture of from the environment is often unsuccessful. In this study, we used a culture-independent, PCR-based method to identify DNA in environmental samples using the BAD1 promoter region.
