Abstract:
Based on epidemiologic data during a blastomycosis outbreak, exposure within the home was suspected for two case patients that resided together. Soil and air samples were collected from the basement of their residence. Samples were tested for Blastomyces by culture and polymerase chain reaction (PCR) to compare with an available clinical isolate. An air sample from the basement of the residence was PCR positive for Blastomyces. Sequence data from the air sample and the outbreak clinical isolate were identified as different Blastomyces spp. Despite this, our findings suggest that the basement was suitable for the growth of Blastomyces and airborne organism was circulating.
