Mycology Practice Exam

Aspergillus species are common environmental molds that thrive in soil, compost, and decaying vegetation. Their spores are readily released into the air from these materials, making inhalation the usual route of exposure. This ecological niche is why soil and decaying vegetation are the most consistently associated environmental exposures. Freshwater lakes or oceans aren’t typical reservoirs for these fungi in the context of inhalational exposure, and human skin isn’t an environmental exposure route for acquiring aspergillosis. So, exposure to soil and decaying vegetation best captures where Aspergillus is commonly encountered.
