Abstract Recent Cryptococcus gattii infections in humans and animals without travel history to Vancouver Island, as well environmental isolations of the organism other areas Pacific Northwest, led an investigation potential dispersal mechanisms. Longitudinal analysis C. presence trees soil showed patterns permanent, intermittent, transient colonization, reflecting population dynamics once pathogen is introduced a new site. Systematic sampling was associated with high-traffic locations. In addition, isolated from wheel wells vehicles on Island mainland footwear, consistent anthropogenic organism. Increased levels airborne were detected during forestry municipal activities such wood chipping, byproducts which are frequently used park landscaping. by these mechanisms may be useful model for emerging pathogens.
