Wisconsin scientists discover a master key to microbes' pathogenic lifestyles

MADISON - For some microbes, the transformation from a benign lifestyle in the soil to that of a potentially deadly human pathogen is just a breath away. ... Inhaled into the lungs of a mammal, spores from a class of six related soil molds found around the world encounter a new, warmer environment. And as soon as they do, they rapidly shift gears and assume the guise of pathogenic yeast, causing...
