October 31 is Halloween and Dr. Jim Wellehan is embracing spooky season for Animal Airwaves Live. An expert on the evolution and ecology of nondomestic animal pathogens, with an emphasis on molecular diagnostics and pathogen discovery, Wellehan will talk about bat pathogens, the evolution of infectious diseases and the overall clinical impacts of those diseases on wildlife animals, populations and ecosystems. Despite the bad rap that bats get for their association with disease outbreaks, he’ll explain the important role bats play in supporting agriculture, their history of co-existing with viruses and how flight patterns and adapting to new pathogens have been factors in their evolution.
