USF study: Amphibians can acquire resistance to deadly fungus
Date:7/9/2014

Tampa, Fla. (July 9, 2014) Emerging fungal pathogens pose a greater threat to biodiversity than any other parasitic group, causing population declines of amphibians, bats, corals, bees and snakes. New research from the University of South Florida published in the prestigious journal Nature reveals that amphibians can acquire behavioral or immunological resistance to a deadly chytrid fungus implicated in global amphibian population declines.

"Acquired resistance is important because it is the basis of vaccination campaigns based on 'herd immunity', where immunization of a subset of individuals protects all from a pathogen," said Jason Rohr, an associate professor of integrative biology who led the research team with Taegan McMahon, a USF alumnus who is now an assistant professor of biology at the University of Tampa.

One experiment in the study revealed that after just one exposure to the chytrid fungus, frogs learned to avoid the deadly pathogen.

In subsequent experiments in which frogs could not avoid the fungus, frog immune responses improved with each fungal exposure and infection clearance, significantly reducing fungal growth and increasing the likelihood that the frogs survived subsequent chytrid infections.

"The amphibian chytrid fungus suppresses immune responses of amphibian hosts, so many researchers doubted that amphibians could acquire effective immunity against this pathogen," Rohr said. "However, our results suggest that amphibians can acquire immunological resistance that overcomes chytrid-induced immunosuppression and increases their survival."

Rohr also noted that "variation in the degree of acquired resistance might partly explain why fungal pathogens cause extinctions of some animal populations but not others."

"The discovery of immunological resistance to this pathogenic fungus is an exciting fundamental breakthrough that offers hope, and a critical tool for dealing with th
