The chytrid fungus Batrachochytrium dendrobatidis (Bd) has had devastating impact on amphibian populations in many parts of the world and its impact continues, threatening efforts at captive breeding and reintroduction of species. A new paper reports that frogs studied can acquire resistance, behavioral, immunological or both. In experiments, McMahon et al. (2014, Nature) show that frogs exposed and infected by Bd, but subjected to temperature clearance, learn to avoid sources of infection. With forced exposure, the number of previous exposures was a negative predictor of reinfection and a positive predictor of lymphocyte proliferation, thus overcoming pathogen-induced immunosuppression. These results suggest several therapeutic approaches to dealing with Bd.
