Balrachochytrium dendrobatidis is a pathogen of amphibians that has caused severe population declines on several continents, and little is known about the conditions that favor epidemics. The zoospore activity, temperature, and pH requirements of B. dendrobutidis were investigated to help understand the ecology and transmission of this pathogen. Over 95% of the chytrid's zoospores stop moving in less than 24 hours, and the zoospores swam less than 2 cm before encysting on tryptone agar. B. dendrobutidis zoospores were not attracted to tryptone, gelatin hydrolysate, casamino acids, keratin, gelatin, glucose, or lactose. The chytrid grew and reproduced at temperatures ranging from …
