Use temperature treatment to reduce chytridiomycosis infection

A replicated, controlled study in 2004 in a laboratory in the USA (Retallick & Miera 2007) found that heat treatment at 32°C cured western chorus frogs Pseudacris triseriata of chytridiomycosis. Three infected frogs died during treatment, but the remaining four tested negative for chytrid following treatment. All infected frogs kept at room temperature remained infected and four died. No uninfected frogs died with or without treatment. Weight gain in cured frogs was significantly greater than infected frogs (1.1–1.4 vs 0.7–0.9 g). Frogs were raised from eggs collected from the wild and were experimentally infected with chytrid. Seven infected and five uninfected frogs were placed in an incubator for five days at 32°C. Nine infected and 15 uninfected frogs were kept at room temperature (20°C). Frogs were weighed at days 172 and 257 and sampled for chytrid on day 172.
