Use temperature treatment to reduce chytridiomycosis infection Amphibian Conservation

A replicated, controlled study in a laboratory at the University of Zürich, Switzerland (Geiger et al. 2011) found that heat treatment over 26°C cured the majority of common midwife toad Alytes obstetricans tadpoles of chytridiomycosis. The percentage of tadpoles cured increased significantly with temperature (21°C: 20%; 26°C: 63%; 30°C: 88%). Tadpoles were wild caught and were tested for chytridiomycosis before and 6–10 days after treatments. Ten infected tadpoles were randomly assigned to each treatment: water temperature at 21°C or 26°C for five days, or water at room temperature and 30°C for 59 hours. After the experiment, toads were treated using itraconazole fungicide and released at the capture site.
