Individuals infected with "B. dendrobatidis" are bathed in itraconazole solutions, and within a few weeks, previously infected individuals test negative for "B. dendrobatidis" using PCR assays. Heat therapy is also used to neutralize "B. dendrobatidis" in infected individuals. Temperature-controlled laboratory experiments are used to increase the temperature of an individual past the optimal temperature range of "B. dendrobatidis". Experiments, where the temperature is increased beyond the upper bound of the "B. dendrobatidis" optimal range of 25 to 30 °C, show its presence will dissipate within a few weeks and individuals infected return to normal. Formalin/malachite green has also been used to successfully treat individuals infected with chytridiomycosis. An Archey's frog was successfully cured of chytridiomycosis by applying chloramphenicol topically. However, the potential risks of using antifungal drugs on individuals are high.
