Batrachochytrium dendrobatidis infection in amphibians can be eliminated using a reduced concentration (0.0025%) and shorter duration (five minute baths for six days) of itraconazole than is generally used. Less mortality and fewer negative side effects were observed using this modified treatment protocol.

We quantify epidermal cell death in frogs with chytridiomycosis using two methods. First, we use terminal transferase-mediated dUTP nick end-labelling (TUNEL) in situ histology to determine differences between clinically infected and uninfected animals. Second, we conduct a time series analysis of apoptosis over infection using a caspase 3/7 protein analysis.
