Abstract

A large outbreak of chytridiomycosis occurred in captive metamorphs of Mixophyes fasciolatus that died between 9 and 25 days post metamorphosis. The mortality rate in infected tubs was 100% and more than 500 frogs died. Examination of the husbandry records suggested that tadpoles had been infected before two weeks of age. However, a sample of tadpoles separated before hatching remained uninfected. We studied the changes in distribution of keratin and sporangia of Batrachochytrium dendrobatidis in tadpoles during development, by examination of histology sections stained with Ayoub-Shklar stain. Keratin occurred only on the mouthparts during most of tadpole life, and appeared onthe feet shortl..
