retreat sites of rain forest stream frogs are not a reservoir for batrachochytrium dendrobatidis in northern queensland, australia.chytridiomycosis is a potentially fatal disease of amphibians caused by batrachochytrium dendrobatidis, and is implicated in declines and extinctions of amphibian populations and species around the world. to cause local host extinction, a disease organism must persist at low host densities. one mechanism that could facilitate this is the ability to persist in the environment. in the laboratory, b. dendrobatidis spreads by both frog-to-frog and environment-to-frog transmission, and can persist on ...200717425258
latitudinal variation in the prevalence and intensity of chytrid (batrachochytrium dendrobatidis) infection in eastern australia.chytridiomycosis is a recently emerged, infectious skin disease of amphibians that has been linked directly to mass mortalities, population declines, and species extinctions worldwide. an understanding of the factors that limit the distribution and abundance of batrachochytrium dendrobatidis (the etiological agent of chytridiomycosis) is urgently required. we conducted disease surveys at 31 lowland sites distributed north-south along 2315 km of the australian east coast that encompassed 20.8 deg ...200717883493
urinary corticosterone metabolites and chytridiomycosis disease prevalence in a free-living population of male stony creek frogs (litoria wilcoxii).the emerging amphibian disease chytridiomycosis, which is caused by the fungal pathogen (batrachochytrium dendrobatidis, bd), has caused mass mortalities of native amphibian populations globally. there have been no previous studies on the relationships between stress hormones in free-living amphibians and bd infections. in this study, we measured urinary corticosterone metabolite concentrations and bd infections within free-living populations of male stony creek frog (litoria wilcoxii) in queens ...201222387450
