Journal ArticleDOI

Pathogenesis of chytridiomycosis, a cause of catastrophic amphibian declines.

TL;DR: It is shown that Bd infection is associated with pathophysiological changes that lead to mortality in green tree frogs (Litoria caerulea), and in diseased individuals, electrolyte transport across the epidermis was inhibited by >50, plasma sodium and potassium concentrations were respectively reduced by ~20% and ~50%, and asystolic cardiac arrest resulted in death.
Journal ArticleDOI

Recent Asian origin of chytrid fungi causing global amphibian declines

Simon J. O’Hanlon, +65 more
- 11 May 2018 - 
TL;DR: This article used whole-genome sequencing to solve the spatiotemporal origins of the most devastating panzootic to date, caused by the fungus Batrachochytrium dendrobatidis, a proximate driver of global amphibian declines.
Journal ArticleDOI

Electrolyte depletion and osmotic imbalance in amphibians with chytridiomycosis.

TL;DR: It is suggested that B. dendrobatidis kills amphibians by disrupting normal epidermal functioning, leading to osmotic imbalance through loss of electrolytes, which is fundamental to understanding the host-pathogen relationship and thus the population declines attributed to B. Dendrobatides.
Journal ArticleDOI

Additional disinfectants effective against the amphibian chytrid fungus Batrachochytrium dendrobatidis

TL;DR: TriGene is the most effective disinfectant yet to be found, and both TriGene and F10 are more effective than various disinfectants tested in previous studies.
Journal ArticleDOI

High adult mortality in disease-challenged frog populations increases vulnerability to drought.

TL;DR: It is found that Bd-infected populations have a severely truncated age structure associated with very high rates of annual adult mortality, and truncation of age structure erodes the capacity of populations to withstand periodic recruitment failure; a common challenge for species reproducing in uncertain environments.
