It is important for the scientific community and conservation agencies to recognize and manage the threat of chytridiomycosis to remaining species of frogs, especially those that are naive to the pathogen.
Pathogenesis of Chytridiomycosis, a Cause of Catastrophic Amphibian Declines
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.

Chytridiomycosis is a major cause of mortality in free-living and captive amphibians in Australia and mortality rate increases at lower temperatures.

A global, quantitative assessment of the amphibian chytridiomycosis panzootic demonstrates its role in the decline of at least 501 amphibian species over the past half-century and represents the greatest recorded loss of biodiversity attributable to a disease.

Focusing on Hendra virus, but also addressing Nipah virus, Ebola virus, Marburg virus and coronaviruses, this work delineates this cross-species spillover dynamic from the within-host processes that drive virus excretion to land-use changes that increase interaction among species.

The results indicate that amphibian populations can face significant ongoing pressure from chytridiomycosis long after epidemics associated with initial Bd invasions subside, an important consideration for the long-term conservation of many amphibian species worldwide.

Although mortality in 3 groups of 15 green tree frogs Litoria caerulea exposed to 3 isolates of Batrachochytrium dendrobatidis was 100%, time to death varied with isolate, highlighting the importance…
Electrolyte depletion and osmotic imbalance in amphibians with chytridiomycosis.

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.
Distribution of Batrachochytrium dendrobatidis and pathology in the skin of green tree frogs Litoria caerulea with severe chytridiomycosis.

The number of sporangia was highly variable and this appeared to be related to the stage in the cycle of sloughing, and other pathological changes such as hyperkeratosis and congestion occurred much more frequently on ventral surfaces.
