Global emergence of Batrachochytrium dendrobatidis and amphibian chytridiomycosis in space, time, and host.

- Environmental Science, BiologyAnnual Review of Microbiology
- 8 September 2009
This review explores the molecular, epidemiological, and ecological evidence that Bd evolved from an endemic ancestral lineage to achieve global prominence via anthropogenically mediated spread and considers the major host and pathogen factors that have led to the occurrence of chytridiomycosis in amphibian species, populations, and communities.
Multiple emergences of genetically diverse amphibian-infecting chytrids include a globalized hypervirulent recombinant lineage

- BiologyProceedings of the National Academy of Sciences
- 7 November 2011
It is postulate that contact between previously genetically isolated allopatric populations of Bd may have allowed recombination to occur, resulting in the generation, spread, and invasion of the hypervirulent BdGPL leading to contemporary disease-driven losses in amphibian biodiversity.
Recent introduction of a chytrid fungus endangers Western Palearctic salamanders

Results show that B. salamandrivorans is restricted to, but highly pathogenic for, salamanders and newts (Urodela), and likely originated and remained in coexistence with a clade of salamander hosts for millions of years in Asia.
Mapping the Global Emergence of Batrachochytrium dendrobatidis, the Amphibian Chytrid Fungus

It is shown that detected Bd infections are related to amphibian biodiversity and locations experiencing rapid enigmatic declines, supporting the hypothesis that greater complexity of amphibian communities increases the likelihood of emergence of infection and transmission of Bd.
The emerging amphibian pathogen Batrachochytrium dendrobatidis globally infects introduced populations of the North American bullfrog, Rana catesbeiana

- 22 September 2006
The bullfrog is the most commonly farmed amphibian, and escapes and subsequent establishment of feral populations regularly occur, which suggest that the global threat of B. dendrobatidis disease transmission posed by bullfrogs is significant.
Amphibian fungal panzootic causes catastrophic and ongoing loss of biodiversity
- B. Scheele, F. Pasmans, S. Canessa
- Environmental ScienceScience
- 28 March 2019
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.
Life history tradeoffs influence mortality associated with the amphibian pathogen Batrachochytrium dendrobatidis
- T. Garner, Susan F. Walker, M. Fisher

- 1 May 2009
The data show that amphibian survival in the face of challenge by an infectious agent is dependent on host condition as well as life history stage, and condition-dependent traits may weigh heavily on species survival.
Recent Asian origin of chytrid fungi causing global amphibian declines
- S. O'Hanlon, A. Rieux, M. Fisher

- 11 May 2018
Panzootic chytrid fungus out of Asia Species in the fungal genus Batrachochytrium are responsible for severe declines in the populations of amphibians globally. The sources of these pathogens have…
Proteomic and phenotypic profiling of the amphibian pathogen Batrachochytrium dendrobatidis shows that genotype is linked to virulence
The data show that, despite its rapid global emergence, Bd isolates are not identical and differ in several important characters that are linked to virulence, and argues that future studies need to clarify the mechanism and rate at which Bd is evolving, and the impact that such variation has on the host–pathogen dynamic.
Expression Profiling the Temperature-Dependent Amphibian Response to Infection by Batrachochytrium dendrobatidis
- L. Ribas, Ming-Shi Li, M. Fisher
- BiologyPLoS ONE
- 22 December 2009
The temperature-dependency of the amphibian response to infection by Bd is demonstrated and the influence that changing climates may exert on the ectothermic host response to pathogens is indicated.
