Although the chytrid fungus Batrachochytrium dendrobatidis (Bd), the etiological agent of amphibian chytridiomycosis, has been implicated in mass mortality and population declines on several continents around the world, there have been no reports on the presence of Bd infections in amphibians in China. We employed quantitative PCR and histological techniques to investigate the presence of Bd in introduced North American bullfrogs (Rana catesbeiana) (referred to hereafter as bullfrog) and native… 

Occurrence of the amphibian chytrid fungus Batrachochytrium dendrobatidis in introduced and native species from two regions of France

The presence of the chytrid fungus in amphibian populations from different locations in southwestern France calls for disease surveillance and for precautionary measures to avoid the spread of this emerging disease.

Retrospective Survey of Museum Specimens Reveals Historically Widespread Presence of Batrachochytrium dendrobatidis in China

The first evidence of Bd for Taiwan and the first detection in the critically endangered Chinese giant salamander are reported, suggesting that this pathogen has been more widely distributed in the last century than previously believed.

Filling a gap in the distribution of Batrachochytrium dendrobatidis: evidence in amphibians from northern China.

It is suggested that urgent implementation of measures is required to reduce the possibility of further spread or inadvertent introduction of Bd to China, and whether Bd in northern China belongs to endemic and/or exotic genotypes, and this should be the focus of future research.

Dynamics of Chytrid Fungus (Batrachochytrium Dendrobatidis) Infection in Amphibians in the Rincon Mountains and Tucson, Arizona

Patterns of Bd infection in Hyla arenicolor, Rana catesbeiana, and R. yavapaiensis in the Rincon Mountains and Tucson Basin in Arizona were studied to determine patterns of BD prevalence and infection intensity in both species, in different life stages, at different locations, and across elevations and seasons.

Emerging Chytrid Fungal Pathogen, Batrachochytrium Dendrobatidis, in Zoo Amphibians in Thailand

Skin swab samples revealed the typical feature of fl ask-shaped zoosporangia and septate thalli, supporting the PCR-based evidence of chytridiomycosis in captive amphibians in Thailand, but detected Bd in only 7/21 of thePCR-positive samples.

First Evidence of Amphibian Chytrid Fungus (Batrachochytrium dendrobatidis) and Ranavirus in Hong Kong Amphibian Trade

Rapid response efforts are now urgently needed to determine current pathogen distribution in Hong Kong, evaluate potential trade-associated exposure to free-ranging amphibians, and identify opportunities to prevent disease establishment.

Chytridiomycosis in Asian Amphibians, a Global Resource for Batrachochytrium dendrobatidis (Bd) Research

It is emphasized that chytridiomycosis in Asia is an important wildlife disease and it needs focussed research, as it is a dynamic front of pathogen diversity and virulence.

Batrachochytrium dendrobatidis prevalence and haplotypes in domestic and imported pet amphibians in Japan.

The results show that Bd is currently entering Japan via the international trade in exotic amphibians as pets, suggesting that the trade has indeed played a major role in the spread of Bd.

Survey of Turkey's endemic amphibians for chytrid fungus Batrachochytrium dendrobatidis.

This study reports the first records of Bd infecting wild Pelophylax ridibundus, Hyla orientalis, Pseudepidalea variabilis, and endemic Beysehir frogs Pelphylax caralitanus.

DISTRIBUTION, DIET, AND PREVALENCE OF AMPHIBIAN CHYTRID FUNGUS IN NON-NATIVE AMERICAN BULLFROGS (LITHOBATES CATESBEIANUS) AT THE VALENTINE NATIONAL WILDLIFE REFUGE, NEBRASKA, USA

Preliminary data indicate that bullfrogs likely have already affected interspecific interactions with native amphibians via predation, competition, and/or disease transmission, and expanding the season of harvest of bull frogs might reduce their abundance, which may benefit native amphibian and reptiles.

First detection of the amphibian chytrid fungus Batrachochytrium dendrobatidis in free-ranging populations of amphibians on mainland Asia: survey in South Korea.

Results confirm that Batrachochytrium dendrobatidis, the amphibian chytrid fungus causing this disease, is present in South Korea and, hence, on the Asian mainland.

Survey for the amphibian chytrid Batrachochytrium dendrobatidis in Hong Kong in native amphibians and in the international amphibian trade.

Until it is established that the pathogen Batrachochytrium dendrobatidis is present in Hong Kong, management strategies should focus on preventing it from being imported and decreasing the risk of it escaping into the wild amphibian populations if imported.

Historical Evidence of Widespread Chytrid Infection in North American Amphibian Populations

To investigate the global distribution, historical occurrence, and infectiousness of this pathogen, postmetamorphic and adult amphibians collected between 1895 and 2001 from 25 countries were examined for the presence of chytrid fungi in the epidermis.

Chytridiomycosis in frogs of Mount Gede Pangrango, Indonesia.

It is essential to manage Batrachochytrium dendrobatidis in Indonesia where it is likely to be threatening amphibian populations, and a national strategy to mitigate the spread of Bd in Indonesia and neighboring countries is required.

Transmission of Batrachochytrium dendrobatidis within and between amphibian life stages.

Experimental evidence is presented that R. muscosa tadpoles can be infected by fungal zoospores and that they can transmit infection to each other and to postmetamorphic animals.

The emerging amphibian pathogen Batrachochytrium dendrobatidis globally infects introduced populations of the North American bullfrog, Rana catesbeiana

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.

Latitudinal Variation in the Prevalence and Intensity of Chytrid (Batrachochytrium dendrobatidis) Infection in Eastern Australia

Small frogs were more likely to be infected and carried more intense infections than larger frogs, suggesting either that frogs can outgrow their chytrid infections or that the disease induces developmental stress that limits growth.
