Survival of Batrachochytrium dendrobatidis in Water: Quarantine and Disease Control Implications

Emerging Infectious Diseases, 2003
Amphibian chytridiomycosis is an emerging infectious disease of amphibians thought to be moved between countries by trade in infected amphibians. The causative fungus, Batrachochytrium dendrobatidis, produces aquatic, motile zoospores; infections have ...

Temporal Variation of the Skin Bacterial Community and Batrachochytrium dendrobatidis Infection in the Terrestrial Cryptic Frog Philoria loveridgei

Frontiers in Microbiology, 2017
In animals and plants, symbiotic bacteria can play an important role in disease resistance of host and are the focus of much current research. Globally, amphibian population declines and extinctions have occurred due to chytridiomycosis, a skin disease ...

Chytridiomycosis-induced mortality in a threatened anuran

PLOS ONE, 2020
Effectively planning conservation introductions involves assessing the suitability of both donor and recipient populations, including the landscape of disease risk. Chytridiomycosis, caused by the fungal pathogenBatrachochytrium dendrobatidis(Bd), has caused extensive amphibian declines globally and may hamper reintroduction attempts.

Localized carry‐over effects of pond drying on survival, growth, and pathogen defenses in amphibians

Ecosphere, 2022
Climate change is increasing variability in precipitation patterns in many parts of the globe. Unpredictable changes in water availability can be particularly challenging for organisms that rely on precipitation‐fed water sources for completing their ...

Integrating infection intensity and aggregation into the dynamics of pathogens with within‐host replication

Journal of Animal Ecology, EarlyView.
We bridge micro‐ and macroparasite theory with a model tracking pathogen load heterogeneity. By incorporating load‐dependent mortality and within‐host pathogen growth, we show how pathogen load aggregation alters disease prevalence, host suppression effects, and virulence evolution, providing insights for managing complex infectious disease like ...

Application of the survey protocol for chytridiomycosis to Queensland, Australia [PDF]

Diseases of Aquatic Organisms, 2010
Spread of the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd), which causes chytridiomycosis, has resulted in the extinction of frogs, but the distribution of Bd is incompletely known. We trialled the survey protocol for Bd by attempting to systematically map its distribution in Queensland, Australia.

Continent-wide recent emergence of a global pathogen in African amphibians

Frontiers in Conservation Science, 2023
IntroductionEmerging infectious diseases are increasingly recognized as a global threat to wildlife. Pandemics in amphibians, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), have resulted in biodiversity loss at a global scale. Genomic

Spillover dynamics and asynchronous temporal fluctuations in host density and competence drive fungal parasite persistence in multi‐host, seasonal communities

Journal of Animal Ecology, EarlyView.
In this study, the authors develop a new model to show that species contributions to parasite persistence can have strong, asynchronous temporal variability, often limiting the effectiveness of targeted seasonal parasite control. The model is broadly applicable for partitioning who, when, and what drive parasite persistence in multi‐host seasonal ...

Seasonality of host immunity in a tropical disease system

Ecosphere, 2022
Infectious disease systems frequently exhibit strong seasonal patterns, yet the mechanisms that underpin intra‐annual cycles are unclear, particularly in tropical regions.

Impact of climate on Australian, non‐Vector‐borne infectious animal diseases: A scoping review

Australian Veterinary Journal, EarlyView.
Changes to Australia's climate continue to be increasingly relevant for human, animal and planetary health, and have far‐reaching impacts on disease emergence and food security. There is a deficit of knowledge in Australia around how climatic conditions are affecting infectious animal diseases, beyond the more obvious spatial distribution changes of ...
