First record of the chytrid fungus in Lithobates catesbeianus from Argentina: exotic species and conservation Primer registro del hongo quitridio en Lithobates catesbeianus de Argentina: especies exóticas y conservación

open access: yesRevista Mexicana de Biodiversidad, 2011
Chytridiomycosis, a disease caused by the chytrid fungus Batrachochytrium dendrobatidis (B.d.), is recognized as one of the major factors of amphibian decline. Global trade of amphibians has been identified as one of the causes of B.d.

Preparing for a Bsal invasion into North America has improved multi-sector readiness

open access: yesFrontiers in Amphibian and Reptile Science
Western palearctic salamander susceptibility to the skin disease caused by the amphibian chytrid fungus Batrachochytrium salamandrivorans (Bsal) was recognized in 2014, eliciting concerns for a potential novel wave of amphibian declines following the B ...

Emergence of Ophidiomyces ophidiicola, Nannizziopsis barbatae and Paranannizziopsis in free‐ranging Australian reptiles

open access: yesAustralian Veterinary Journal, Volume 104, Issue 6, Page 376-384, June 2026.
Emerging fungal diseases pose a threat to reptiles globally. Increasing detections of onygenalean fungi, particularly Ophidiomyces ophidiicola, Nannizziopsis spp. and Paranannizziopsis spp. in clinically diseased free‐ranging reptiles, indicate likely ongoing spread within wild reptile populations.

The amphibian‐killing fungus in a biodiversity hotspot: identifying and validating high‐risk areas and refugia

open access: yesEcosphere, 2019
Amphibian chytridiomycosis, due to infection with the fungus Batrachochytrium dendrobatidis (Bd), has been associated with the alarming decline and extinction crisis of amphibians worldwide. It is essential for conservation management to identify regions

A bibliometric-mapping approach to identifying patterns and trends in amphibian decline research

open access: yesActa Herpetologica, 2020
Amphibian decline is one of the most severe and well-documented examples of immediacy of the ongoing biodiversity crisis. In this study we analyze the scientific literature on amphibian declines with a view to identifying and analyzing emerging patterns ...

Host Abundance Predicts Interactive Roles in Neotropical Bat–Bat Fly Interactions

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We analyzed the influence of bat functional traits on their importance as hosts in bat–bat fly networks. Our results indicate that bat abundance is the main driver for host importance in Neotropical bat–bat fly interactions. ABSTRACT Host functional traits are known to shape host‐parasite interactions across multiple taxa.

Amphibian disease and declines: Chytridiomycosis [PDF]

open access: yesMicrobiology Australia, 2005
Chytridiomycosis is caused by Batrachochytrium dendrobatidis, a unique fungal organism of the phylum Chytridiomycota, a large group of ubiquitous fungi better known as silent digesters of organic waste or as parasites of nematodes and unicellular organisms such as pollen or algae. Chytr is the Greek root for earthen pot, Batracho ? frog and dendrobates

Assessing Genetic Diversity and Inbreeding Effects in an Endangered Amphibian: Effects of Ecological Restoration and Stochasticity

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study evaluated the genetic health of the endangered Rawlinsonia littlejohni following habitat modification and climatic variability. We identified two genetically distinct sub‐populations separated by limited gene flow, with heterozygosity remaining higher and inbreeding lower in the northern sub‐population containing both natural and constructed

Emerging Pathogen in Wild Amphibians and Frogs (Rana catesbeiana) Farmed for International Trade

open access: yesEmerging Infectious Diseases, 2003
Chytridiomycosis is an emerging disease responsible for global decline and extinction of amphibians. We report the causative agent, Batrachochytrium dendrobatidis, in North American bullfrogs (Rana catesbeiana) farmed for the international restaurant ...
