Characterization of NLRP3 isoforms in bullfrog Aquarana catesbeiana and their role in antibacterial immunity

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract The NLRP3 inflammasome is essential for innate immunity against pathogens, yet its function in amphibians remains poorly understood. Here, we identified and cloned two novel isoforms of NLRP3 from the American bullfrog (Aquarana catesbeiana), designated AcNLRP3 X1 and AcNLRP3 X2, with open reading frames of 2397 bp (798 aa) and 2874 bp (957 aa)

La introducción y el cultivo de la rana toro (Rana catesbeiana). ¿Un atentado a la biodiversidad de México?

Ciencia Ergo Sum, 2001
Se analiza el efecto que la introducción y el cultivo de la rana toro (Rana catesbeiana) ha tenido en el ecosistema y la biodiversidad en México. Se recomienda el cultivo de especies nativas para sustituir a la rana toro.

Introduced bullfrog facilitates pathogen invasion in the western United States.

PLoS ONE, 2018
Batrachochytrium dendrobatidis (Bd), a causal agent of the amphibian fungal skin disease chytridiomycosis, has been implicated in the decline and extinction of over 200 species worldwide since the 1970s.

Host Genus and Habitat Use Shape the Distribution of Batrachochytrium dendrobatidis Lineages in a Hyper‐Diverse Tropical Amphibian Community

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Anthropogenic change has facilitated the spread of the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) in Brazil's Atlantic Forest, where two Bd lineages (Bd‐GPL and Bd‐Brazil) co‐occur. We successfully genotyped 252 Bd‐positive samples from a diverse amphibian assemblage spanning aquatic and terrestrial habitats and found that Bd lineage ...

Validation of aerial photogrammetry methods to measure body size, condition and mass in small cetaceans

The Journal of Physiology, Volume 604, Issue 5, Page 1788-1808, 1 March 2026.
Abstract figure legend Unoccupied aerial vehicle (UAV)‐based photogrammetry provides measurements equivalent to traditional hand measurements in bottlenose dolphins. Mass estimates derived from UAV measurements closely match the true body mass of live individuals.

Alterações histopatológicas em girinos de rã-touro alimentados com rações comerciais de diferentes níveis protéicos Histopathological alterations in bullfrog tadpoles fed commercial diets with three levels of crude protein

Revista Brasileira de Zootecnia, 2008
Realizaram-se necropsia e exame histopatológico de girinos de rã-touro (Rana catesbeiana) alimentados com rações comerciais formuladas com 32, 36, 45 ou 55% de proteína bruta (PB) visando estabelecer a relação entre o nível de proteína bruta da ração e a

Cloning and Expression of Cryptochrome2 in the Bullfrog (Rana catesbeiana)

Molecules and Cells, 2003
Cryptochromes (CRYs) are non-opsin photoactive pigments that have recently been implicated in circadian photo-entrainment in humans, mice and Drosophila. In order to study the mechanism of circadian rhythm in amphibians, we have cloned and characterized a Rana cryptochrome in the bullfrog.
