Rações comerciais e o rendimento de carcaça e subprodutos de rã-touro Commercial food and the carcass yield and by-products of bullfrog

Ciência Rural, 2005
Objetivou-se avaliar o efeito do sexo e do uso de quatro rações comerciais extrusadas (R1, R2, R3 e R4) e uma ração peletizada (R5) sobre o rendimento de carcaça e aproveitamento de subprodutos da ranicultura, após 56 dias de experimentação.

New insights in gill/buccal rhythm spiking activity and CO2 sensitivity in pre- and post-metamorphic tadpoles (Pelophylax ridibundus)

, 2013
Central CO2chemosensitivity is crucial for all air-breathing vertebrates and raises the question of itsrole in ventilatory rhythmogenesis. In this study, neurograms of ventilatory motor outputs recorded infacial nerve of premetamorphic and ...

Non-O1/O139 Vibrio cholerae causes severe intestinal disease in bullfrogs (Rana catesbeiana)

Animal Diseases, 2023
Bullfrogs (Rana catesbeiana) are amphibians with high economic value, but in recent years, bullfrog farming has encountered serious threats of bacterial diseases, and the “bullfrog economy” is facing a continuous decline.

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)

Structure of the saxiphilin:saxitoxin (STX) complex reveals a convergent molecular recognition strategy for paralytic toxins. [PDF]

, 2019
Dinoflagelates and cyanobacteria produce saxitoxin (STX), a lethal bis-guanidinium neurotoxin causing paralytic shellfish poisoning. A number of metazoans have soluble STX-binding proteins that may prevent STX intoxication.

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 ...

Atividade da amilase em rã-touro durante a fase pós-metamórfica Amylase activy in the bulfrog during the post-metamorphic phase

Pesquisa Agropecuária Brasileira, 2005
O objetivo deste trabalho foi avaliar a atividade da amilase no quimo da rã-touro, Rana catesbeiana Shaw 1802 (3,6 a 200 g). Oitenta e sete animais foram distribuídos em baias-testes com temperatura e fotoperíodo controlados.
