Gene expression differs in susceptible and resistant amphibians exposed to Batrachochytrium dendrobatidis. [PDF]
, 2018 Chytridiomycosis, the disease caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), has devastated global amphibian biodiversity. Nevertheless, some hosts avoid disease after Bd exposure even as others experience near-complete extirpation ...

Oxidative phosphorylation efficiency, proton conductance and reactive oxygen species production of liver mitochondria correlates with body mass in frogs [PDF]
, 2015 ody size is a central biological parameter affecting most biological processes (especially energetics) and mitochondria is a key organelle controlling metabolism and is also the cell's main source of chemical energy.

Perichordal Vertebral Column Formation in Rana kobai. [PDF]
J MorpholIn contrast to the previous study, centrum formation begins with a pair of ossification centers at the base of neural arches in Rana. At the early stage of intervertebral disc formation, a wedge‐like cartilage domain is observed posteroventral to the centrum. Evolutionary implications are discussed based on these observations.

Micronuclei induction in Rana catesbeiana tadpoles by the pyrethroid insecticide lambda-cyhalothrin
Genetics and Molecular Biology, 2003 Pyrethroid lambda-cyhalothrin genotoxicity was evaluated using the micronucleus test in Rana catesbeiana tadpoles. The effects of concentration and exposure time on the micronuclei frequency were studied in blood smears obtained from tadpoles exposed to ...

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.

Pathogenic fungus in feral populations of the invasive North American bullfrog in Argentina [PDF]
, 2017 Nearly a third (32.4%) of the world?s amphibian species are either threatened with extinction or already extinct (1). The chytrid fungus Batrachochytrium dendrobatidis (Bd) (Chytridiomycetes: Ryzophydiales) (2) has been recognized as responsible for mass
