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

open access: yes, 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.

Variability of Rheotaxis Behaviors in Larval Bullfrogs Highlights Species Diversity in Lateral Line Function. [PDF]

open access: yesPLoS ONE, 2016
The morphology and distribution of lateral line neuromasts vary between ecomorphological types of anuran tadpoles, but little is known about how this structural variability contributes to differences in lateral-line mediated behaviors.

Vestibular Syndrome Associated to Ranavirus in Farmed American Bullfrogs

open access: yes, 2021
Abstract Frog farming is a consolidated aquaculture activity in Brazil. American bullfrogs (Lithobates catesbeianus) are raised in high densities and fed artificial diets, conditions that favors the emergence of diseases. A common disease affecting farmed frogs is a nervous syndrome characterized by postural and locomotive alterations resembling a ...
