Popis: Cururu toad (Rhinella marina group) is widely distributed in Brazil. Lesser grison (Galitic cuja) is a South American mustelid. This is the first report of natural poisoning in a free-ranging lesser grison by Rhinella toad parotoid gland secretion (PGS). Five minutes after biting a toad, the lesser grison developed convulsion, dying within 1.5 h. Mass spectrometry analysis of a milky-whitish secretion found in the lesser grison oral cavity allowed identification of a bufotoxin and a new bufonid peptide.
