Venom composition

Figure 1: Composition of A.p.leucostoma venom, studied at proteomic level (Lomonte, et al., 2014 ). This venom contains the following families: SVMP (venom metalloproteinase ), serine protease (peptidase S1 ), peptides (include tripeptide SVMP inhibitors and bradykinin-potentiating and bradykinin-inhibitory peptides), LAAO (L-amino-acid oxidase (flavin monoamine oxidase) ), disintegrin, snaclec (also known as C-type lectin-like), CRISP, PA2 (phospholipase A2 ).

Clinical Effects, Treatment, Antivenoms See the Clinical Toxinology Resources Website
and the WHO venomous snake database to access snake distribution and antivenom products.

Lethal dose LD(50) of A.piscivorus is
6.24 mg/kg by intraperitoneal injection and
5.13 mg/kg by intravenous injection (Arce et al., 2003 ).
