Venom composition image
Figure 1: Composition of contortrix contortrix 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), NGF (-beta) , CRISP, oha (ohanin/vespryn), DC-fragments (disintegrin/cysteine-rich fragment from P-III SVMPs) and PA2 (phospholipase A2).

Clinical Effects, Treatment, Antivenoms See the Clinical Toxinology Resources Website.
Lethal dose LD(50) of A.contortrix is
9.17 mg/kg by intraperitoneal injection and
