Tityus obscurus (Amazonian scorpion)

Venom composition image
Figure 1: Composition of T.obscurus venom, studied at the transcriptomic level. This venom contains the following families (classified by activity): sodium channel toxin (NaTx), anionic peptide, anticoagulant peptide (negligible), antimicrobial peptide (AMP), bradykinin potentiating-peptide (BPP), chitinase (negligible), CRISP, hyaluronidase, insulin-like growth factor, lipase, metalloproreinase, phospholipase A2 (PA2), phospholipase C (negligible), potassium channel toxin (KTx), proteinase inhibitor, other proteinase, conserved venom component (de Oliveira et al., 2018). Families with an asterix (*) are those with peptides identified by proteomic analysis.
Clinical Effects, Treatment, Antivenoms See the Clinical Toxinology Resources Website.
Lethal dose LD(50) is 3.13 mg/kg by intraperitoneal injection into mice (Santos da Silva et al., 2017).
