“…B. leucurus was responsible for all cases of envenomation from snakebite recorded in the metropolitan region of Salvador (State of Bahia, northeastern Brazil) from January to June 1990 (Lira-da- Silva and Nunes, 1993) and an epidemiological study in Bahia in 2001 revealed that this species was responsible for all confirmed cases of envenomation by Bothrops species in this state (Mise et al, 2007). Recently, active components from B. leucurus venom were isolated, including a fibrinolytic proteinase (Bello et al, 2006), a thrombin-like enzyme (Magalhães et al, 2007), phospholipase A 2 (Higuchi et al, 2007), a P-III metalloproteinase (Sanchez et al, 2007), L-amino acid oxidases (Silva et al, 2007;Torres et al, 2010) as well as the metalloproteinases leucurolysin-a (Gremski et al, 2007;Ferreira et al, 2009) and BleucMP (Gomes et al, 2011).…”
