Caracterização individual do veneno de Bothrops alternatus Duméril, Bibron & Duméril em função da distribuição geográfica no Brasil (Serpentes,Viperidae)

Abstract: Bothrops alternatus Duméril, Bibron & Duméril, 1854 é uma serpente de importância em saúde pública, com ampla distribuição geográfica, desde o Mato Grosso do Sul até o sudeste do Brasil, chegando até a Argentina e Uruguai, ocupando vários domínios morfoclimáticos. Neste trabalho investigou-se a variação do veneno de adultos de Bothrops alternatus, em função de sua distribuição geográfica no Brasil, comparativamente ao veneno elaborado sob a forma de "pool" desta espécie (veneno referência), que inclui serp… Show more

“…These results may strengthen the hypotheses of close similarity regarding the actions and activities of venom from the families Viperidae and Dipsadidae and may corroborate the eletrophoretic analysis performed by Rocha and Furtado [26] .…”

“…Some of these components disrupt vital physiological processes of preys (Ciscotto et al, 2011; Sanz et al, 2008; Tucker and Miletich, 2010) or act as defence against predators (Ciscotto et al, 2011; Kardong, 1982; Tucker and Miletich, 2010). Venom composition reflects not only evolutionary differentiation of phylogenetic lineages (Escoubas et al, 2008; Gutiérrez, 2011), but also distinct developmental stages, dietary behaviour and habitat variation (Ciscotto et al, 2011; Da Rocha and Furtado, 2005; Madrigal et al, 2012). As an example, adults L. stenophrys present higher abundance of snake venom metalloproteinases (SVMPs) and Gal-lectin than juvenile specimens, whereas serine proteinases and vasoactive peptides are lower in adult specimens than in juvenile ones (Madrigal et al, 2012).…”

“…This variability and complexity of venoms may be due to ontogenetic and geographic variations and has implications for the treatment of snakebites (Furtado, 1987;Chippaux, et al, 1991;Ohno, et al, 1998;Da Rocha, et al, 2005;. Herein, we observe that the local changes induced by the venom of both Eicosanoids are important vasoactive mediators and chemotactics derived from arachidonic acid.…”
