| Abstract Background Snakebite treatment requires administration of an appropriate antivenom that should contain antibodies capable of neutralizing the venom. To achieve this goal, antivenom production must start from a suitable immunization protocol and proper venom mixtures. In Brazil, antivenom against South American rattlesnake (Crotalus durissus terrificus) bites is produced by public institutions based on the guidelines defined by the regulatory agency of the Brazilian Ministry of Health, ANVISA. However, each institution uses its own mixture of rattlesnake venom antigens. Previous works have shown that crotamine, a toxin found in Crolatus durissus venom, shows marked individual and populational variation. In addition, serum produced from... |

| This paper reports the preliminary results of two years of herpetogeographic studies in the region called «Grande Porto Alegre» at its northern portion. The physiognomy shows, at North, slopes of the Brazilian Southern Plateau, more or less forested in a general view; these elevations graãuálly decrease to the South until the levei of the sea to Atlantic littoral by the eastern border, and to Rio Grande do Sul savanah, which extends to Uruguay and Argentina. The biota is transitional from the highland prairies and forests of the plateau to lowland prairies of the pampas. Three faunistic Provinces are included: Guarani, Pampean, and Tupi. The most conspicuous dispersion is shown by the taxa proceeding from the plateau to savanah (Dispersion Centre Guarani);... |
