Snake Venom and Antivenom Pharmacology

Posted by
  SNAKE VENOM & ANTIVENOM Chemistry, Composition, Mechanisms and Pharmacology Abstract This integrated teaching session for Phase III MBBS students focused on the pharmacology and toxicology of snake venom and the principles of antivenom therapy. The lecture covered the chemistry, composition, mechanisms of action, and pharmacological effects of snake venoms and antivenoms. Rational use of antivenoms, indications, administration protocols, adverse reactions, and supportive management strategies were discussed. The session also highlighted the translational importance of venom-derived compounds in modern drug development. Recent advances in antivenom research, including recombinant human monoclonal antibodies, toxin-specific inhibitors, synthetic antibody technologies, and next-generation broad-spectrum antivenoms, were reviewed. Current discoveries and emerging approaches aimed at improving efficacy, safety, affordability, and accessibility of antivenom therapy were also explor...

Geographic distribution of Euathlus manicatus (Simon, 1892) (Araneae: Theraphosidae) in Chile: new localities and comments on the identity of the female described by Legendre & Calderón (1984)

Abstract


The geographical distribution of Euathlus manicatus in Chile is updated using data from scientific collections and records obtained through citizen science programs. From this analysis, 99 new localities were obtained for the country, extending the northern limit by more than 100 km to the locality of Topocalma (34°05’50’’ S, 71°55’11’’ W), in the the Libertador General Bernardo O’Higgins Region, while the southern limit extends approximately 230 km to the locality of Malalcahuello (38°28’49” S, 71°49’11’’ W), in the La Araucanía Region. Furthermore, based on new material collected, we consider that the female previously described and illustrated as E. manicatus by Legendre and Calderón, could have corresponded to that of this species.
