Dogs envenomed with non-lethal doses of Bothrops alternatus venom received standard antivenom therapy, im injections of flunixin meglumine, or topical treatmentwith aqueous Curcuma longa plant extract. Biodistribution of the venom and antivenom were determined by ELISA. There was no significant difference in the efficacy of antivenom and plant extract on local effects; flunixin treatment had lower efficacy. Distribution of the venom was similar with all 3 treatments. Serum levels of the antivenom reached maximum 2-4 h after administration and were not detected after the 5th d.

Scorpion envenomation, especially from Hemiscorpius lepturus, poses a significant health risk, leading to considerable morbidity and mortality. The venom's major toxin, which includes phospholipase D (PLD), is responsible for various systemic complications. In prior studies, we identified a native phospholipase D (PLD) toxin as a key lethal factor in the venom of H.

Background: This is the first study to examine a cohort that engages in the practice of immunization with snake venoms. In this practice, either fresh wet venom or venom reconstituted from freeze-dried form is used in vaccination protocols to produce hyper-immunity to venom.
Methods: This is a retrospective community-initiated collaborative research (CICR) project that collated the records of venom immunization.

Antivenoms are the only effective treatment for snakebite envenomation and have saved countless lives over more than a century. Despite their value, antivenoms present risks of adverse reactions. Current formulations contain a fraction of nonspecific antibodies and serum proteins.

Snakebite envenoming remains a devastating and neglected tropical disease, claiming over 100,000 lives annually and causing severe complications and long-lasting disabilities for many more. Three-finger toxins (3FTx) are highly toxic components of elapid snake venoms that can cause diverse pathologies, including severe tissue damage and inhibition of nicotinic acetylcholine receptors, resulting in life-threatening neurotoxicity. At present, the only available treatments for snakebites consist of polyclonal antibodies derived from the plasma of immunized animals, which have high cost and limited efficacy against 3FTxs.
