UNLABELLED We report a genus-wide comparison of venom proteome variation across New World pit vipers in the genus Agkistrodon. Despite the wide variety of habitats occupied by this genus and that all its taxa feed on diverse species of vertebrates and invertebrate prey, the venom proteomes of copperheads, cottonmouths, and cantils are remarkably similar, both in the type and relative abundance ...

Since the haemolysins of the several venoms respond differently to photodynamic action, they may be regarded as possessing different chemical constitutions. As regards stability, cobra haemolysin ranks first, daboia second, and Crotalus third. The toxicity of all the venoms is more or less diminished by eosin and erythrosin in sunlight. This reduction in toxicity depends upon chemical changes, ...

In this study, Mesobuthus gibbosus and Mesobuthus eupeus eupeus venom samples were compared for lethality, in vivo effects and proteins. Neutralization capacity of monovalent Androctonus crassicauda antivenom (RSHA anti-Ac) was tested against the lethal effects of the venoms.Venom was obtained from mature scorpions by electrical stimulation of the telson. The lethality of the venom and potency ...

Snake envenomation has been estimated to affect 1.8 million people annually with about 94,000 deaths mostly in poor tropical countries. Specific antivenoms are the only rational and effective therapy for these cases. Efforts are being made to produce effective, affordable and sufficient antivenoms for these victims. The immunization process, which has rarely been described in detail, is one ste...

BACKGROUND Burkholderia pseudomallei are the causative agent of melioidosis. Increasing resistance of the disease to antibiotics is a severe problem in treatment regime and has led to intensification of the search for new drugs. Antimicrobial peptides are the most ubiquitous in nature as part of the innate immune system and host defense mechanism. METHODS Here, we investigated a group of veno...
