The majority of rabbits receiving intradermal, intraperitoneal or intravenous injections of moccasin venom became refractory to the development of the Shwartzman phenomenon. An incubation period of about 14 days was required for their resistance to develop. The incidence of refractory animals was inversely proportional within limits to the amount of toxin given intravenously to elicit the Shwar...

Snakebite envenomation is a neglected global health problem, causing substantial mortality, disability, and psychological morbidity, especially in rural tropical and subtropical zones. Antivenin is currently the only specific medicine for envenomation. However, it is restricted by cold storage, snakebite diagnosis, and high price. Snake venom phospholipase A2s (svPLA2s) are found in all kinds o...

General overview Australia is home to some of the most venomous creatures in the world. T has been undertaken on many of these venoms. The focus of our group is and biochemical examination of venoms from Australasian animals. We a in: examining whether the currently available antivenoms can be utilise other species (some closely related while others are not). We are also inte primary mode of ac...

There are approximately 28 species of Aerva genus, but only a few species are medicinal of which A. persica, A. lanata and A. javanica are of great value. A number of flavonol glycosides (e.g., aervanone, kaempferol-3-galactoside, isorhamnetin-3-O-β-D-glucoside) have been reported from Aerva persica as major phytoconstituents and the minor constituents are β-cyanins (glycine betaine and trigone...

This article focuses on the medically relevant arachnid species found in North America and selected other arachnids from around the world. While it is largely still true that the geographic location of the envenomation assists in determining the species responsible, the booming trade in arachnids as exotic pets should prompt the clinician to inquire into this possibility. Expert advice should b...

Snakebite envenoming constitutes an important public health problem in Latin America and some countries of the Caribbean. The advances and pending tasks in the study and control of this neglected tropical disease in this region are reviewed in the light of a roadmap proposed in 2006. Significant progress has been achieved in the study of snake venoms, particularly regarding venom proteomics, i....

Non-native (exotic) snakes are a problematic source of envenomation worldwide. This manuscript describes the current demographics, outcomes and challenges of non-native snakebites in the United States (U.S.). We performed a retrospective case series of the National Poison Data System (NPDS) database between 2005 and 2011. There were 258 human exposures involving at least 61 unique exotic venomo...

We report a case of severe rapid-onset paralysis in a 28- year-old previously healthy man, necessitating intubation and mechanical ventilation, after a presumed bite or sting. Despite no other systemic manifestations of envenoming, the paralysis rapidly responded to polyvalent snake antivenom. The rapidity and severity of clinical effects make this case most concerning. We outline a differentia...
