The medical importance of the largest discrete and polyphyletic group of snakes, referred to previously as the family Colubridae for convenience, is verified only for a handful of the approximately 2,000–2,500 taxa in this diversified and taxonomically artificial assemblage (Warrell, 2004; Weinstein and Kardong, 1994; Weinstein et al., 2010). Some primarily eat amphibians and fish, while others eat rodents. Potential symptoms include tissue destruction, paralysis, and extensive bleeding. The dose and exposure to venom vary due to the complexity of multiple components, the amount injected, and the type of snakebite. They are called Elapids, Constrictors, Vipers, Boas and Pythons, and Colubrids. The clinical relevance of other colubrid taxa [e.g., Malpolon monspessulanus (Montpellier snake; Gonzáles, 1979; Pommier and De Haro, 2007), Boiga irregularis (brown tree snake; Fritts and McCoid, 1999; Fritts et al., 1990, 1994)] is supported by relatively limited evidence.

All the venomous species belong to the families Elapidae, Hydrophiidae, Viperidae, Crotalidae, Colubridae, and Atractaspididae. , Natricinae – 37 genera (sometimes given as family Natricidae), Dipsadinae – 99 genera (sometimes given as family Dipsadidae), Unknown incertae sedis (not currently placed in a subfamily, usually because of the absence of genetic data, but suspected to be colubrids based on morphology).  In other words, constriction can work by different mechanisms at varying pressures. Farmers keep the snake around their fields and storage sheds to reduce the rodent populations. Colubrid snakes are found on every continent except Antarctica. Areflexia, ataxia, and ophthalmoplegia can be noted in the rarer Miller Fisher syndrome (Longmore et al., 2001). and Saviola, A.J., 2007. The patient was initially treated with antibiotics and steroids, and provided with tetanus toxoid. Yes, Ovophis are a genus of constricting vipers from Asia. Alisa N. Reniker, in Handbook of Small Animal Practice (Fifth Edition), 2008. The snake will then wrap one or two loops around the prey, forming a constriction coil. A cerebral spinal fluid (CSF) analysis was acellular, but with markedly elevated protein (110 mg/dL; Chroni et al., 2005). *There are 300 species of Elapids *They have short, sharp fangs that are fixed … Copyright © 2020 Elsevier B.V. or its licensors or contributors. Late Pleistocene mammals from a cave in Tamaulipas, Mexico. Thornton, in Encyclopedia of Toxicology (Third Edition), 2014. There are several venomous colubrids which use a combination of envenomation and construction to subdue their prey. Download yours today! Some of these neuropathies can be associated with comorbidities, but the authors asserted an unremarkable medical history of their patient (Chroni et al., 2005). 2001. Snakes within this family are commonly referred to as colubrids. 1996. Certain constricting patterns are used by most basal alethinophidians above uropeltids, including basal macrostomates (Greene and Burghardt, 1978). Acute polyradiculitis often initially presents as a paresthesia that begins from the lower extremities and develops into a symmetrically ascending myasthenia.
