What snakes are venomous in the US?

Venomous snakes found in the United States include rattlesnakes, copperheads, cottonmouths/water moccasins, and coral snakes. A venomous bite is called an “envenomation.” Although death from venomous snake bites is rare, a worker with a severe envenomation or allergy to snake venom can die from a venomous bite.

What are the four types of venomous snakes?

These four types of snakes are rattlesnakes, copperheads, cottonmouths, and coral snakes. If a snake is venomous in the United States, it is one of these four. Rattlesnakes make up the vast majority of all venomous snakes by sheer number.

How many people are killed by snakes each year?

VENOMOUS SNAKES. Although rare, some workers with a severe allergy to snake venom may be at risk of death if bitten. It has been estimated that 7,000–8,000 people per year receive venomous bites in the United States, and about 5 of those people die. The number of deaths would be much higher if people did not seek medical care.

How dangerous are the snakes in Vietnam?

Vietnam has many snake species, including venomous ones such as cobras, banded kraits and vipers. Bites by these species can cause instant death. Each year, more than 300,000 people are bitten by venomous snakes and treatment in hospitals is expensive.

Is there a cure for all snake venom?

While these are all useful precautionary measures, the ultimate treatment for a snake bite is antivenom. Try to get the victim of the bite antivenom as quick as possible. Knowing the size, color and shape of the snake can help your doctor determine which antivenom is best for that particular situation.

Is there an antidote for all snake bites?

Antivenom should be ideally administered within 4 h of the bite, but is effective even if given within 24 h. The dosage required varies with the degree of envenomation.

What is the current accepted treatment for snake bite?

With the correct treatment (antivenin), you can prevent severe illness or death. Antivenin, also called antivenom, is a treatment specific to the venom of a particular animal or insect.

How many snakes are medically important?

For many decades, the concept of the “Big 4” Snakes of Medical Importance has reflected the view that 4 species are responsible for Indian snakebite mortality—the Indian cobra (Naja naja), the common krait (Bungarus caeruleus), the Russell's viper (Daboia russelii) and the saw-scaled viper (Echis carinatus).

Why can humans only be treated with antivenom once?

Antivenom cannot reverse the effects of venom once they've begun, but it can prevent it from getting worse. In other words, antivenom cannot un-block a channel once it's already been blocked. Over time, your body will repair the damage caused by the venom, but antivenom can make it a much smaller repair job.

Can you survive a rattlesnake bite without treatment?

If you're bitten by one it can be dangerous, but it's very rarely fatal. However, if left untreated, the bite may result in severe medical problems or can be fatal.

Do hospitals carry antivenom?

Dr. McCorkle said most large hospitals have the anti-venom stocked and ready to go.

How do people survive snake bites without antivenom?

AdvertisementMove beyond the snake's striking distance.Remain still and calm to help slow the spread of venom.Remove jewelry and tight clothing before you start to swell.Position yourself, if possible, so that the bite is at or below the level of your heart.Clean the wound with soap and water.

Is there a medicine for snake bite How is it made?

If the situation is life threatening, the doctor may administer antivenom. This is a substance created with snake venom to counter the snake bite symptoms. It's injected into the victim. The sooner the antivenom is used, the more effective it will be.

How is antivenom produced in India?

The first antivenom was developed in 1895 by Albert Calmette against the Indian Cobra. In India, only horses are used for antibody production and the venom utilised is a combination of those collected from the 'Big Four' species — the spectacled cobra, common krait, Russell's viper, and saw-scaled viper.

Where is the most venomous snake in the world?

The coastal taipan is found in coastal regions of Northern and Eastern Australia and the nearby island of New Guinea. It produces venom that is almost identical to that of the inland taipan – considered to be the most venomous snake in the world.

What is neurotoxicity in snakes?

Neurotoxicity is a well-known feature of snake envenomation. Neurotoxins were first purified from snake venoms approximately 50 years ago. The majority of the neurotoxins (e.g., ion channel blockers and membrane receptor blockers) act on the peripheral nervous system where the skeletal neuromuscular junction is a favorite target. Neurotoxins lead to acute neuromuscular paralysis, a cause of morbidity and mortality [98]. This has been understood to be a mechanism of action for toxins in Elapidae snake venoms to include that form kraits (Bungarusspecies), cobras (Najaspecies), death adders (Acanthophisspecies), taipans (Oxyuranusspecies), coral snakes (Micrurusspecies), and tiger snakes (Notechisspecies) [99,100]. Recently, this has also been discovered in Viperidae snake venoms to include that of rattlesnakes (Crotalusspecies). Neurotoxicity is well known in envenoming by viper snakes to include Russell’s viper (Daboia russelii), asp viper (Vipera aspis), adder (Vipera berus), and nose-horned viper (Vipera ammodytes) [101,102]. Traditionally, snake venom neurotoxins are known to produce two types of neuromuscular blockade: presynaptic (β-neurotoxins) and postsynaptic (α-neurotoxins) according to their site of action.

What are the functions of snake venom?

Animal venoms are used as defense mechanisms or to immobilize and digest prey. In fact, venoms are complex mixtures of enzymatic and non-enzymatic components with specific pathophysiological functions. Peptide toxins isolated from animal venoms target mainly ion channels, membrane receptors and components of the hemostatic system with high selectivity and affinity. The present review shows an up-to-date survey on the pharmacology of snake-venom bioactive components and evaluates their therapeutic perspectives against a wide range of pathophysiological conditions. Snake venoms have also been used as medical tools for thousands of years especially in tradition Chinese medicine. Consequently, snake venoms can be considered as mini-drug libraries in which each drug is pharmacologically active. However, less than 0.01% of these toxins have been identified and characterized. For instance, Captopril®(Enalapril), Integrilin®(Eptifibatide) and Aggrastat®(Tirofiban) are drugs based on snake venoms, which have been approved by the FDA. In addition to these approved drugs, many other snake venom components are now involved in preclinical or clinical trials for a variety of therapeutic applications. These examples show that snake venoms can be a valuable source of new principle components in drug discovery.

What are the functions of phospholipases in snakes?

Phospholipases A2(PLA2s) enzymes, which play essential roles in various biological activities, are common to many snake venoms. Phospholipases are a class of enzymes that have the ability to hydrolyze specific substrates like glycerophospholipids. To date, they are recognized to be in four families A1, A2, C, and D. This classification identifies the site of hydrolysis on the substrate [57]. Among these families, PLA2s are the best studied due to their wide distribution in nature and PLA2s have been classified into more than 15 groups including several subgroups [58]. In the case of snakebites, PLA2enzymes play a significant role in the digestion of the prey in addition to a wide variety of other pharmacological effects by producing changes in the permeability of cell membranes by cleaving the sn-2 bond in glycerophospholipids to release free fatty acids and lysophospholipids [59,60]. PLA2s catalyze the Ca2+-dependent hydrolysis of the acyl ester at the sn-2 position of glycerophospholipids. PLA2s have been identified in almost all snake venoms of Viperidae, Hydrophidae, and Elapidae families [61].

What are SVSPs in snakes?

Snake venom serine proteinases (SVSPs) are present mainly in the venoms of Viperidae, Crotalidae, Elapidae, and Colubridae snakes and are more rarely detected in the venoms of Hydrophiidae snakes [38]. SVSPs are well-studied venom enzymes affecting generally the hemostatic system. Individually, they are not considered lethal, but they contribute to the toxic effect when combined with other proteins of the venom [39,40]. Fundamentally, SVSPs can be categorized into different subtypes depending on their mode of action to include thrombin-like enzymes, kallikrein-like, plasminogen activators, platelet aggregation inhibitors, protein-C activators and prothrombin activators [41]. Snake venom thrombin-like enzymes (SVTLEs) possess coagulant activities similar to thrombin but are not inhibited by heparin and they do not activate the blood coagulation factor XIII [29]. They convert fibrinogen to fibrin by the cleavage of the Aα and Bβ chains and in vitro increase clotting. However, in vivo, they have alternative effects to include hemostasis and anticoagulation [42]. To date, a large number of studies have led to the isolation and identification of TLEs mainly from the venom of the subfamilies Viperinae and Crotalinae [43]. Many TLEs have been isolated, such as Ancrod isolated from Agkistrodon rhodostoma[44], Crotalase purified from Crotalus adamanteus[45], ABUSV-SPase characterized from Agkistrodon blomhoffii ussurensis[46], Calobins isolated from Agkistrodon caliginosus[47], Elegaxobin purified from Trimeresurus elegans[48] and BjussuSP-I from Bothrops jararacussu[49]. Kallikrein-like serine proteases cause release of bradykinin from the high molecular weight kininogen and the degradation of angiotensin [50].

What are the biological properties of snake venom?

The summated biological properties of snake venoms closely follow that of their constituent components. Several snake venom components including PLA2, serine proteases, metalloproteinase, lectins, l-amino-acid oxidases, bradykinin potentiating factors, natriuretic factors, and integrin antagonists have valuable natural pharmacological actions that induce neurotoxicity, myotoxicity, cytotoxicity, hemotoxicity, and antimicrobial activity [2,97]. In general, snake venom components interact with a wide variety of mammalian proteins and can disrupt the central and peripheral nervous systems, the blood coagulation cascade, the cardiovascular and neuromuscular systems, and the general homeostasis state.

How many venomous animals are there in the world?

Venomous animals distribute in several regions around the world especially in tropic and subtropics regions. It is now accepted that there are more than 100,000 venomous animal species throughout the world. Only a very small fraction of these animals have been studied with regard to their venom composition [13]. Most of the venomous animal species are found in multiple phyla such as Chordata (reptiles, fishes, and amphibians), Arthropod (arachnids and insects), Mollusca (cone snails), Echinodermata (starfishes and sea urchins), and Cnidarian (sea anemones, jellyfish and corals) [14]. Furthermore, venomous animals are defined as those that inject their venoms into other living organisms using different apparatus such as spurs, stingers, spines, or fangs [15]. Venoms are secreted and delivered through well-developed venom exocrine glands and coupled to a delivery system, which have different vital functions for these animals that include capturing, killing and digesting prey, but they can also be considered as a defense mechanism against potential enemies [16]. Snakes are known as a subject of fascination, fear, and folk stories throughout history. The cobra was worshipped in ancient Egypt, and Roman emperors used the form of the cobra to decorate their crowns. All snakes are classified within the suborder Serpentes of the reptilian order Squamata, named for their scaly skin [17]. The two major infraorders Scolecophidia and Alethinophidia include around 3600 species located in approximately 27 families (Figure 2). The superfamily Colubroidea (>2500 species) are known today as advanced snakes and includes the majority of snake species [18]. Colubroidea includes several families including Viperidae, which contains around 331 species of vipers and pit viper snakes. It is the most prevalent family of venomous snakes with distribution throughout Europe, Africa, Asia, and the Americas, but absent in Australasia. Elapidae consists of 358 species of kraits, corals, mambas, and cobra snakes. Elapidae snakes are distribute worldwide with representatives in Africa, the Americas, Asia, and Australasia. However, they are most abundant in tropical and subtropical regions. Colubridae contains about 847 species of rear-fanged and harmless colubrid. It is widely distributed in all parts of the world. Lamprophiidae includes 309 species of Stiletto snakes and mole vipers. These are found in Africa, Asia, Europe and the Americas (http://www.reptile-database.org).

How many species of animals have venom?

There are more than 100,000 venomous animal species identified in the world. Each of these species is capable of producing venoms that often contain upwards to 100 different molecules. Animal venoms are used effectively for defense and predation. Animal venoms are not composed of single toxins but cocktails of complex chemical mixtures of pharmacologically active components including proteins, peptides, and enzymes with specific biological activities, as well as some non-protein compounds such as carbohydrates, lipids, metal ions and other, as yet, unidentified substances [1]. However, venom toxicity is generally linked to few toxins within the venom [2]. Bites or stings by certain venomous animals can result in acute envenomation leading to death [3]. According to the World Health Organization (WHO) recommendation, the most effective treatment for envenomation is the use of an antivenom serum [4]. To enhance the efficacy of such managements, a better information about venom composition is required.
