Platypus Envenomation

Platypus Envenomation Summary The duck (Ornithorhynchus anatinus) who requested a duck ordered from Monotrema is found in the river system in eastern Australia. Men have a retractable spur in each hind leg. The spur attaches to the venom gland and produces a toxic mixture of at least four different classes of peptides. These four compounds (hyaluronidase, OvCNP-39, OvNGF, and defensin-like peptides) are highly selective enzymes and peptides and can work together to cause intolerable pain and edema and can persist for several months .

Five million people are bitten by snakes every year around the world. Among them, poison (purchased) snakes can cause considerable morbidity and mortality. There are 400,000 poisons (poison bite) and 94 000 to 125 000 deaths each year, there are other serious health hazards such as cutting and infection of 40000 people, tetanus, scarring, contractures and psychological sequelae It is presumed. . Insufficient access to healthcare and lack of antitoxin serum increases the severity of the injury and its effect

About 600 snakes are toxic, and about 50 to 70% bite is caused by these poisons. When taking a bite, the cornerstone of care is to fix the affected body part completely and transfer them to the medical facility soon. Do not use the tourniquet or cutting wound as a first aid because there is a possibility that the influence of poison may be exacerbated. Victims of snake bite need to be treated with antitoxin often. Importantly, antitoxin is suitable for region-specific snakes. Other measures include supportive care such as wound cleansing, airway support to reduce the risk of infection, and immunization against tetanus at discharge when the patient is not vaccinated against tetanus

Note: Not all toxic snake bites are correct. However, any animal bites are at risk of tetanus, and anyone suffering from snake bite should seek medical assistance. Antitoxin sera can not be cured, they are just aid to the treatment of bites. The above mortality rate is for intestinal bites, the death rate is 2%, the mortality rate is 2 to 5%, the mild is 5 to 15%.

How to bite: The snake injecting the venom uses the modified salivary glands. Poison is a modified form of saliva that may evolve to aid chemical digestion. Different degrees of toxicity can also help kill prey. In the venom (infusion of venom or poison bite), the venom enters the snake's fang through the catheter from the venom gland and finally enters the prey. Snake venom is a combination of many substances with different actions. Briefly, these proteins can be divided into four categories.
