Envenomation from a redback spider bite produces a syndrome known as latrodectism. A small but significant percentage of people bitten develop significant pain or systemic symptoms. [120] The diagnosis is made from the clinical condition, often based on the victim being aware of a bite and ideally with identification of the spider.
Latrodectus hasselti, the redback spider. The widow spiders (genus Latrodectus), such as the black widow, redback spider, and katipō are spiders that carry a neurotoxic venom [18] which can cause a set of symptoms known as Latrodectism. Widow spiders are large, shiny house spiders with relatively spindly legs and deep, globular abdomens.
There are no tests required to diagnose widow spider bites, or latrodectism symptoms. [4] [5] The diagnosis is clinical and based on historic evidence of widow spider bites. Pathognomonic symptoms such as localized sweating and piloerection provide evidence of envenomation. Diagnosis in most people includes reporting contact with a Latrodectus ...
A spider bite, also known as arachnidism, is an injury resulting from the bite of a spider. The effects of most bites are not serious. [1] Most bites result in mild symptoms around the area of the bite. [1] Rarely they may produce a necrotic skin wound or severe pain. [2]: 455 Most spiders do not cause bites that are of importance. [1]
Elsewhere, others include the European black widow (Latrodectus tredecimguttatus), the Australian redback spider (Latrodectus hasseltii) and the closely related New Zealand katipō (Latrodectus katipo), several different species in Southern Africa that can be called button spiders, and the South American black-widow spiders (Latrodectus ...
A spider envenomation occurs whenever a spider injects venom into the skin. Not all spider bites inject venom – a dry bite, and the amount of venom injected can vary based on the type of spider and the circumstances of the encounter. The mechanical injury from a spider bite is not a serious concern for humans.
Envenomation is the process by which venom is injected by the bite or sting of a venomous animal. [ 1 ] Many kinds of animals, including mammals (e.g., the northern short-tailed shrew , Blarina brevicauda ), reptiles (e.g., the king cobra ), [ 2 ] spiders (e.g., black widows ), [ 3 ] insects (e.g., wasps ), and fish (e.g., stone fish ) employ ...
A latrotoxin is a high-molecular mass neurotoxin found in the venom of spiders of the genus Latrodectus (widow spiders) as well as at least one species of another genus in the same family, Steatoda nobilis. [1] Latrotoxins are the main active components of the venom and are responsible for the symptoms of latrodectism.
