The guinea pig died within 7 minutes, leading to a belief that the spider's venom was dangerous. However, further research on anaesthetized guinea pigs showed that the original guinea pig had actually died of shock, rather than as a result of the spider's venom. [1] In humans the bite is no more dangerous than a bee sting. [4]
Palystes is a genus of huntsman spiders, commonly called rain spiders or lizard-eating spiders, [2] occurring in Africa, India, Australia, and the Pacific. [1] The most common and widespread species is P. superciliosus , found in South Africa, home to 12 species in the genus.
Araneus gemmoides, commonly known as the jewel spider (a name shared with Austracantha minax) and cat-faced spider (a name shared with Araneus gemma), is a common, outdoor, orb-weaver spider found in Canada and the USA. [1] It is considered harmless and has a low-toxicity venom. [2] A. gemmoides is a useful natural predator for insects. [1] [3] [4]

However, most bite victims suffer only local pain and bleeding, a few more have limited neurotoxic symptoms (tingling, racing heart, more widespread pain), and there have been several recorded bites by this spider producing severe symptoms requiring medical treatment. [37] There are no recorded human fatalities due to mouse spider bites.
The symptoms of a bite are typically similar to a bee or wasp sting. However, the bite of Steatoda nobilis, along with others in its genus, can also produce a set of symptoms known as steatodism. [12] These symptoms include intense pain radiating from the bite site, along with feverishness or general malaise. [33]
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 ...
