The pathophysiology of a spider bite is due to the effect of its venom. 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. Some spider bites do leave a large enough wound that infection may be a concern. However, it is generally the toxicity of spider venom that poses the most risk to human beings; several spiders are ...
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. Most bites result in mild symptoms around the area of the bite. Rarely they may produce a necrotic skin wound or severe pain. Most spiders do not cause bites that are of importance. For a bite to be significant, substantial envenomation is required. Bites from the widow spiders involve a neurotoxic venom which produces a condition known as latrodectism. Symptoms may include: pain which may be at the bite or involve the chest and abdomen, sweating, muscle cramps and vomiting among others. ...
... is the illness caused by the bite of Latrodectus spiders (the black widow spider and related species). Pain, muscle rigidity, vomiting, and sweating are the symptoms of latrodectism. Contrary to popular conception, latrodectism is very rarely fatal to people though domestic cats have been known to die with convulsion and paralysis. There are several spider species all named black widow: southern black widow spider (L. mactans), the European black widow (L. tredecimguttatus), Western black widow spider (L. hesperus), Northern black widow spider (L. variolus). Other Latrodectus that cause latrodectism are the Australian redback spider (L. hasselti), and the New Zealand katipo spider (L. katipo). Several other members of ...
Treatment is based on the severity of poisoning from the bite; the majority of cases do not require medical care, and patients with localised pain, swelling and redness usually only require local application of ice and simple oral analgesia such as paracetamol. Pressure immobilisation of the wound site is not recommended. Keeping the victim still and calm is beneficial.[57][126] Hospital assessment is recommended if simple pain relief does not resolve local pain, or systemic symptoms occur.[127][128] Opioid analgesics may be necessary to relieve pain.[102] Antivenom has been historically given for adults suffering severe local pain or systemic symptoms consistent with latrodectism, which include pain and swelling spreading proximally from site, distressing local or systemic pain, chest pain, abdominal pain, or excessive sweating (diaphoresis).[129] A significant proportion of bites will not result in envenomation or any symptoms developing; around 2-20% of ...
People who have been bitten by a black widow spider are recommended to seek professional medical assistance for symptoms.[16] Symptoms self-resolve in hours to days in a majority of bites without medical intervention.. Medical treatments have varied over the years. Some treatments (e.g. calcium gluconate) have been discovered to be useless.[17] Currently, treatment usually involves symptomatic therapy with pain medication, muscle relaxants, and antivenom. When the pain becomes unbearable, antivenom is administered. Antivenom historically completely resolves pain in a short time.[4][18] Antivenom is made by injecting horses with latrodectus venom over a period of time. The horse develops antibodies against the venom. The horse is bled and the antibodies purified for later use. Doctors recommend the use of anti-inflammatory medications before antivenom administration, because antivenom can induce allergic reactions to the ...
... (EC 3.1.4.41, sphingomyelinase D) is an enzyme of the sphingomyelin phosphodiesterase family with systematic name sphingomyelin ceramide-phosphohydrolase. These enzymes catalyse the hydrolysis of sphingomyelin, resulting in the formation of ceramide 1-phosphate and choline: sphingomyelin + H2O ⇌ {\displaystyle \rightleftharpoons } ceramide 1-phosphate + choline or the hydrolysis of 2-lysophosphatidylcholine to give choline and 2-lysophosphatidate. Sphingomyelin phosphodiesterase D activity is shared by enzymes with a wider substrate range, classified as phospholipases D or lipophosphodiesterase II EC 3.1.4.4. Sphingomyelinases D are produced by some spiders in their venoms, by arthropods such as ticks, or pathogenic bacteria and fungi. Pathogenicity is expressed through different mechanisms, such as membrane destabilization, cell penetration, inflammation of the lungs and cutaneous lesions, common following spider ...
... , the red-backed jumping spider, is one of the largest and most commonly encountered jumping spiders of western North America. It is not to be confused with the unrelated and highly venomous redback spider (Latrodectus hasselti). Adults tend to be about a centimeter in length. Both sexes have a bright red abdomen; the female has in addition a black central stripe. The chelicerae of both sexes are of a shining teal color. The rest of the body is mostly black. It is one of the species of jumping spiders that are mimics of mutillid wasps in the genus Dasymutilla (commonly known as "velvet ants"); several species of these wasps are similar in size and coloration, and possess a very painful sting. The distribution of P. johnsoni is bounded by the Great Plains, the Pacific Ocean, northern Mexico and southern Canada. It occurs from sea level to tree line, occupying relatively ...
At one stage the oldest fossil spider was believed to be Attercopus which lived 380 million years ago during the Devonian. Attercopus was placed as the sister-taxon to all living spiders, but has now been reinterpreted as a member of a separate, extinct order Uraraneida which could produce silk, but did not have true spinnerets. The oldest true spiders are thus Carboniferous in age, or about 300 million years. Most of these early segmented fossil spiders from the Coal Measures of Europe and North America probably belonged to the Mesothelae, or something very similar, a group of primitive spiders with the spinnerets placed underneath the middle of the abdomen, rather than at the end as in modern spiders. They were probably ground-dwelling predators, living in the giant clubmoss and fern forests of the ...
... (1908) is a supernatural horror novel by British fantasist William Hope Hodgson. The novel is a hallucinatory account of a recluse's stay at a remote house, and his experiences of supernatural creatures and otherworldly dimensions. American horror writer H. P. Lovecraft listed The House on the Borderland and other works by Hodgson among his greatest influences, and Terry Pratchett has called the novel "the Big Bang in my private universe as a science fiction and fantasy reader and, later, writer". On the third day of their fishing holiday to the remote Irish village of Kraighten, Tonnison and Berreggnog stumble upon the ruins of a strangely shaped house on a large lake. They discover the mouldering journal of the Recluse, an unidentified man who recorded his last days in the house before its destruction. The Recluse begins his journal with descriptions of how he acquired the house, along with his daily life with his sister and his faithful dog, Pepper. ...
... s act by binding to and neutralizing venoms. The principle of antivenom is based on that of vaccines, developed by Edward Jenner; however, instead of inducing immunity in the person directly, it is induced in a host animal and the hyperimmunized serum is transfused into the person.[17] The host animals may include horses, donkeys, goats, sheep, opossums, rabbits, chickens, llamas, and camels.[citation needed] Antivenoms for medical use are often preserved as freeze-dried ampoules, but some are available only in liquid form and must be kept refrigerated. They are not immediately inactivated by heat, however, so a minor gap in the cold chain is not disastrous. Some ophiophagic animals produce natural antidotes that render them immune to certain snake venoms. No human is immune to animal venom, but some individuals may be more or less susceptible to its effects.[18]. A person can build up immunity to a particular venom through frequent low and increasing doses (about every 21 days), but ...
The bites of fleas, spiders, mosquito and bed bugs causes similar symptoms but there are a few differences that may help you find out the true cause.. Bed bug's bites mainly show up in groups or line formations due to the bed bug's nature to feed more than once in the same area. They appear on body parts that are exposed during the sleep, like hands, feet, neck. Those bites cause intense itching for a few days after appearing.. Flea's bites are smaller and more pinkish, the ones caused by spiders are mostly big, isolated single bites revealing pierced skin. Mosquitoes' bites are more pale and the itching gradually disappear after few hours.. There are herbal and chemical ways of removing Bed Bugs bites.[2]. ...
The legs of orb-weaver spiders are specialized for spinning orb webs. The webs are built by the larger females who hang head down in the center of the web or remain hidden in nearby foliage, with one claw hooked to a signal line connected to the main orb waiting for a disturbance to signal the arrival of prey. Prey is then quickly bitten and wrapped in silk before being stored for later consumption. The initial bite serves to paralyze the prey and minimize the danger of the spider herself being stung or bitten, and the enzymes thus injected serve to begin liquefaction of the prey's internal structures. Alongside the use of the web to capture other prey, the spiders are also cannibals and prey on each other. However, this only happens before or after sexual activity. They attack based on their size, sexual experience and hunger levels. A. diadematus is a ...
Spiders generally use elaborate courtship rituals to prevent the large females from eating the small males before fertilization, except where the male is so much smaller that he is not worth eating. In some species males mate with newly molted females, which are too weak to be dangerous to the males.[4] In web-weaving species precise patterns of vibrations in the web are a major part of the rituals, while patterns of touches on the female's body are important in many spiders that hunt actively, and may 'hypnotize' the female. Gestures and dances by the male are important for jumping spiders, which have excellent eyesight. If courtship is successful, the male injects his sperm from the pedipalps into the female's genital opening on the underside of her abdomen. Female reproductive tracts vary. Some are simple tubes, but others have chambers where females store sperm, and release it when they are ready.[5] ...
