Loxoscelism (/ l ɒ k ˈ s ɒ s ɪ l ɪ z əm /) is a condition occasionally produced by the bite of the recluse spiders (genus Loxosceles). The area becomes dusky and a shallow open sore forms as the skin around the bite dies . It is the only proven type of necrotic arachnidism in humans.
The Australian red-back and North American widow species live near humans and bites are frequent, numbering thousands yearly. The venom produces very painful effects including muscle spasms, 'tetanus-like' contractions, nausea and vomiting, and severe generalized pain. A serious bite will often require a short hospital stay to control pain.
Symptoms of a bite depend on the amount of venom injected. A bite of Latrodectus may not inject any venom (known as a dry bite) and so no illness occurs. About 75% of "wet" bites will have localized pain and nothing more. [1] If, however, there is a substantial dose, a bite can cause latrodectism.
Tetramorium uelense is a specialised predator species that feeds on small termites. A scout recruits 10–30 workers to an area where termites are present, killing them by immobilising them with their stinger. [151] Centromyrmex and Iridomyrmex colonies sometimes nest in termite mounds, and so the termites are preyed on by these ants. No ...
Spiders do not feed on humans and typically bites occur as a defense mechanism. [20] This can occur from unintentional contact or trapping of the spider. [20] Most spiders have fangs too small to penetrate human skin. [21] Most bites by species large enough for their bites to be noticeable will have no serious medical consequences. [22]
Erethism, [n 1] also known as erethismus mercurialis, mad hatter disease, or mad hatter syndrome, is a neurological disorder which affects the whole central nervous system, as well as a symptom complex, derived from mercury poisoning.
A bite is defined as coming from the mouthparts of the arthropod. The bite consists of both the bite wound and the saliva. The saliva of the arthropod may contain anticoagulants, as in insects and arachnids which feed from blood. Feeding bites may also contain anaesthetic, to prevent the bite from being felt.
A centipede bite is an injury resulting from the action of a centipede's forcipules, stinger-like appendages that pierce the skin and inject venom into the wound. Such a wound is not strictly speaking a bite , as the forcipules are a modified first pair of legs rather than true mouthparts .
