Phoneutria nigriventer - Wikipedi

  1. Phoneutria nigriventer is a species of medically significant spider in the family Ctenidae, found in South America (Brazil, Uruguay, Paraguay, and Argentina). Along with other members of the genus, they are often referred to as Brazilian wandering spiders
  2. Phoneutria nigriventer venom (PNV) is a complex mixture of toxins exerting multiple pharmacological effects that ultimately result in severe local pain at the site of the bite. It has been proposed that the PNV-induced pain is mediated by both peripheral and central mechanisms
  3. The venom of Phoneutria nigriventer has been studied for over 60 years. This spider is responsible for a high number of envenomations with severe clinical manifestations in humans, which necessitates a comprehensive knowledge of its venom composition
  4. Several spider toxins have been identified biochemically and some of them are specific glutamate receptors antagonists. Previous data indicate that PnTx4-5-5, a toxin isolated from the spider Phoneutria nigriventer, inhibits the N-methyl-d-aspartate receptor (NMDAR), with little or no effect on AMPA, kainate or GABA receptors

  7. Other results clearly confirmed that venoms of three compared Phoneutria species show qualitative and quantitative differences, despite an overall similarity in components. The most obvious difference is between venom of P. nigriventer (the synantropic species) and P. reidy. Venom of the latter species contains a much higher concentration of the components strongly acting on insects rather than on mammals (mice)

The Phoneutria nigriventer spider toxin, PnTx4-5-5

Common name i. Brazilian armed spider. Synonym i. Ctenus nigriventer. Other names i. ›Phoneutria nigriventer (Keyserling, 1891) Rank i. SPECIES. Lineage i Abstract. The venom of Phoneutria nigriventer spider has been extensively studied. It is highly neurotoxic, with clinical manifestations occurring a few minutes after the bite, mainly in children. Among the intoxication signs that may lead to neurogenic shock are agitation, somnolence, sweating, nausea, profuse vomiting, lacrimation, excessive salivation, hypertension, tachycardia, tachypnea. Phoneutria nigriventer is one of the largest existing true spiders and one of the few considered medically relevant. Its venom contains several neurotoxic peptides that act on different ion channels and chemical receptors of vertebrates and invertebrates. Some of these venom toxins have been shown as promising models for pharmaceutical or biotechnological use Putting aside toxicity comparisons, Phoneutria is extremely fast and yes, can jump. Atrax has very powerful fangs that can pierce, but is not one to leaping. It relies on a downward thrust, and often does not penetrate if not at the precise angle. Phoneutria also has the world's largest venom glands

Phoneutria nigriventer venom is studied for containing low molecular weight non-protein compounds and approximately 41 neurotoxins with the potential capacity to cross the blood-brain barrier [1,2,3]. PhTx3 is the most studied fraction; six toxins have been characterized and their peptides act on voltage-dependent calcium (Ca V) channels Toxicon29, 1225-1233, 1991.—Three neurotoxic fractions, lethal to mice, were isolated from the venom of the spider Phoneutria nigriventer, by gel filtration and reverse phase chromatography.

Ang Phoneutria nigriventer sakop sa kahenera nga Phoneutria sa kabanay nga Ctenidae. Pagka karon wala pay siak nga nalista ubos niini niya Phoneutria és un gènere d'aranyes araneomorfes de la família dels ctènids (Ctenidae). Fou descrita per primera vegada per M. Perty l'any 1833. Les aranyes d'aquest gènere són sobrenomenades aranya bananera, perquè són conegudes per amagar-se també en plantacions de bananes.La seva distribució es localitza a Amèrica del Sud, amb alguna espècie també a Amèrica Central Araña del banano (Phoneutria nigriventer) en su característica postura defensiva. No es la que encontraron hoy en Montevideo (que publicamos hace unos minutos), es la que encontraron hace unos días..
