[8][9] Local daycares, preschools and schools arrange daytrips here and parents are forewarned about the risk by required consent forms, although only one bite has ever been recorded. Systemic corticosteroids are often considered, but without clinical trials to support the practice. The damaged tissue will become gangrenous black and eventually slough away. According to one study, the venom of the Chilean recluse along with the six-eyed sand spider Hexophthalma hahni, contains an order of magnitude more of this substance than that of other sicariid spiders such as the brown recluse. generally undisturbed. Es una de las especies de Loxosceles de mayor tamaño (hasta 15 mm) y más ancha (o robusta) que sus … The spider is frequently found in human dwellings. El veneno que produce Loxosceles laeta pudiera ser mortal para el hombre, dependiendo de la relación entre la cantidad inoculada y masa del individuo. The spiders can last a long time without food or water,[3] a fact that encourages their worldwide spread. Bites are felt initially but may take up to seven hours to cause visible damage; more serious systemic effects may occur before this time, as venom of any kind spreads throughout the body in minutes. Las investigaciones señalan que puede ser hasta 15 veces más tóxico … Materials and methods 2.1. One colony of the spider is living in the Natural History Museum of Helsinki where it was probably introduced through fruit shipments in the 1960s and 1970s. Initially there may be no pain from a bite, but over time the wound may grow to as large as 10 inches (25 cm) in extreme cases. Since the "violin pattern" is not diagnostic, it is far more important, for purposes of identification, to examine the eyes. All animals received water and food ad libitum. Loxosceles laeta: características, habitat, nutrição, reprodução. [19] Retrospective data are limited because they lack a definition of time to antivenom administration and its relation to outcome. No controlled trials have been reported; the practice is controversial, but clinical experience in Perú and several limited studies support this practice. Esta sustancia letal está compuesta por poderosas enzimas que destruyen todo aquello que tenga proteínas. [18] Applying aloe vera may soothe and help control the pain. Ha sido introducida accidentalmente en diferentes países de América del Norte y América Central, así como también en Australia, Finlandia y España. The Chilean recluse spider is a highly venomous spider, Loxosceles laeta, of the family Sicariidae (formerly of the family Loxoscelidae). Es originaria de América del Sur, común en Chile, Perú, Ecuador, Argentina, Uruguay, Paraguay y Brasil. Loxosceles laeta can produce 60 µg of venom by electrostimulation, compared to 30-40 µg of Loxosceles intermedia and Loxosceles gaucho. Pertence ao gênero Loxosceles, sendo a maior espécie desse grupo. [citation needed] The spider is known to have established itself in the Los Angeles area. Like all sicariid spiders, the venom of the Chilean recluse contains the dermonecrotic agent Sphingomyelinase D, which is otherwise found only in a few pathogenic bacteria. Animals, venoms and antivenoms Adult male Swiss mice (weighing 18–22 g) were main-tained at the Centro de Bioterismo of the Instituto de Ciências Biológicas of the Universidade Federal de Minas Gerais (UFMG), Belo Horizonte, MG, Brazil. The recluse spiders (Loxosceles (/ l ɒ k ˈ s ɒ s ɪ l iː z /), also known as brown spiders, fiddle-backs, violin spiders, and reapers, is a genus of spiders that was first described by R. T. Lowe in 1832. It is common in Chile, and can be found in Perú, Ecuador, Argentina, Uruguay, and south and eastern Brazil.[4][5]. Su acción es necrótica y proteolítica, ya que disuelve los tejidos corporales, causando la muerte celular. Like most recluses, it is brown and usually has markings on the dorsal side of its thorax, with a black line coming from it that looks like a violin with the neck of the violin pointing to the rear of the spider resulting in the nickname "fiddleback spider" or "violin spider" in English-speaking areas. In South America, dapsone has been tried at 100 mg/day for one week, unless there is active hemolysis or G6PD deficiency. [15][16] In Peru, the mortality rate was 18% for those over 13 years old, and 50% for children under 13 years old.[17]. [13] In Peru, viscerocutaneous loxoscelism occurs in 27.2% of cases, in Chile it occurs in 15.7% and in the state of Santa Catarina, in Brazil it occurs in 13.1%. Viscerocutaneous loxoscelism manifests with skin blanching due to vasoconstriction, sometimes a dengue-like scarlatiniform rash, hemolysis, sometimes resulting in hemoglobinuria, hemolytic anemia and acute tubular necrosis leading to kidney failure, and death in 3%–4% of cases per a study covering 30 years of bites in Chile. Loxosceles laeta often produces extensive webbing that is particularly noticeable in corners of rooms and along floor-level runways that they follow at the base of walls. The Chilean recluse spider is a highly venomous spider, Loxosceles laeta, of the family Sicariidae (formerly of the family Loxoscelidae). The spider should be brought with the patient in a clear, tightly closed container for identification, if it can be captured. 648 0 obj <> endobj 676 0 obj <>/Filter/FlateDecode/ID[<6054CC6611C6F8BF8D698DBB52D5C1E5>]/Index[648 135]/Info 647 0 R/Length 133/Prev 987133/Root 649 0 R/Size 783/Type/XRef/W[1 3 1]>>stream Application of an ice pack helps as first aid, because the venom is more active at high temperatures.
