The Brazilian brown recluse spider is a small spider that is highly venomous. It lives in parts of Brazil and Argentina, and it is one of the species linked to deaths from spider bites in South America. Its bite can seem mild at first, so it matters to know what it looks like.1

Moč strupa

Ugrizi

Strup pride ven skozi strupnike ali zobe, ko ugrizne.

Kaj naredi njen strup, ko ugrizne ali piči?

Its venom contains a high concentration of the enzyme sphingomyelinase D, which causes both local and whole-body effects. Symptoms usually take hours to appear. The bite starts with severe pain, redness, swelling and blisters, and in more severe cases the skin tissue can die. Whole-body effects can include damage to red blood cells, heart problems, low blood pressure, kidney failure and severe bleeding.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: ResnoPo ugrizu je potreben zdravnik. Smrtni primeri so zelo redki.

It is one of the main species linked to deaths from spider bites in South America. Whole-body effects occur frequently after its bite. Because symptoms are delayed, a victim may think the bite was mild.1

Kaj naredi, ko se prestraši?

It is a very shy spider that keeps to dark places, so it is rarely seen.1

Če ugrizne

  • Ugriz umij in nanj daj ledeni obkladek proti bolečini. Poišči zdravniško pomoč, če je bolečina močna, se širi ali se poškodovanec slabo počuti.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

  • Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
  • Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
  • Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti
