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

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Byt moet deur 'n dokter gesien word. Sterftes is baie skaars.

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

Wat doen dit as dit bang is?

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

As dit byt

Was die byt en sit 'n yspak daarop vir die pyn. Kry mediese hulp as die pyn erg is, versprei of die persoon sleg voel.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly
