Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

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

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

Hufanya nini akiogopa?

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

Akiuma

Osha jeraha na uweke barafu kupunguza maumivu. Tafuta msaada wa kitabibu kama maumivu ni makali, yanasambaa au mtu anajisikia vibaya.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

It produces about 5.6 mg of venom, and the male produces less, around 2.43 mg.1

Males have much longer legs than females, although the female has the larger body.1

Its webs are irregular and built under fallen tree trunks and debris, usually in dark places.1
