Biting back: Taking the sting out of spider venom

Brown recluse spiders bite more than 7,000 people in Brazil every year causing serious skin lesions and even death. The anti-venom used as treatment comes at the expense of many animal lives. But could a breakthrough in synthetic spider venom lead to a more humane solution?

"The first time I was bitten, I nearly died," says Adelaide Fabienski Maia, a school assistant from Curitiba.

"I put my shorts on in the morning and felt a bite but didn't realise what it was. It wasn't until the evening that my face started burning up. I looked at the bite area and it was red."

Adelaide was soon rushed to hospital with the classic target-shaped lesion caused by the venom eating away at her skin.

It was only thanks to a dose of anti-venom that she's still around to tell the tale.

But the anti-venom currently available comes with its own risks - mostly to the animals involved in the production process.

Venom is milked from thousands of brown spiders before being injected into horses. This triggers an immune response that creates life-saving anti-venom for humans - while drastically reducing the horses' own lifespan.

Now scientists in Brazil have come up with a synthetic venom alternative that could save many of those lives.

Brown Recluse Spider Bite: Nikki Perez Almost Blinded In Texas

A venomous brown recluse spider bite almost blinded a Texas woman and took part of her ear.
Nikki Perez, 21, documented the swelling of her face and the necrosis afflicting her ear over a two week period as the poison took hold, as (gruesome) pictures obtained by the Daily Mail show.
Perez was waiting at the Amarillo airport with her boyfriend Eric and his mom last September, when she felt a sharp sting on the back of her neck.
"Next, I felt something crawling over my face and my eye," she told the Daily Mail. "I yelled for Eric to help me, and when he saw the spider crawling over my face, he swatted it to the floor and stamped on it."
Her boyfriend's mom, a nurse, identified the all-telling mark on the brown recluse instantly: a violin-shaped mark on its back.
Doctors couldn't do much for Perez until she showed signs of necrosis, or dying skin cells. She took pictures of herself as her head began to swell -- so much so that her left eye swelled shut.
"I was going blind ... it was terrifying," she said. "It was spreading all over my head, which actually felt like a bit of a relief as the pain was so concentrated behind my ear."
When her ear started to literally rot off, she visited a spider expert and spent five days in the hospital, ABC News reported. Doctors surgically removed the dead tissue around her ear and injected her with steroids as her head started to shrink back to its normal size.
Perez made it out of the hospital with little more than a skin graft on her ear.
Other people bitten by the creature -- usually the elderly and children -- haven't been so lucky. The spider's poison can be lethal.
Worse, the recluse is reportedly spreading throughout North America as the planet warms. But the spiders are called "recluse" for a reason. The creepy arachnids rarely come out, and even when they do bite, they usually don't emit venom.
