There's no spider or venom that directly causes that though.

It's a myth that white-tailed spiders do this and has been debunked.

More likely the spider bite or some other injury was an entry point for bacteria found in the soil.

Yabbies are awesome, tasty little suckers and so easy to catch.

Feel like eating some now actually.

Some moron did a study and you automatically believe it regardless of all the actual accounts of white tailed spider bites? Huh, i suppose you also believe the experts who insist chocolate never causes pimples? hahahaha

Its sweet that you are so trusting :)

As for yabbies... i cannot believe i used to shove my bare hand down their holes and pull them out.... man i was a crazy kid.... could never be so brave today!

Professors and experts have found no evidence of it, I wouldn't call them morons.

The only "evidence" is anecdotal, hardly convincing.

And another reason is that the white-tailed spider bite is painful, it was reported that this poor guy didn't feel anything.

EDIT: "A debate continues about the involvement of White-tailed Spider bite in cases of severe ulcerative skin lesions seen in patients diagnosed as probable spider bite victims. Typically, in such cases no direct evidence of spider bite is available. Sensational media reporting of supposed cases of severe "necrotising arachnidism" has given the White-tailed Spider a bad reputation. However, a recent study has monitored the medical outcomes of over 100 verified White-tailed Spider bites and found not a single case of ulceration (confirming the results of an earlier study). The available evidence suggests that skin ulceration is not a common outcome of White-tailed Spider bite."

Could you send me via mail, some spiders like those, please? By the way, are they small enough and hard to notice, or do they stand out? I am very sorry for the poor dog, though...

Thanks.

I was walking him when it happened, let him off the leash to run around and a minute later he dropped like a fly.

His tongue was blue, eyes rolled back, drooling and panting heavily and broke out in hives.

I felt so helpless as I didn't know what it was at the time, not that I could have done anything if I did.

Had to leave him there and run back home to get the car, was crying like a baby all the way home.

Now I carry an Epipen; they cost $100 here and expire every year, so this will be an ongoing cost but I'm not taking any chances.

Frustrating thing is I have no idea what bug caused it.

Get yourself some Brazilian Wandering Spiders, they are seriously nasty.

Well my advice to you is that these experts are fxxxwits every one of them..... better to assume these white tailed spiders are very dangerous, for your own safety.

Evolution has obviously taken white tailed spider bites down a different road than pure venom.... possibly something similar to Komodo Dragon bites or something entirely new. but one thing i can promise you is that these experts are fxxxwits.

The spider isn't what caused the damage, and you'd know if it you read some more. The poison from that spider isn't the problem, in fact, it's not even poisonous to humans. Either necrotising arachnidism, or necrotising fasciitis causing bacteria that took advantage of the wound was the main culprit.

Since the White-tailed spider hasn't been definitively proven to cause necrotising arachnidism, the doctor even suggests that it was caused by a bacteria passed through the wound.

edit: wow, I started writing this a few posts ago...
You'd be surprised what an opportunistic pathogen can do. Better to assume that deadly bacteria is anywhere, in any part of the world. Source: budding expert knowledge ;)
Here's a brief summary on Group A Streptococcus: http://nanologix.com/bacteria/group_a_strep.html

No.... more like the bite of the Komodo Dragon.... the animal is 'using' the pathogens, not just some random pathogen event.

Its amazing how often overwhelming 'anecdotal' knowledge once said to be wrong by science, is then proven to be correct later on with further scientific progress. You will see this happen with White tailed spiders eventually

No... more like the bite of a Brown Recluse.
The Komodo Dragon (or other monitor variants) don't harbour some pathogen! WTF mate? They have venomous proteins.
edit: Venom producing glands, to be precise. You're working off a MYTH, that has been proven a myth.

No, read it properly, its a combination of venom and pathogens, which is the hunting strategy of the animal.

Obviously the animal has to have something to boost the speed of the bacteria otherwise it is no different to any other animal.... same as the white tailed spider. They have evolved their venom to enhance bacteria, either directly or indirectly by weakening defenses is my guess.

Edit: in the case of the white tailed spider it is a defense
in the case of the Komodo Dragon it is their hunting strategy.

stubborn as a mule. We'll leave it there big guy.

No problem... then in 5/10 years time when they discover more, remember this thread :)

We don't allow foreigners to engage in sexual acts with our prostitutes, they're ours.

Here in Australia we take great pride in our ability to find ways of making things more expensive than the need to be!
