Hi Venom,Originally posted by Venom
How would you rate Loxosceles leata, which has a very high incidence of systemic affects ( viscerocutaneus loxoscelism ), from which deaths are not too uncommon, taking into account its size, aggression, and its abundance in populated areas?
Is this where you sourced your info? I still don't believe there is one single confirmed fatality from any Loxocseles sp. Any other info to back up the fatality thing? The site on the wanderer is interesting, considering not one single spider is "poisonous". Most are venomous, but not poisonous as the site wrongly suggests.Originally posted by Venom
Actually, there have been deaths from L. leata, and what I meant by "systemic loxoscelism" was the affects of the bite other than local necrosis. Loxosceles venom has in fact been analyzed as containing several enzymes that cause the necrosis. You should visit these websites:
Good luck From what I can ascertain, most paperwork on the recluses mentions deaths involved, but not one report is substantiated. If you can find one confirmed death, I know of at least two pro taxonomists who'll want to know.Originally posted by Venom
>>I'll see if I can find some reliable death stats on Loxosceles.
And that's why I wouldn't hold any weight to that sites info....It could be called petty, but when dealing with such medical issues the correct terminology is fairly important, no? And if that can be overlooked how correct is their info going to be?>> ( I think they meant "venomous", but used the term "poisonous" because they didn't know the different there was a difference.)
The work was carried out by a few more people then Raven, although he was involved. The study wasn't just on L.cylindrata but coverd the families Clubionidae, Miturgidae,Gnaphosidae, Lycosidae and Salticidae. All members of these families were capable of causing necrotic arachnidism in humans. I KNOW the results for all these families showed that bacteria caused the necrosis, and it was hypothesized that the bacteria came from a particular prey item. Because these spiders are all rovers it's believed the prey item is a ground crawler (no web spinners can cause necrosis). What I will find out is if the family Loxoscelidae was also involved in the study.You'd think whoever analyzed the venom could tell the difference between bacterial enzymes, and arachnid venom. Are you sure you're not thinking about the white-tailed spider ( Lampona sp. )? I read that it's necroses were possibly bacterial in origin- again, from bacteria on the spiders' chelicera. Did you get Loxosceles and Lampona mixed up, or were the analyses of Dr. Raven actually for the recluse spiders?

You haven't heard the stories of the Drop Bears, have you??Originally posted by belewfripp
If someone told me that, in truth, koala bears carry sniper rifles and enjoy picking off tourists from a distance, i don't think it'd surprise me in the least.
