The Brazilian Wandering Spider was recently found in some produce in a grocery store in Tulsa OK. It is considered the world's deadliest spider:
But, to add insult to injury:
WTF?????
(btw- here's the news story: http://news.yahoo.com/s/ap/200...on_re_us/deadly_spider)
venom contains a potent neurotoxin, known as PhTx3, which acts as a broad-spectrum calcium channel blocker that inhibits glutamate release, calcium uptake and also glutamate uptake in neural synapse. At deadly concentrations, this neurotoxin causes loss of muscle control, and breathing problems, resulting in paralysis and eventual asphyxiation. In addition, the venom causes intense pain and inflammation following an attack due to an excitatory effect the venom has on the serotonin 5-HT4 receptors of sensory nerves. This sensory nerve stimulation causes a release of neuropeptides such as substance P which triggers inflammation and pain.
But, to add insult to injury:
Aside from causing intense pain, the venom of the spider can also cause priapism - uncomfortable erections that can last for many hours and lead to impotence. The venom may eventually be used in erectile dysfunction treatments.
