Tegenaria agrestis
is common species in Eurasia and an import in the United States.
In the 1980s,
Darwin Vest, doing a considerable amount of detective work, built a case
against this species suggesting that it was responsible for many suspected
spider bites resulting in imflammations, lesions and other.
So far, this
accusation has not been confirmed. A good animal model for identifying a
necrotic has not been found. The venom does not contain a sphingomyelinase
similar Loxosceles necrotoxin (though a necrotic toxin could be created by
something else) and the venom of imported T. agrestis appear to be similar
to European spiders, which are not suspect. In addition, we do not have
clinical reports in which the bite was witnessed and the spider was properly
identified. |
