Abstract

This study compiled 33 verified spider bites from the state of Oregon (USA). The initial goal was to amass a series of bites by the hobo spider to assess whether it possesses toxic venom, a supposition which is currently in a contested state. None of the 33 bites from several spider species developed significant medical symptoms nor did dermonecrosis occur. The most common biters were the yellow sac spider, Cheiracanthium mildei (N = 10) and orb-weavers of the genus Araneus (N = 6). There were 10 bites from three genera of funnel web spiders of the family Agelenidae including one hobo spider bite and one from the congeneric giant house spider which is readily confused as a hobo spider. The hobo spider bite resulted in pain, redness, twitching in the calf muscle and resolved in 12 h. Also generated from this study were possibly the first records of bites from spiders of the genera Callobius (Amaurobiidae) and Antrodiaetus (Antrodiaetidae), both with minor manifestations.

摘要

本研究收集了来自美国俄勒冈州的33例经证实的蜘蛛咬伤案例。最初的目标是积累一系列流浪汉蜘蛛的咬伤案例，以评估其是否拥有有毒毒液，目前这一假设仍存在争议。这33例由几种蜘蛛造成的咬伤均未出现明显的医学症状，也未发生皮肤坏死。最常见的叮咬蜘蛛是黄斑蛛（Cheiracanthium mildei，N = 10）和园蛛属（Araneus）的圆网蛛（N = 6）。有10例咬伤是由漏斗蛛科（Agelenidae）三个属的漏斗网蜘蛛造成的，其中包括1例流浪汉蜘蛛咬伤和1例易与流浪汉蜘蛛混淆的同属巨型家蛛咬伤。流浪汉蜘蛛咬伤导致疼痛、发红、小腿肌肉抽搐，12小时后症状缓解。该研究还可能首次记录了Callobius属（暗蛛科）和Antrodiaetus属（栉足蛛科）蜘蛛的咬伤案例，二者症状均较轻。
