The Australian scrub-tick Ixodes holocyclus causes a series of significant toxic effects in its victims. The most important feature of tick envenomation is neuromuscular paralysis. Children poisoned by ticks may manifest only local motoneural effects, usually facial paralysis. Progressive ascending flaccid paralysis occurs if the removal of an embedded tick is delayed. The specific neurological features of tick-bite are discussed in the light of a series of 6 children who all showed signs of tick paralysis. Tick venom is known to slow nerve conduction, and may have a botulinum-like effect at the neuromuscular junction. The literature on the neurological effects of tick-envenomation is reviewed.
澳大利亚短角硬蜱全环硬蜱会对受害者造成一系列严重的毒性影响。蜱虫叮咬中毒最重要的特征是神经肌肉麻痹。被蜱虫叮咬中毒的儿童可能仅表现出局部运动神经效应，通常为面部麻痹。如果延迟拔除嵌入的蜱虫，会出现进行性上升性弛缓性麻痹。根据6名均表现出蜱虫麻痹症状的儿童病例，对蜱虫叮咬的具体神经学特征进行了讨论。已知蜱虫毒液会减缓神经传导，并且可能在神经肌肉接头处产生类似肉毒杆菌的作用。本文对蜱虫叮咬中毒的神经学影响相关文献进行了综述。
