Botulism is a rare but potentially fatal syndrome of diffuse, flaccid paralysis caused by botulinum neurotoxin (BoNT), a neurotoxin elaborated by the bacterium and 6 other clostridial genospecies. Several other etiologies of botulism have been described since its recognition as a foodborne entity in Germany and Belgium in the 1800s, including wound botulism, iatrogenic botulism, and inhalational botulism. The administration of polyvalent antitoxin to BoNT mitigates the clinical course of botulism. However, no true antidote exists, and disease management relies on potentially weeks of mechanical ventilation and other resource-heavy therapies while the body's neuromuscular signaling mechanisms recover. BoNT, the most potent poison known to man, is relatively simple to produce, store, and disperse. Thus, this toxin is a subject of intense interest for defense organizations worldwide. Due to its toxicity, BoNT has been previously implicated in biological warfare and bioterrorism plans with state-based actors and terror groups such as the Red Army Faction and Aum Shinrikyo in the 1980s and 1990s. Despite this, BoNT can be managed in accredited biosafety level 2 containment facilities as it is not transmissible following initial exposure.
肉毒中毒是一种罕见但可能致命的弥漫性、弛缓性麻痹综合征,由肉毒杆菌神经毒素(BoNT)引起,BoNT是一种由肉毒杆菌及其他6种梭菌属菌种产生的神经毒素。自19世纪在德国和比利时被确认为食源性疾病以来,人们又描述了肉毒中毒的其他几种病因,包括创伤性肉毒中毒、医源性肉毒中毒和吸入性肉毒中毒。给予抗BoNT多价抗毒素可减轻肉毒中毒的临床病程。然而,目前尚无真正的解毒剂,疾病管理依赖于可能长达数周的机械通气和其他资源密集型治疗,直到身体的神经肌肉信号传导机制恢复。BoNT是人类已知的最剧毒物质,其生产、储存和传播相对简单。因此,这种毒素是全球国防组织密切关注的对象。由于其毒性,BoNT此前曾被卷入20世纪80年代和90年代一些国家行为体和恐怖组织(如红军派和奥姆真理教)的生物战和生物恐怖主义计划中。尽管如此,BoNT可以在达到生物安全2级标准的防护设施中进行处理,因为初次接触后它不会传播。
