水禽肉毒中毒是中毒中的独特之处,因为其受害者体内产生的毒素会导致其他鸟类的二次中毒。由于这种现象,肉毒中毒的尸体-蛆循环的动物流行病学类似于传染病,并且疾病的繁殖率(R)可以定义为可归因于引入沼泽的单个尸体的继发中毒的平均数量。我建议,毒素的生产和肉毒杆菌中毒通常发生在一个低水平,在许多沼泽和影响R的因素,决定当疾病扩大到一个大的动物流行病。一个模型,结合尸体的数量发生在沼泽,尸体的概率包含孢子,尸体持续到带毒素的蛆出现的概率,和活禽和毒素之间的接触率,可能是有用的预测二次中毒的程度,为确定研究的问题,并作为管理的理论基础。
Waterfowl botulism is unique among intoxications because toxin produced within its victims leads to secondary poisoning of other birds. Because of this phenomenon, the epizootiology of the carcass-maggot cycle of botulism resembles that of an infectious disease and the reproductive rate (R) of the disease could be defined as the average number of secondary intoxications attributable to a single carcass introduced into a marsh. I propose that toxin production and botulism occur commonly at a low level in many marshes and that factors which influence R determine when the disease expands into a large epizootic. A model that incorporates the number of carcasses occurring in a marsh, the probability of a carcass containing spores, the probability of a carcass persisting until toxin-bearing maggots emerge, and the contact rate between live birds and toxin, may be useful for predicting the extent of secondary-poisoning, for identifying questions for research, and as a theoretical basis for management.
