a relationship between avian carcasses and living invertebrates in the epizootiology of avian botulism.a survey of the sources of clostridium botulinum type c toxin possibly utilized as food by aquatic birds in an epizootic area of avian botulism in northern utah showed that living aquatic and terrestrial invertebrates normally found in close association with dead, decomposing birds commonly carried the toxin. of 461 samples associated with 21 species of avian carcasses, 198 were toxin-positive. invertebrate species not normally scavengers of vertebrate tissues were less commonly and less highly ...19761255907
