Presumptive diagnosis of Clostridium botulinum type D intoxication in a herd of feedlot cattle.

摘要

Fifty-two feedlot cattle exhibited clinical signs suggestive of botulism. Clostridium botulinum type D organisms were recovered from ruminal fluid of 4 of the 5 affected animals tested and were isolated from bakery waste fed to the cattle. Clostridium botulinum type D has not been reported previously in Canadian cattle.
