Thirty-four Holstein cows died after exposure to Clostridium botulinum type D toxin, presumably from contaminated haylage. The presence of type D toxin in ruminal contents was confirmed by mouse inoculation. This is the first confirmation by direct toxin isolation of C. botulinum type D toxin in cattle in North America.
34头荷斯坦奶牛在接触D型肉毒梭菌毒素后死亡,推测是由于食用了受污染的青贮干草。通过小鼠接种证实瘤胃内容物中存在D型毒素。这是北美首次通过直接毒素分离法证实牛体内存在D型肉毒梭菌毒素。
