ABSTRACT
An outbreak of nervous disease in Standardbred horses occurred near Bendigo, in south-eastern Australia, in October 1980. Over a two week period 11 horses in four training stables were affected with gait abnormalities, depression and recumbency. Eight of the 11 died. The results of an investigation implicated Clostridium botulinum toxin as the cause. The toxin was food-borne as a contaminant of oaten chaff.

Porcine enteroviruses were isolated from weaner pigs that had nervous signs and mild non-suppurative meningoencephalomyelitis and ganglioneuritis. The clinical signs and lesions were not typical of enterovirus infection and it is believed that an organic arsenical present in feed enhanced pathogenicity of enteroviruses. Severe non-suppurative polioencephalomyelitis and ganglioneuritis were produced in gnotobiotic pigs by oral inoculation of the viruses.
