===Pigs===

Pigs are relatively resistant to anthrax. The disease in pigs has two manifestations- the pharyngeal and intestinal forms.  The pharyngeal disease is linked with scavenging or purposeful feeding of infected carcasses and often begins as an oedematous cellulitis of the the neck, head and regional lymph nodes. This may cause death by asphyxia. The intestinal form is thought to be associated with contaminated mineral supplements, and may produce less obvious clinical signs including diarrhoea, lethargy and anorexia.

Animals affected by the intestinal form frequently recover.
