Four forms of salmonellosis were recognised in feedlots and during transport by sea: septicaemic, and acute, subacute and chronic enteric. The severity and distribution of lesions in the enteric forms varied according to the progression of the pathological process. The acute disease involved the abomasum and small intestine whereas the subacute disease centred on the lower small intestine and upper intestine. Chronic disease involved considerable mucosal repair in the ileum, caecum and proximal colon. Septicaemic salmonellosis was often accompanied by acute enteritis and occasionally by cholecystitis. S typhimurium was the most frequently encountered serotype.
