Salmonellosis in young calves due to Salmonella enteritidis

The clinical and epidemiological features of an outbreak of salmonellosis due to Salmonella enteritidis in a group of calves are described. The major clinical signs were dullness, pyrexia and diarrhoea. Five of the 15 calves died but deaths were mainly confined to the younger members of the group. The recovery of salmonella organisms from rectal swabs was maximal shortly before four of the five deaths occurred and declined rapidly thereafter. Only two of the surviving 10 calves developed significant flagellar agglutination titres.
