SALMONELLA IN RUMINANTS, BOVINE, OVINE, CAPRINE SALMONELLOSIS
 
Description    The Gram-negative rod of the zoonotic genus SALMONELLA has one species called ENTERICA, 6 subspecies and over 2000 serotypes, some of which are host-adapted. Signs range from acute to chronic; shedders can carry the organism without signs. Bovine clinical Salmonellosis is most common in calves but can occur at any age. Septicemia, especially in young calves, causes sloughing of the skin of the extremities in rare cases and meningitis is sometimes part of the disease syndrome. Abortion can follow fetal infection. In sheep some serovars of the zoonotic bacterium SALMONELLA ENTERICA are associated primarily with abortion but others cause signs in other body systems. In addition to acute disease a chronic recurring salmonellosis has been reported. Chronic Proliferative Rhinitis was associated with S. ENTERICA subspecies DIARIZONAE. SALMONELLA causes abortion, diarrhea and/or septicemia in goats.
