Yersinia pseudotuberculosis is a common inhabitant of the intestine in a wide variety of animals. It is spread via the faeces on pasture and in water. Yersinia causes enteritis as a result of heavy infection pressure in animals debilitated from other influences, these include cold wet weather, starvation, and lack of water, change of diet, concurrent disease, and management procedures such as yarding or transport. Outbreaks of enteritis are more common in young stock during the winter, early spring. Humans may contract Yersinia infections from animals.
Minimise affect of stressors such as transportation, deprivation of feed and water, management procedures, dietary changes, mineral deficiencies, concurrent disease such as BVD virus infection, and climate. There is no specific control in cattle but the maintenance of good nutrition is an important factor in avoiding clinical disease.
Antibiotics, fluid replacement therapy, good nutrition. Different strains of Yersinia vary in their sensitivity to antibiotics and a test to determine which antibiotic is most suitable is recommended.
