Pasteurella vaccines: Common mistakes and how to avoid them

摘要

Pasteurellosis, also known as "enzootic pneumonia", remains one of the most common causes of mortality in sheep of all ages. Despite its impact, the disease is still not wholly understood.The bacteria responsible have been reclassified recently as Mannhemia haemolytica and Bibersteinia trehalosi. Both are normal inhabitants of the nose and throat of healthy sheep. When sheep become stressed, however, these bacteria take a leap into the lower respiratory tract (lung), causing pneumonia and septicaemia. The most common sign is, unfortunately, sudden death.
