title: The role of Mannheimia species in ovine mastitis.
abstract: Mannheimia haemolytica is known to be an important cause of intramammary infection in sheep. It usually causes severe clinical mastitis, followed by toxaemia and gangrenous necrosis of the udder. However there are limited data available on the epidemiology and pathogenesis of mastitis associated with Mannheimia species. These organisms can be more significant as a cause of mastitis than Staphylococcus aureus in some flocks. Some data suggest the possibility of horizontal transmission of Mannheimia species between ewes via lamb sucking. There is no vaccine available for prevention, and the sudden onset of mastitis and its peracute nature renders most treatments unsuccessful. This review examines the significance of the species within this genus in sheep mastitis.
