Coliform mastitis in sows: A review

Abstract

Coliform mastitis (CM) represents an economically very important disease complex in sows that also affects the health, welfare, and performance of the piglets. Most research has concentrated on the husbandry-influenced occurrence of CM. The pathogenesis of CM suggests a prominent role for Escherichia coli and its endotoxins, although other Enterobacteriaceae species have been isolated from affected animals. Most studies on CM were conducted between 1970 and 1990. It is time for a closer look at this disease, particularly with respect to the economic damage it causes and the lack of recent literature. Treatment and use of body temperature as a single indicator for diagnosis of CM must be regarded critically. A combination of appropriate criteria should be applied to achieve a proper diagnosis and to minimize use of antibiotics. Additional approaches, for instance, incorporating knowledge concerning virulence factors of E coli, are promising tools for future prevention.
