title: Vaccination strategies for reducing clinical severity of coliform mastitis.
abstract: Brief history and extensive published field efficacy data of the two rough ("R") bacterial mutants utilized in commercial preparations of the core antigen bacterins Escherichia coli O111:B4 (strain J5) and Salmonella typhimurium Re-17 are summarized. Particular dosage schedules and routes of administration of coliform mastitis bacterins are compared for their associated ecacy. Practical concerns in employing a coliform mastitis vaccination program are discussed. Characteristics of farms using coliform mastitis vaccination and suggested guidelines for whether individual dairy herds should adopt this practice are presented for consideration.
