Shipping fever pasteurellosis and salmonellosis prophylaxis.

A water-in-oil emulsion adjuvanted combination shipping fever bacterin containing Pasteurella multocida, P hemolytica, Salmonella typhimurium and certain other species was effective in field use as a prophylactic agent against shipping fever pasteurellosis and salmonellosis. In trials using ranch calves it produced a greater antibody response than a comparable aluminum hydroxide adjuvanted bacterin. In critical 30-hour postvaccination challenge mouse tests it was superior to the conventional type bacterin and induced rapid and remarkable protection.
