Abstract

Using calves immunized with P. haemolytica serotype 1 and challenged by intrabronchial infusion of the homologous organism, the adverse effects of parenterally injected whole cell bacterins has been confirmed experimentally. Successful vaccination of calves to prevent Pasteurella-induced fibrinous pneumonia apparently cannot be accomplished by the simple expedient of parenteral injection of formalin killed bacterial cells.
