In vitro activities of selected new and long-acting cephalosporins against Pasteurella multocida.

The activities of six agents commonly used in treating infections of the skin and soft tissues and the action of selected cephalosporins against 15 isolates of Pasteurella multocida were assessed by a macro-broth dilution method. Broad-spectrum cephalosporins, including ceftriaxone and cefixime, had excellent in vitro activities (MIC less than or equal to 0.098) against the isolates tested.
