Unusual infections caused by Pasteurella multocida.

Three cases of infection with Pasteurella multocida included acute epiglottitis, septic arthritis, and pleuropulmonary infection. Human infections with this microorganism are commonly related either to animal contact (eg, wound infections) or to the presence of underlying chronic respiratory tract disease. Although septic arthritis and pleuropulmonary infections have previously been attributed to this pathogen, to our knowledge, this is the first reported case of acute epiglottitis caused by P. multocida.
