Pasteurella multocida, a small gram-negative coccobacillus, is part of the normal oral flora of many animals, including the cat and dog. P. multocida is a major pathogen in wound infections due to animal bites and can cause cellutitis, abscess, osteomyelitis, septic arthritis, or a variety of other infectious syndromes (Table 1). Over the years, P. multocida has been the subject of a number of short general reviews (74, 80, 91, 96, 158). More recently, reviews have focused on selected aspects of P. multocida infection including meningitis (44), empyema (112), spontaneous bacterial peritonitis (160), bone and joint infections (56), and septicemia (111). A large series of cases with a comprehensive review, however, has not been published. We therefore report here 34 cases from the Massachusetts General Hospital and review the English literature
