In Reply.—Dr Schwartz has referred to two articles in which complications are described after dog and cat bites. Although these articles clearly describe the role of P multocida in cellulitis and abscesses, none of the cases provide conclusive evidence of P multocida osteomyelitis. In two of the cases reported by Allott et al,1 osteomyelitis developed after dog bites.1 However, in both cases, Staphylococcus aureus, as well as P septica (currently known as P multocida), grew from bone cultures.2 The exact role of each of these organisms in the pathogenesis of the osteomyelitis is unclear.

In the cases reported by MacCabe and Conn,3 either roentgenographic evidence of osteomyelitis was lacking, or bone cultures were not reported. In contrast, our cases were supported by both roentgenographic evidence of osteomyelitis and bone cultures from which P multocida was isolated.

More importantly, our cases demonstrated that when there was
