Introduction

Pasturella pneumotropica are small, gram-negative , oxidase positive bacilli that colonize the mucous membranes of domestic and wild animals but these are not present usually in the normal flora in human beings^[1][2].  Infection in humans is mainly caused by the bites, saliva and scratches of animals^[3][4][5]. Lymphangitis and cellulitis are the common clinical presentation resulting from the direct exposure and that can be complicated by tenosynovitis, osteomyelitis, bone abscess and septic arthritis^[7]. Pasturella speciescan rarely cause localized infectionslike conjunctivitis and Otitis media^[6]. Respiratory tract infectionscan occur due to the inhalation of bacteria^[8].  Many systemic infections likebrain abscess, bacteremia, meningitis and peritonitis and endocarditis can be caused by Pasturella species^[9][10]. Meningitis in infants occur due to the animal contact.Pasturella multocida is the commonest pathogen that is frequently isolated from wounds by animal bites ^[11]. Other Pasturella species are Pasturella pneumotropica, Pasturella haemolytica and Pasturella ureae that can be differentiated on the basis of different biochemical tests and are rare in humans. Here we report a case of Pasturella pneumotropica from a patient with osteomyelitis with a history of dog or cat bites P. pneumotropica was described by Jawetz in 1950 in among rats and mice where it causes various infections^[12].
