Pasteurella multocida Bacteremia in an Immunocompromised Patient After Multiple Cat Scratches.

(P. multocida) is a zoonotic organism found in the normal flora of domestic and wild animals. In this case report, we present a 70-year-old Caucasian male who presented with fever, chills, and greenish sputum which began hours prior to presentation. His symptoms were initially thought to be due to refractory pneumonia because the patient had been discharged from our hospital three weeks prior to presentation. Blood cultures grew , a rare pathogen to cause bacteremia. He was treated with cefepime and later amoxicillin/clavulanic acid and made an uneventful recovery. Later history of the patient's cats scratching him was thought to be the mode of transmission. infection is rare, and can also be dangerous and even fatal in immunocompromised individuals. Clinicians must therefore operate with a high degree of suspicion especially when treating immunocompromised patients with bacteremia.
