Septic shock due to Pasteurella multocida bacteremia: A case report

Introduction: Pasteurella is a Gram-negative coccobacillus that causes a wide spectrum of diseases in humans and is commonly transmitted from cat and dog bites. An increasing number of cats and dogs are kept as pets in American households which increases the risk of pet-related infections. Case presentation: An 82-year-old African American woman with multiple comorbidities presented with fever, vomiting and diarrhea; she later developed septic shock requiring vasopressors and intubation. She was found to have Pasteurella multocida bacteremia. Her hospital course was complicated by a pulseless electrical activity arrest. She had exposure to her pet cat at home. We believe that a possible portal of entry was her skin; however, other possibilities such as respiratory tract could not be excluded. She was treated with imipenem-cilastatin and discharged after 25 days. Conclusions: Studies have shown a mortality range from 7 to 31% in Pasteurella bacteremia. Due to an increasing number of pets and high mortality of this disease, it is important to have a high suspicion for this infection, especially in elderly and immunocompromised patients. © 2015 Narsana and Farhat.
