[Pasteurella canis hemorragic sepsis and empyema].

We report the case of a 56-year-old female patient, with a three-day history of hematemesis, melena, abdominal wall hematoma and epistaxis associated with thrombocytopenia and anemia. Idiopathic thrombocytopenic purpura was diagnosed and she was treated with dexamethasone for four days. The patient developed acute respiratory failure with signs of systemic inflammatory response. Blood and pleural fluid cultures grew Pasteurella canis. This is the first case, to our knowledge, of P. canis empyema associated with hemorrhagic septicemia without epidemiological background and the third case of septicemia caused by P. canis reported in the literature.
