Pasteurella Bacteremia: Clinical Presentation, Outcomes, and Mortality in a Retrospective Cohort

Pasteurella species are facultatively anaerobic Gram-negative coccobacilli residing in the upper respiratory tract of mammals, fowl and domestic animals including cats and dogs. Localized infections with Pasteurella species are common but invasive infections are rare. There is a paucity of data available on risk factors, clinical presentations and outcomes with Pasteurella bloodstream infection. We conducted a retrospective review of patients with Pasteurella bacteremia presenting to our institution. There were 63 presentations (61 patients) with Pasteurella bacteremia. Immunosuppression, malignancy and alcohol misuse were common. Rates of admission to intensive care (n = 18, 29.5%) and death prior to hospital discharge (n = 7, 11.5%) were high.
