Clinical manifestations, risk factors and prognosis of patients with Morganella morganii sepsis

Abstract

Background: There are few studies of Morganella bacteremia. We evaluated risk factors and outcome of patients with Morganella bacteremia. Methods: Medical records of patients with Morganella bacteremia were reviewed (1997–2014). Control group patients with Escherichia coli sepsis were matched by year of diagnosis and infection acquisition site. Results: The study group included 136 adult patients. Mean age and gender of study and control groups were similar. Complicated soft tissue infection was more prevalent in the study group (30% versus 3.2%, p 4, septic shock and a clinical syndrome other than UTI were all significant risk factors for mortality (p < 0.05). Conclusions: Patients with Morganella morganii sepsis had more co-morbidities and a worse degree of sepsis. There is an increased risk of inappropriate empirical treatment, longer hospitalization and higher death rate.
