Abstract
Background
We aimed to fill the gaps of knowledge concerning incidence rates and temporal trend, clinical features and risk factors for death for M. morganii bloodstream infections in south Sweden.
Methods
This was an observational, population-based study including all patients with at least one blood culture positive for Morganella morganii between 2013-2023 in Skåne, south Sweden.
Results
A total of 211 episodes of Morganella morganii bloodstream infection in 201 patients were registered during the study period. A urinary tract focus BSI was associated with reduce risk of 90-day mortality (p = 0.0029) whereas a primary BSI was associated with 90-day mortality (p = 0.0112). A multivariate analysis including age,... (More)

A total of 211 episodes of Morganella morganii bloodstream infection in 201 patients were registered during the study period. A urinary tract focus BSI was associated with reduce risk of 90-day mortality (p = 0.0029) whereas a primary BSI was associated with 90-day mortality (p = 0.0112). A multivariate analysis including age, gender, CCI, and immunosuppression revealed that higher CCI (OR 1.25, 95% CI 1.07-1.47, p = 0.0059) and immunosuppression (OR 3.26, 95% CI 1.45-7.47, p = 0.0045) was independently associated with all-cause mortality.
Conclusion
Morganella morganii bloodstream infection is the elderly's disease, most often acquired in individuals with comorbidities that are in close contact with healthcare. A urinary tract focus was associated with reduced risk of 90-day mortality, and higher CCI and immunosuppression was associated with 90-day all-cause mortality in a multivariate analysis. (Less)
