Description
Summary:Although Providencia species are recognised as important causes of bloodstream infections (BSI), their epidemiology is not well defined due to their infrequent occurrence. Our objective was to determine the overall incidence, determinants, and outcomes of Providencia species BSI, and compare the epidemiology of P. stuartii and P. rettgeri in a large population. All patients within Queensland, Australia with Providencia species BSI between 2000-2019 were included with clinical and outcome data collected from state-wide datasets. Among 268 residents, there was 273 incident episodes of Providencia species BSI; with 118 cases (43.2%) due to P. rettgeri, 150 cases (55.0%) due to P. stuartii, for age and sex adjusted incidence rates of 1.5, and 2.1 per million respectively. Five cases (
