ABSTRACT

Background: Escherichia coli is the main pathogen associated with bloodstream infections. Bacteremia due to multidrug resistant pathogens has increased worldwide. In Mexico, epidemiological data from hospital setting is invaluable. Objective: The arm of this anode the epidemiology of Escherichia coli bacteremia in was conducted the ABC Medical Center. Material and methods: A retrospective cohort study, bacteremia were included 98 patients for to 18 years old, with Escherichia coli bacteremia here included, hospitalized between January 1, 2014 and December 31, 2014, in both campus of the ABC Medical Center. Clinical, microbiological features and treatment were characteristics. We cases here classified according to bacteremia onset: community and hospital acquired. The main outcomes were the length of stay and mortality. Results: During 2014, 98 cases of Escherichia coli blood stream infections were identified in ABC Medical Center. Eighty-two patients (83.7%) were classified as community onset while only 16 (16.3%) were hospital onset. Fourteen (17%) community-onset cases were health-care associated bacteremias. Crude mortality was 9.3% (7.3% for community onset; 20% for hospital onset infections). All deaths from community onset cases were on patients with healthcare associated infections. Extended spectrum beta-lactamase Escherichia coli was isolated in 43 (43.9%) cases, 31 (37.8%) of community onset versus 12 (75%) of hospital onset. Conclusions: The epidemiology of Escherichia coli bacteremia in ABC Medical Center are akin to other reports, though the percentage of extended spectrum beta-lactamases Escherichia coli infections is more than double of the one reported in developed countries.
