Sepsis Caused by Extended-Spectrum Beta-Lactamase (ESBL)-Positive K. pneumoniae and E. coli: Comparison of Severity of Sepsis, Delay of Anti-Infective Therapy and ESBL Genotype.

Infections with extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) are associated with increased mortality. Outcome differences due to various species of ESBL-E or ESBL genotypes are not well investigated. We conducted a cohort study to assess risk factors for mortality in cases of ESBL-E bacteremia (K.

Costs and length of stay associated with extended-spectrum β-lactamase production in cases of Escherichia coli bloodstream infection.

The prevalence of infections with extended-spectrum β-lactamase (ESBL)-producing bacteria is increasing worldwide. The economic burden of this development has not yet been sufficiently studied. Therefore, this study on hospital costs and length of stay (LoS) associated with cases of bloodstream infection (BSI) due to ESBL-producing Escherichia coli was performed.

Mortality and molecular epidemiology associated with extended-spectrum β-lactamase production in Escherichia coli from bloodstream infection.

Background: The rate of infections due to extended-spectrum β-lactamase (ESBL)-producing Escherichia coli is growing worldwide. These infections are suspected to be related to increased mortality. We aimed to estimate the difference in mortality due to bloodstream infections (BSIs) with ESBL-positive and ESBL-negative E.
