Highlights
- •Nosocomial epidemiology of extended-spectrum β-lactamase-producing organisms is not clarified in Japan.
- •We focus on extended-spectrum β-lactamase-producing Escherichia coli and Klebsiella pneumoniae causing nosocomial outbreak.
- •We retrospectively compare the occurrence of these 2 extended-spectrum β-lactamase-producing organisms.
- •Our findings demonstrate an increase in the influx of Escherichia coli from the community.
We examined the results of surveillance of extended-spectrum β-lactamase (ESBL)-producing
Escherichia coli and Klebsiella pneumoniae, which are pathogens known to cause nosocomial outbreaks, at a comprehensive cancer
center in Japan over a 5-year period. We found that the admission prevalence and the
incidence of ESBL-producing E coli increased during the study period, in contrast with ESBL-producing K pneumoniae, in which the parameters remained low throughout the study period.
