Risk factors associated with extended-spectrum β-lactamase-producing Enterobacteriaceae carriage at admission in an infant cohort at a tertiary teaching hospital in France.

We describe risk factors associated with extended-spectrum β-lactamase-producing Enterobacteriaceae fecal carriage at admission in an infant population. 12.6% were carrying extended-spectrum β-lactamase-producing Enterobacteriaceae.

Environmental contamination with extended-spectrum β-lactamases: is there any difference between Escherichia coli and Klebsiella spp?

Background: The hospital environment contributes to the spread of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-PE) during outbreaks. We aimed to assess the rate of environmental contamination in rooms occupied by ESBL carriers or infected children and to identify risk factors associated with contamination.

Methods: Five environmental surface samples were systematically performed in rooms occupied by ESBL-PE carrier or infected children.
