Molecular Epidemiology and Risk Factors for Extended-Spectrum β-Lactamase–Producing Enterobacterales in Long-Term Care Residents

We aimed to assess the burden of extended-spectrum β-lactamase (ESBL)-producing Enterobacterales in Swiss long-term care facilities (LTCFs) to describe the molecular epidemiology, describe the intrainstitutional and regional clusters of resistant pathogens, and identify independent institution- and resident-level factors associated with colonization.
