What is the best method? Recovery of methicillin-resistant Staphylococcus aureus and extended-spectrum β-lactamase-producing Escherichia coli from inanimate hospital surfaces.

Environmental sampling in hospitals, when required, needs to be reliable. We evaluated different methods of sampling methicillin-resistant Staphylococcus aureus and extended-spectrum β-lactamase-producing Escherichia coli on 5 materials of the hospital setting. Petrifilms and contact plates were superior to swabs for all of the surfaces studied.
