Abstract
β-Lactamase production was detected in 147 (52%) of 282 consecutive nonduplicate Proteus mirabilis isolates obtained over a 1-year period from the S. Matteo Hospital of Pavia (northern Italy). Seventy isolates (48% of the β-lactamase producers) were found to produce extended-spectrum β-lactamases (ESBLs), identified as PER-1 (first report in this species) and TEM-52 in 52 and 18 isolates, respectively. Analysis of clonal diversity of the ESBL producers suggested different spreading patterns for the two ESBL determinants.
