Spread in an Italian Hospital of a Clonal Acinetobacter baumannii Strain Producing the TEM-92 Extended-Spectrum beta-Lactamase.

Clinical isolates of Acinetobacter baumannii (n = 470) were collected during a 7-year period and investigated for the genetic determinants of resistance to expanded-spectrum ß-lactams. Thirty-one isolates produced the TEM-92 extended-spectrum ß-lactamase (ESBL) and were clonally related. This is the first report of A. baumannii producing a TEM-type ESBL.
