[Show abstract][Hide abstract] ABSTRACT: In 271 Enterobacter blood culture isolates from 12 hospitals, extended-spectrum beta-lactamase (ESBL) prevalence varied between 0% and 30% per
hospital. High prevalence was associated with dissemination, indicating the potential relevance of infection control measures.
Screening with cefepime or Vitek 2, followed by a cefepime/cefepime-clavulanate Etest, was an accurate strategy for ESBL detection
in Enterobacter isolates (positive predictive value, 100%; negative predictive value, 99%).
