The CLSI's (Clinical and Laboratory Standards Institute) recommend ampicillin susceptibility can predict piperacillin and imipenem susceptibilities in E. faecalis, which has been questioned by some reports, such as Tan et al. This study indicated that ampicillin susceptibility cannot accurately predict piperacillin and imipenem susceptibilities in penicillin-resistant, ampicillin-susceptible (Pen-R, Amp-S) E. faecalis,which was non-β-lactamase.
