A total of 248 isolates were tested; VRE (n = 139) comprised human clinical isolates (n = 41) and isolates from contacts of index patients (n = 63), the environment (n = 33), and animals (n = 2); other Enterococcus spp. (n = 109) included clinical isolates (n = 89) and isolates from animals (n = 20). Refer to text for discussion on the prevalence of VRE from clinical isolates.
Vancomycin MIC, ≤4 μg/ml.
E. durans (n = 2) and E. hirae (n = 2).
