title: Species identification and antibiotic resistance patterns of the enterococci.
abstract: One hundred and forty isolates were identified using the GPI Card (Vitek Systems) and a conventional biochemical scheme. Agar dilution susceptibility testing was performed and isolates were screened for beta-lactamase production. The GPI Card was accurate in identifying Enterococcus faecalis, but discrepant results were obtained for seven (29.1%) of the 24 non-Enterococcus faecalis isolates. Ampicillin resistance was present in 2.9% of isolates and there were no beta-lactamase producers. There was no vancomycin resistance but 12.1% of isolates showed high-level resistance to gentamicin.
