Abstract
A national surveillance study was performed in order to identify the enterococci causing important infections, to determine their susceptibilities to first-choice agents for treatment, and to characterize the phenotypes and genotypes of the glycopeptide-resistant strains. A total of 472 isolates were collected between 15 January and 15 April 1993. The ability of the API rapid ID 32 STREP gallery to identify enterococci was evaluated. The majority of the Belgian enterococci were identified as E. faecalis (89.4%). E. faecium and other enterococci were present in small percentages only (9.1 and 1.5%, respectively). The API rapid ID 32 STREP system identified 88.6% of the strains with an excellent or very good identification score. For the majority of the strains with uncertain identification scores, the results of a single test only were aberrant. Only 2.3% of the strains remained unidentified. High-level aminoglycoside resistance was widespread in E. faecalis (streptomycin, 50.8%; gentamicin, 8.7%), and the emergence of ciprofloxacin resistance was found to be associated with aminoglycoside resistance. E. faecium is generally more resistant to a wide range of antibiotics, but glycopeptide-resistant strains (1.5%) have not yet become widespread.
