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.
