Enterococci are frequently associated with hospital-acquired infection. Identification of enterococci using conventional biochemical tests are often tedious to perform in a routine diagnostic laboratory and may give equivocal results. This study evaluates the usefulness of ribotyping by DNA hybridisation to identify 68 members of the bacterial genus Enterococcus characterised by a conventional test scheme. DNA probes (830 bp in size) were derived from the 16S rRNA gene of E. coli or E. faecalis by PCR, labelled with horseradish peroxidase and used in Southern blot hybridisations of enterococcal DNA digested with EcoRI. Unique ribotypes were obtained for 11 different species using 12 Enterococcus type strains. Ribotyping identified 44 E. faecalis isolates, 19 E. faecium isolates, two E. durans isolates and one E. avium isolate in concordance with results of the biochemistry tests. Two isolates that had ribotype patterns identical to the E. faecium type strain were unable to be definitively identified by biochemical tests. The results show that ribotyping is able to differentiate between E. faecium and E. faecalis and may be useful for identifying other enterococci in the hospital setting. In addition, ribotyping using DNA probes and enhanced chemiluminescence is a safe and more reproducible alternative to radiolabelling RNA in a clinical microbiology laboratory.
