Abstract
AIMS: Gas chromatographic analysis of cell membrane fatty acid methyl esters (FAME), biochemical profiling (biotyping) and EcoRI restriction endonuclease profiling of DNA containing ribosomal RNA sequences (ribotyping) were compared for differentiation of Enterococcus spp. METHODS AND RESULTS: FAME profiling, biotype profiling and ribotyping of 41 strains from retail Swiss-type cheeses and five strains from culture collections resulted in 17, 25 and 26 groups, respectively, with only two pairs of strains having the same FAME group, biotype profile and ribogroup. CONCLUSION: Substantial overlap occurred in groupings assigned by the three methods. SIGNIFICANCE AND IMPACT OF THE STUDY: Differentiation of Enterococcus spp. strains increases if multiple methods are used.
