| description | <p>Abstract</p> <p>Background</p> <p><it>Arcobacter</it> spp. (family <it>Campylobacteraceae</it>) are ubiquitous zoonotic bacteria that are being increasingly recognised as a threat to human health. A previously published 16S rRNA-RFLP <it>Arcobacter</it> spp. identification method produced specific RFLP patterns for the six species described at that time, using a single endonuclease (<it>Mse</it>I). The number of characterised <it>Arcobacter</it> species has since risen to 17. The aim of the present study was to update the 16S rRNA-RFLP identification method to include all currently characterised species of <it>Arcobacter.</it></p> <p>Results</p> <p>Digestion of the 16S rRNA gene with the endonuclease <it>Mse</it>I produced clear, distinctive patterns for 10 of the 17 species, while the remaining species shared a common or very similar RFLP pattern. Subsequent digestion of the 16S rRNA gene from these species with the endonucleases <it>Mnl</it>I and/or <it>Bfa</it>I generated species-specific RFLP patterns.</p> <p>Conclusions</p> <p>16S rRNA-RFLP analysis identified 17 <it>Arcobacter</it> spp. using either polyacrylamide or agarose gel electrophoresis. Microheterogeneities within the 16S rRNA gene, which interfered with the RFLP identification, were also documented for the first time in this genus, particularly in strains of <it>Arcobacter cryaerophilus</it> isolated from animal faeces and aborted foetuses.</p> |
