Two strains, designated 64T and 122, were selected for
further genomic analysis. DNA–DNA hybridizations were
performed with photobiotin-labelled probes in microplate
wells as described by Ezaki et al. (1989), using a HTS7000
Bio Assay Reader (PerkinElmer) to measure fluorescence.
DNA–DNA hybridization experiments, performed at
30 uC, showed that strains 64T and 122 exhibited a mean
DNA binding level of 72 %. Mean DNA–DNA relatedness
between strains 64T and 122 and type strains of related
Arcobacter species were as follows: 47% (A. cryaerophilus
LMG 9904T), 38% (A. skirrowii LMG 6621T), 38% (A.
thereius LMG 24486T), 36% (A. cibarius LMG 21996T) and
31% (A. butzleri LMG 10828T)
