Phylogenetic tree constructed with the partial 16S rRNA gene sequences of 20 sequenced Arcobacter products. Campylobacter jejuni subsp. jejuni (GenBank accession no. M59298) was used as an outgroup. Bootstrap values of >50% are shown. The scale bar corresponds to 0.1 substitution per nucleotide position. The strain names are marked in bold letters: EUC, VIL, and WH denote Euclid, Villa Angela, and West Headlands, respectively, followed by the sampling dates. The numbers in parentheses are GenBank sequence accession numbers.
