Evolutionary tree showing the phylogenetic relationships between C. lari, C. doylei, C. coli and C. jejuni retrieved from RDP-II and the nine sequence types (Seq type) of Campylobacter spp. identified in this study. A representative strain is given in brackets after the sequence types. Accession numbers in GenBank are given for the other strains. Camplyobacter upsaliensis was used as outgroup. The length of the scale bar represents 1 nucleotide substitution per 100 positions.
