FIG. 4.

Neighbor-joining phylogenetic tree for Helicobacter spp. isolated from feces of cats and reference Campylobacter and Helicobacter species. The scale bar represents phylogenetic distance as estimated using the Jukes Cantor correction. Distances can be determined by adding the lengths of all of the horizontal lines connecting any two species. GenBank accession numbers appear in brackets. The 1,200-bp partial sequences (marked as such) for which accession numbers are not provided were not deposited in GenBank and are available from the corresponding author.
