FIG 1.

(A) Neighbor-Net algorithm used for constructing phylogenetic networks generated with the 1,404 shared loci of the six milk-borne C. jejuni outbreak-associated isolates and two unrelated control strains (C. jejuni PT14 and 1_12S). (B) Neighbor-Net phylogeny generated with the 1,432 shared loci of the six milk-borne isolates. The boldfaced numbers indicate the distances (numbers of allelic differences) between the isolates. For the pairwise comparison of the isolates, see Tables S2 and S3 in the supplemental material.
