FIG. 2.

One of four most parsimonious trees inferred from analysis of sequences from the LMO, VGC, and INL regions (Table 3). The analysis included sequences from all 48 lineage III and IV isolates examined (identified by NRRL-B numbers) and unique sequence types identified in the SNP discovery for lineages I (5) and II (Table 1). The LMO sequence from Listeria innocua strain Clip11262 (NC_003212) was used to root the tree. The frequency (percentage) with which a given branch was recovered in 2,000 bootstrap replications is shown above branches recovered in more than 70% of bootstrap replicates. Similar results were obtained with neighbor-joining analysis.
