Genome size variation and estimated N50 sizes within Salmonella Montevideo draft genome sequences. The estimated N50 value is a rough estimate of the quality and coverage of the draft genomes which was sequenced to approximately 15-20× coverage. The N50 value represents the average contig size after assembly with the Newbler software. Isolate names correspond to samples in Table 1. Genome length ranged from less than 4.45 mbp to about 4.75 mbp, with most isolates approximately 4.65 mbp in size (unlabeled boxes). Only the larger or smaller genomes are listed.
