The fasta files (Genome_Set01.zip) contain the reference-assisted de novo assemblies (as contigs) of four Campylobacter spp. isolates. The table contains rows as isolates (yellow) and columns as attributes (green) for each individual genome. This dataset is associated with the following publication: Gomez-Alvarez, V., N. Ashbolt, J. Griffith, J. Santo Domingo, and J. Lu. Whole-Genome Sequencing of Four Campylobacter strains Isolated from Gull Excreta collected from Hobie Beach (Oxnard, CA, USA). Microbiology Resource Announcements. American Society for Microbiology, Washington, DC, USA, 8(32): e00560-19, (2019).
