Yersinia ruckeri strain ATCC 29473 had been sequenced by other groups using short read sequencing, which resulted in contigs, but no complete, closed circular assemblies. In order to determine which linear contigs are of chromosomal origin, and which are of plasmidic origin, we sequenced this strain with Oxford Nanopore long read sequencing, to get long reads, to "bridge the gaps" between the known contigs.
