Abstract
We present the complete, closed, and finished chromosomal and extrachromosomal genome sequences of Yersinia ruckeri strain CSF007-82, the etiologic agent of enteric red mouth disease in salmonid fish. The chromosome is 3,799,036 bp with a G+C content of 47.5% and encodes 3,530 predicted coding sequences (CDS), 7 ribosomal operons, and 80 tRNAs.
Highlights
We present the complete, closed, and finished chromosomal and extrachromosomal genome sequences of Yersinia ruckeri strain CSF007-82, the etiologic agent of enteric red mouth disease in salmonid fish
Successful bacterin vaccines for enteric red mouth disease (ERM) were developed in the 1970s; outbreaks in vaccinated fish have recently occurred and have been associated with the emergence of novel variants of this pathogen [3, 4]
Only two draft Y. ruckeri genomes are available; the genome of the type strain, ATCC 29473T, consists of 174 contigs, while the genome of a strain from Chile consists of 75 contigs [5]
Summary
We present the complete, closed, and finished chromosomal and extrachromosomal genome sequences of Yersinia ruckeri strain CSF007-82, the etiologic agent of enteric red mouth disease in salmonid fish. Successful bacterin vaccines for ERM were developed in the 1970s; outbreaks in vaccinated fish have recently occurred and have been associated with the emergence of novel variants of this pathogen [3, 4]. The reemergence of Y. ruckeri mediated ERM has renewed interest in the virulence and evolution of this pathogen.
