Interpretive Summary: Salmonella enterica are a leading cause of enterocolitis for humans and animals. While Salmonella infections are usually self-limiting, more severe infections can occur in susceptible populations (infants, elderly, immunocompromised individuals) and, when caused by drug-resistant Salmonella, treatment options are limited. Dublin are noted as a cattle-adapted Salmonella serotype, but they can cause disease in humans. A recent report on the epidemiology of S. Dublin demonstrates an increasing trend towards multidrug resistance in strains isolated from humans in the U.S. from 1968 - 2013, and that infections caused by this serotype are more likely to be invasive than infections caused by other common Salmonella serotypes. However, the genetic determinants contributing to this invasive phenotype are not well understood. In order to facilitate comparative genomics studies examining the virulence traits and drug resistance determinants of this serotype, we present the complete closed genome and plasmid sequences for three multi-drug resistant (MDR) S. Dublin strains isolated from cattle at harvest.

Technical Abstract: Salmonella enterica serovar Dublin is a host-adapted pathogen for cattle that can cause invasive disease in humans. To facilitate genomic comparisons characterizing virulence determinants of this pathogen, we present the complete genome sequences of three S. Dublin strains isolated from bovine sources at harvest.
