Interpretive Summary: Salmonella Kentucky is frequently isolated from food producing animals, such as poultry and dairy cows, and it is also known to cause human illness. Generally cows and poultry do not show any signs of illness when they are infected with this pathogen. We don’t yet understand the mechanisms involved in the persistent carriage of S. Kentucky (or other serotypes) and therefore are unable to mitigate it’s prevalence in production animals. Recent research using next generation sequencing technologies has shown that there is a lot of diversity within the Kentucky serotype. We sequenced the genome of two S. Kentucky isolates from poultry carcasses. Both isolates were both categorized in the same general group (ST152) but they had different genomic features. One isolate did not have any antibiotic resistance genes and it was shown to be susceptible to a panel of 25 antibiotics. The genome of the second isolate contained genes responsible for resistance to two classes of antibiotics, aminoglycosides and sulphonamides. Neither isolate contained the multi-drug resistance region known as the Salmonella Genomic Island-1, that is typically found in isolates within the ST198 group. This work furthers our understanding of the salmonellae that are found to persist in food producing animals.

Technical Abstract: We report the draft genomes of two Salmonella Kentucky eBurstGroup-15 isolates collected from poultry carcasses in Georgia (USA).
