Abstract
Although infrequently associated with illness in humans, Salmonella enterica, subsp. enterica serovar Kentucky is the most common non‐clinical, non‐human serovar reported in the United States, being largely found in poultry and poultry products, as well as being associated with cattle. This serovar is polyphyletic and can be separated into two groups, Group I and II, based on CRISPR‐typing analysis. In Salmonella Kentucky isolates from human clinical samples in Pennsylvania, both lineages are equally represented. The goal of this study was to determine whether both groups were also represented in domestic food animals in Pennsylvania. We analysed the CRISPR arrays from 67 SalmonellaKentucky isolates used PCR and sequencing of CRISPR arrays or analysis of whole genome sequences to analyse the CRISPR arrays and Across a collection of 67 SalmonellaKentucky isolates that includes those collected from farms, veterinary clinical samples as well as isolates from retail meats, we show that Group I Salmonella Kentucky are the exclusive lineage present. We reveal that the specific subtype of over a quarter of these animal isolates are also found to be responsible for causing human salmonellosis in the same region over the same time period.
