Salmonella Heidelberg and Dublin isolates in the Penn State Animal Diagnostic Laboratory Culture Repository were selected and subjected to whole-genome sequence analysis to reveal the unique and shared antimicrobial resistance genes and mobile genetic elements in Heidelberg and Dublin isolates from veal calf operations. Based on the observations, it can be speculated that sharing the same environment could facilitate sharing of plasmids that assist in the dissemination of antimicrobial-resistant genes.
