Federal Register. H7 and Salmonella from beef carcass sponge samples and bovine fecal and hide samples, J. With high levels of Salmonella exposure and potentially low levels of immunity, many different strains of Salmonella may be capable of causing disease. The MVDL, located at the University of Minnesota in St Paul, Minnesota, receives animal diagnostic submissions predominantly from farms within the state of Minnesota and ranks 3 in swine production and 6 in dairy production among all states in the country. However, care must be taken when comparing trends of resistance to antimicrobials considered separately as performed here or in the NARMS reportssince simultaneous resistance to other antibiotics may have a major effect on these trends over time [ 12 ]. Salmonella serotypes recovered from feces of commercial feedlot cattle that were sampled as they were treated for apparent respiratory disease. Griffin D.
Table 1 Criteria used for qualitative assessment of the susceptibility of Salmonella isolates recovered from cattle and swine samples for antimicrobials in which resistant isolates were found.

Characterization of multidrug resistant Salmonella recovered from diseased animals. A possible explanation for some of the temporal changes in serotype and AMR prevalence could include a systematic bias derived from the potential variability on the sampled population due to changes in the swine and cattle farms submitting samples to the MVDL.
