Exploring Antimicrobial Resistance Profiles of Isolates in Dairy Cattle: A Baseline Study across Dairy Farms with Varied Husbandry Practices in Puerto Rico.

Antimicrobial treatment in livestock can contribute to the emergence and spread of antimicrobial-resistant (AMR) microorganisms. Despite substantial surveillance of AMR bacteria in the continental United States, the prevalence of these AMR organisms in U.S.

Virulence Potential of Escherichia coli Isolates from a Beef Farm in Puerto Rico.

Sixteen Escherichia coli isolates were obtained from fecal matter from a beef farm in Puerto Rico. Isolates were whole-genome sequenced for characterization, including pathotype characterization, virulence, and plasmid identification. The results of the draft genomes identified potential pathogenic E.
