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.

Distinct contribution of protein kinase Cδ and protein kinase Cε in the lifespan and immune response of human blood monocyte subpopulations.

Monocytes, key components of the immune system, are a heterogeneous population comprised of classical monocytes (CD16(-) ) and non-classical monocytes (CD16(+) ). Monocytes are short lived and undergo spontaneous apoptosis, unless stimulated. Dysregulation of monocyte numbers contribute to the pathophysiology of inflammatory diseases, yet the contribution of each subset remains poorly characterized.
