Research Project: Evaluation of the Spatial and Longitudinal Distribution of Antimicrobial Resistance Genes and Occurrence of Potential Horizontal Gene Transfer...

Location: Meat Safety and Quality

Project Number: 3040-32000-035-001-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Jan 1, 2021
End Date: Dec 31, 2023

Objective:
The objectives of the research is to understand the potential for antimicrobial resistance transmission in beef cattle production in high health risk cattle at receipt to the feedlot following metaphylactic treatment.

Approach:
ARS investigators will analyze bacterial isolates from samples collected from high health risk beef cattle to determine the antimicrobial resistance in commensal and pathogens and the potential role for horizontal gene transmission in the dissemination of antibiotic resistance to pathogenic bacteria. ARS scientists will analyze samples of feces from these cattle to monitor for antibiotic resistant E. coli and Salmonella, and provide a sub-sample to UNL for bacterial whole genome sequencing.
