Investigation of the Antimicrobial Resistance of Important Pathogens Isolated from Poultry from 2015 to 2023 in the United States

Foodborne pathogens cause 47.8 million illnesses in the U.S. annually, with antimicrobial misuse in food production, particularly poultry processing, contributing to this public health challenge. Misuse of antimicrobials can lead to antimicrobial resistance (AMR), making treatment difficult. A study analyzed data from the NCBI Pathogen Isolates Browser to explore the relationships between antimicrobial-resistant pathogens, AMR genes, and antimicrobials detected with resistance in chicken and turkey. Salmonella enterica was the most prevalent AMR pathogen, with Campylobacter jejuni more prevalent in chicken. Key AMR genes, such as tet(A), mdsA, and mdsB, showed a decline by 2022.
