Antimicrobial resistance (AMR) presents a significant threat to human health worldwide. One important source of antimicrobial-resistant infections in humans is exposure to animals or animal products. In a phased survey, we investigated AMR in 300 Escherichia coli isolates and 300 enterococci (Enterococcus faecalis and E.

The study objective was to determine the occurrence and antimicrobial resistance (AMR) attributes of select foodborne bacteria recovered from egg-producing (layer) chickens between 2007 and 2021 using different sample matrices (Study 1: liquid whole eggs, Study 2: spent hen cecal samples, Study 3: environmental sponge swabs and fecal samples from layer chicken barns, and Study 4: fecal samples from layer chicken barns). Samples from each study were submitted for the culture of Escherichia coli and Salmonella. In addition, samples from layer chicken barns were submitted for the culture of Campylobacter.

- * C. jejuni was most commonly found in domestic chicken meat and offal, while C. coli was prevalent in domestic pork offal, with higher rates in offal compared to regular meat.
- * A small percentage of C. jejuni (1%) and a larger percentage of C. coli (36.2%) were resistant to erythromycin, with a significant portion of both species also resistant to ciprofloxacin, linked to a specific genetic mutation.

The emergence of fluoroquinolone and macrolide resistance in C. jejuni, a recognized zoonotic pathogen, has increased worldwide. This study aimed to investigate phenotypic resistance to ciprofloxacin and erythromycin, the molecular mechanisms involved, and the strain of C.
