What’s up ducks? – antimicrobial resistance of Escherichia coli isolated from duck farm environment in Poland extended with genomic characteristics of cephalosporin-resistant strains

A study in Poland evaluated antimicrobial resistance (AMR) in Escherichia coli from duck farms. The researchers isolated 340 strains from boot swabs collected at 306 duck farms, screening for indicator, cephalosporin-, carbapenem-, and colistin-resistant E. coli. The study found that 81.1% of the E. coli were resistant, with ciprofloxacin, ampicillin, tetracycline, and nalidixic acid resistance being the most frequent. The study also found numerous AMR determinants in the duck farm environment, including those of public health concern.
