Antimicrobial resistance trends in Escherichia coli isolated from diseased food ‐producing animals in France: A 14‐year period time‐series study

Summary Antimicrobial resistance (AMR) among bacteria isolated from food‐producing animals is a growing concern with implications for public health. AMR surveillance is essential to identify resistance trends and help in the design of effective and efficient control strategies. The aim of the study was to describe the antimicrobial susceptibility of pathogenic Escherichia coli isolated from three livestock productions in France (cattle, swine and poultry). The trend in resistance to the most commonly prescribed antibiotics in animal health was analysed as follows: amoxicillin (penicillin), spectinomycin or streptomycin (aminoglycoside), tetracycline and trimethoprim‐sulfamethoxazole/Enrofloxacin and ceftiofur were also taken into account as members of critically important antimicrobial families in human and veterinary medicine, that is fluoroquinolones and third‐generation cephalosporins, respectively. Data collected between 2002 and 2015 by the French national surveillance network of AMR referred to as RESAPATH were analysed. Resistance trends were investigated using non‐linear analysis (generalized additive models) applied to time‐series stratified by livestock production and antibiotic. Irrespective of the species and the antibiotic considered, resistance signals over time showed no significant annual cycle. Resistance to third‐generation cephalosporins emerged during the period of the study, with a peak at 22% [20.5; 24.0] in poultry in 2010, decreasing afterw...
