“…This situation not only increases the difficulty of treating animal diseases like those caused by APEC with existing anti‐microbials, but it also poses a potential threat to human health in consideration of the cross exchange of drug‐resistance genes between animal and human pathogens (Collignon, Wegener, Braam, & Butler, ). Unfortunately, consistent with previous studies (Chen et al., ; Wang et al., ), the isolates in this study carried multiple drug‐resistance genes. Thus, to control APEC in poultry is a challenge, especially for the MDR strains, and requires further study.…”

Avian pathogenic Escherichia coli (APEC) causes high mortality in poultry flocks and often is complicated with viral infections, leading to large economic losses; however, little information is available on the epidemiological characteristics of this pathogen in ducks. Therefore, a systemic epidemiological investigation was performed on 325 duck farms from 13 provinces in China during the period of 1 April 2016 until 31 March 2018, covering 2 years. A total of 26 APEC strains were isolated from different farms in this study, and analysis showed that all of those isolates carried multiple virulence‐associated genes and drug‐resistance genes, which led to high pathogenicity (15/26), strong or moderate biofilm formation (24/26) and multidrug‐resistant abilities (26/26). On the other hand, coinfection with APEC, H9 avian influenza virus (AIV) and Tembusu virus (TMUV) was very common on those farms (11/26), with APEC and TMUV sharing a similar morbidity peak (from May to September) and susceptibility (60% infections occurred in ducklings); thus, we speculated that the emerging TMUV infection escalated the APEC incidence in ducks. Finally, the data presented in this report enhance the current understanding of the epidemiology of APEC and different viral infections in ducks and provide additional insight into the critical factors that determine their pathogenicity. Meanwhile, the emergence of multidrug‐resistant APEC strains and their coinfection with different viruses emphasize that preventive measures against such infections on poultry farms should be implemented immediately.

“…Studies of antibiotic resistance in E. coli isolated from chickens indicate that ARGs have spread widely (Kilonzonthenge et al 2013;Zhang et al 2013;Chen et al 2014;Wu et al 2014;Koga et al 2015;Wolny-Koladka and Lenart-Boron 2016). In our experiments, we found that the antibiotic susceptibility in E. coli isolated from chickens was high.…”

“…Nevertheless, this study succeeded in providing an overview of changing resistance trends. To our knowledge, this is also the first paper exploring AMR trends in farm animals over such a long period of time and based on such a large data set, compared with previous findings (Chen et al., ; Hanon et al., ). Moreover, this study is the first to investigate antibiotic resistance with its temporal component in France.…”

“…Few studies have so far investigated resistance trends in bacterial isolates from animals, and these mostly in poultry and companion animals (Chen et al., ; Cohn, Gary, Fales, & Madsen, ; Normand, Gibson, Reid, Carmichael, & Taylor, ). These studies mostly used chi‐square tests to analyse the data.…”

SummaryAntimicrobial 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 ac- These results contribute to risk assessment and constitute objective evidence on which to evaluate the efficacy of control measures implemented to limit AMR occurrence.
