Epidemiological Prevalence of Phenotypical Resistances and Mobilised Colistin Resistance in Avian Commensal and Pathogenic E. coli from Denmark, France, The Netherlands, and the UK

Colistin has been used for the treatment of non-invasive gastrointestinal infections caused by avian pathogenic E. coli (APEC). The discovery of mobilised colistin resistance (mcr) in E. coli has instigated a One Health approach to minimise colistin use and the spread of resistance. The aim of this...

description Colistin has been used for the treatment of non-invasive gastrointestinal infections caused by avian pathogenic E. coli (APEC). The discovery of mobilised colistin resistance (mcr) in E. coli has instigated a One Health approach to minimise colistin use and the spread of resistance. The aim of this study was to compare colistin susceptibility of APECs (collected from Denmark n = 25 and France n = 39) versus commensal E. coli (collected from the Netherlands n = 51 and the UK n = 60), alongside genetic (mcr-1–5) and phenotypic resistance against six other antimicrobial classes (aminoglycosides, cephalosporins, fluoroquinolones, penicillins, sulphonamides/trimethoprim, tetracyclines). Minimum inhibitory concentration (MIC) values were determined using a broth microdilution method (EUCAST guidelines), and phenotypic resistance was determined using disk diffusion. Colistin MIC values of APEC were significantly lower than those for commensals by 1 dilution (p < 0.0001, Anderson-Darling test), and differences in distributions were observed between countries. No isolate carried mcr-1–5. Three phenotypically resistant isolates were identified in 2/62 APEC and 1/111 commensal isolates. Gentamicin or gentamicin–ceftriaxone co-resistance was observed in two of these isolates. This study showed a low prevalence of phenotypic colistin resistance, with no apparent difference in colistin resistance between commensal E. coli strains and APEC strains.
