The importance of using whole genome sequencing and extended spectrum beta-lactamase selective media when monitoring antimicrobial resistance.

ABSTRACT: To tackle the problem of antimicrobial resistance (AMR) surveillance programmes are in place within Europe applying phenotypic methods, but there are plans for implementing whole genome sequencing (WGS). We tested the benefits of WGS using Escherichia coli collected from pig surveillance performed between 2013 to 2017. WGS was performed on 498 E. coli producing ESBL and AmpC enzymes, recovered from pig caeca on MacConkey + cefotaxime (McC + CTX) agar, as recommended by the European Commission, or ESBL agar, used additionally by United Kingdom. Our results indicated WGS was extremely useful for monitoring trends for specific ESBL genes, as well as a plethora of AMR genotypes, helping to establish their prevalence and co-linkage to certain plasmids.
