Molecular epidemiology of blaCTX-M-1 plasmids in non-broilers Escherichia coli isolates from UK, Sweden and France

Genes encoding Extended-Spectrum Beta-Lactamases of the CTX-M group are highly prevalent, and
plasmids play a key role in their spread. The blaCTX-M-1 IncI1/ST3 plasmid is
dominant in various animals in France. However, the situation in other countries
is not known. The epidemiology of the blaCTX-M-1 gene in Europe may differ
between broilers and non-broiler animals such as cattle, horses and pets, as a
consequence of major international exchanges (broilers) versus in-house
antimicrobial selection (other animals). This project intents to highlight this issue
in exploring the CTX-M-1 plasmid reservoir in UK, Sweden and France outside the
broiler production.
