We report armA in an Escherichia coli pig isolate from Spain. The resistance gene was borne by self-transferable IncN plasmid pMUR050. Molecular analysis of the plasmid and of the armA locus confirmed the spread of this resistance determinant.

The emergence of ESBL-producing S. enterica isolates among food animals is described for the first time in Spain, with those of the CTX-M group being the predominant ESBLs detected.

armA is present in human and animal isolates within a novel transposon composite. Further spread of armA between bacteria of diverse origin is to be expected.
