Coexistence of optrA and fexA in Campylobacter.

ABSTRACT: Previous studies indicated that Campylobacter has developed several mechanisms that confer resistance to florfenicol, which is used in food animal production. This study describes the coexistence of optrA and fexA in Campylobacter jejuni and Campylobacter coli isolates from pigs and poultry. Moreover, whole-genome sequencing data showed that the two genes are located in various multidrug resistance genomic islands within different regions of the Campylobacter genomes. The emergence of optrA and fexA may support the spread of florfenicol-resistant Campylobacter strains of animal origin.IMPORTANCE Florfenicol is widely used for the treatment of respiratory infections and as a feed additive in food animal production. As a f
