Foodborne Pathogens and Disease




In Campylobacter spp., resistance to erythromycin and other macrolides has typically implicated ribosomal mutations, especially substitutions in the 23S rRNA genes. However, in 2014, the macrolide resistance gene erm(B) was reported for the first time in Campylobacter and shown to be harbored by a multidrug resistance island in the chromosome of the swine-derived strain Campylobacter coli ZC113. erm(B)-positive C. coli and Campylobacter jejuni strains from the food supply have been mostly reported from China. However, erm(B)-positive C. coli isolates were also detected recently in fecal samples from turkeys in Spain. To determine whether erm(B) may be harbored by erythromycin-resistant Campylobacter from commercial turkey production in eastern North Carolina, a major turkey-growing region in the United States, we investigated a panel of 178 erythromycin-resistant isolates (174 C. coli, 4 C. jejuni) using PCR with erm(B)-specific primers. None of the isolates were PCR-positive for erm(B) and sequence analysis of a subset of these erythromycin-resistant isolates revealed that all harbored A2075G substitutions in the 23S rRNA genes. Data fail to provide evidence for infiltration of erm(B) into erythromycin-resistant Campylobacter from commercial turkey production in this region and suggest the need for continuing surveillance.
