Ribosomal Mutations as the Main Cause of Macrolide Resistance in Campylobacter jejuni and Campylobacter coli

Abstract

The aim of this study was to examine macrolide resistance mutations in Campylobacter species. In 76 strains studied, point mutation A to G at position 2059 of the 23S rRNA gene was detected in 30 of the 33 erythromycin-resistant strains. An amino acid insertion in the ribosomal protein L22 was found in one resistant strain without a 23S rRNA mutation. The A2059G mutation is the main cause of macrolide resistance in Campylobacter species.
