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.
本研究旨在检测弯曲菌属中大环内酯类耐药突变。在研究的 76 株菌中,33 株红霉素耐药菌株中有 30 株检测到 23S rRNA 基因 2059 位的点突变 A 到 G。在一个没有 23S rRNA 突变的耐药菌株中发现核糖体蛋白 L22 中的氨基酸插入。A2059G 突变是弯曲菌属大环内酯类耐药的主要原因。
