Quinolone and macrolide resistance of Campylobacter jejuni and Campylobacter coli mainly depend on a mutation in gyrA and in 23S rDNA, respectively. In order to detect quinolone and/or macrolide resistant C Jejuni and C coli strains, a macrolide and quinolone line probe assay (MQ-LiPA) was developed and 42 C jejuni and C coli strains were tested to evaluate the efficiency of the assay. Profiles of the mutations in 23S rDNA and in gyrA characterized by MQ-LiPA agreed with resistance to macrolides and quinolones. MQ-LiPA is a rapid and simple method for simultaneous detection of quinolone and macrolide resistance of C jejuni and C coli. We could also discriminate between C. jejuni and C. coli using probes for detection of gyrA mutations in MQ-LiPA. (C) 2003 Elsevier B.V. and the International Society of Chemotherapy.
