A Cytolethal Distending Toxin Gene-Based Multiplex PCR Assay for Campylobacter jejuni, C. fetus, C. coli, C. upsaliensis, C. hyointestinalis, and C. lari

[摘要] References(10)In this study, we devised a multiplex PCR assay based on the gene of cytolethal distending toxin (cdt) B subunit to simultaneously detect and discriminate Campylobacter jejuni, C. fetus, C. coli, C. upsaliensis, C. hyointestinalis, and C. lari. Species-specific PCR products were successfully obtained from all 38 C. jejuni, 12 C. fetus, 39 C. coli, 22 C. upsaliensis, 24 C. hyointestinalis, and 7 C. lari strains tested. On the other hand, no specific PCR products were obtained from other campylobacters and bacterial species tested (41 strains in total). The proposed multiplex PCR assay is a valuable tool for detection and descrimination of 6 major Campylobacter species, that are associated with gastrointestinal diseases in humans.
