Abstract Thermophilic Campylobacter, particularly Campylobacter jejuni, is one of the major foodborne human pathogens of animal origin. Reliable and sensitive typing tools are required for understanding the epidemiology and ecology of this zoonotic bacteria agent. Currently, several molecular typing methods are available for differentiating Campylobacter strains, but each of them has limitations. Our previous study revealed that considerable sequence polymorphism exists in the cmp gene encoding the major outer membrane protein of Campylobacter and suggested that sequence variation of cmp may be utilized for discrimination of Campylobacter strains. In this study, we evaluated the feasibility of the cmp-based typing tool, using pulsed-field gel electrophoresis (PFGE) as the "gold" standard for comparison. The cmp alleles were sequenced from multiple Campylobacter strains, grouped, and compared with the PFGE profiles of these strains using Bionumerics. Results showed that 43 cmp sequence types and 43 PFGE types existed among the 60 Campylobacter isolates. Typeability of these strains is 100\% using either the cmp-based method or PFGE. The discrimination indices are 0.973 for the cmp-based method and 0.969 for PFGE, respectively. The cmp sequence types are 77.6\% congruent with the PFGE types. These results indicate that the cmp-based typing is a simple, yet highly discriminatory approach for molecular differentiation of C. jejuni strains.
