Popis: Purpose: To establish a new genotyping method for Vibrio cholerae and compare it with other methods. Materials and Methods: In the current study, a modified inter simple sequence repeat-polymerase chain reaction (MISSR-PCR) system was developed via several rounds of optimisation. Comparison study was then conducted between MISSR-PCR and three other methods, including enterobacterial repetitive intergenic consensus sequences-based PCR (ERIC-PCR), randomly amplified polymorphic DNA (RAPD) and 16S rRNA evolutionary clock, for the detection and genetic tracing of Vibrio cholerae isolated from seafood in China. Result: The results indicated that the MISSR-PCR system could generate the highest polymorphic fingerprinting map in a single round PCR and showed the best discriminatory ability for Vibrio cholerae genotyping by clearly separating toxigenic/nontoxigenic strains, local/foreign strains, and O1/O139/non-O1/non-O139 serogroup strains, comparing to ERIC-PCR, RAPD and 16S rRNA evolutionary clock. Moreover, the MISSR-PCR is superior to previously described traditional simple sequence repeat based PCR method on genotyping by more clearly separating different clusters. Conclusion: To the best of our knowledge, this is the first head-to-head comparison of four detection and genotyping methods for Vibrio cholerae The MISSR-PCR system established here could serve as a simple, quick, reliable and cost-effective tool for the genotyping and epidemiological study.
