Abstract: Distinguish of different pathogenic vibrio parahaemolyticus are normally based on tdh, trh and tlhgenes. In this research, the metabolic profiles were obtained by liquid chromatography(LC) and gas chromatography/mass spectrometry(GC-MS), and they were used for distinguishing different pathogenic vibrio parahaemolyticus. The results were compared with E. coli gene sequence between the repeat PCR(ERIC-PCR) and DNA repeats-PCR(REP-PCR). The similarity was calculated by NTsys2.10e software. The results showed that different pathogenic Vibrio parahaemolyticus could be distinguished by LC and GC/MS. Potential biomarkers of different pathogenic strains were found by GC-MS. Strain of tdh+, trh-, tlh+ have 3 kinds of potential biomarkers, strain of tdh-, trh+, tlh+ have 2 kinds of potential biomarkers, strain of tdh-, trh-, tlh+ have 3 kinds of potential biomarkers.
