摘要: 基于tdh, trhtlh 3个基因区分了不同的致病性副溶血性弧菌. 采用液相色谱(LC)和气相色谱-质谱联用(GC-MS)技术获得不同的致病性副溶血性弧菌的代谢轮廓, 并将其用于区分不同的致病性副溶血性弧菌; 同时以肠杆菌基因间重复共有序列聚合酶链反应技术(ERIC-PCR)及DNA重复序列PCR技术(REP-PCR)为对照, 采用NTsys2.10e软件计算所得结果的相似系数, 并对气相色谱-质谱联用结果进行解析. 结果表明, 根据所得代谢轮廓可以很好地区分不同的致病性副溶血性弧菌; 对气相色谱-质谱联用分析结果解析发现了不同致病性菌株的潜在生物标志物: tdh+, trh-, tlh+菌株3种, tdh-, trh+, tlh+菌株2种, tdh-, trh-, tlh+菌株 3种.

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.
