Pathogenic Vibrio parahaemolyticus (Vp) (tdh(+)/trh(+)) represent a small percentage of environmental Vp populations, and very little is known about this subpopulation. Repetitive extragenic palindromic PCR and multilocus sequence analysis revealed heterogeneity among 41 Vp containing thermostable direct hemolysin (tdh) and tdh-related hemolysin (trh) that were isolated from Mississippi coastal environments from October 2006 to April 2007. There was no source-specific sequestering in oysters, water, or sediment.
致病性副溶血性弧菌（tdh(+)/trh(+)）在环境副溶血性弧菌群体中占比很小，人们对这一亚群知之甚少。重复外显子回文PCR和多位点序列分析揭示了2006年10月至2007年4月从密西西比沿海环境分离出的41株含有耐热直接溶血素（tdh）和tdh相关溶血素（trh）的副溶血性弧菌之间的异质性。在牡蛎、水或沉积物中不存在特定来源的隔离现象。
