中文摘要:
      为了研究牡蛎养殖过程中副溶血弧菌与水质因子之间的关系,2009年3月到11月从广东阳西某牡蛎养殖场采集牡蛎样品检测其副溶血弧菌的感染情况,并检测水体温度、盐度、pH和溶解氧。实验结果表明:副溶血弧菌总量的检出率为94.38%。水温和副溶血弧菌总量呈正相关,盐度和副溶血弧菌总量呈负相关,pH和溶解氧与副溶血弧菌总量的相关性不明显。对水温和盐度与副溶血弧菌总量的对数进行回归分析,水温和副溶血弧菌浓度的拟合回归方程为LgVP=0.093T-0.685(R2=0.336);盐度和副溶血弧菌浓度的拟合回归方程为LgVP=1.199+0.116S-0.004S2(R2=0.217);水温和盐度对副溶血弧菌浓度的拟合回归方程为LgVP=-1.941+0.116T+0.058S-0.001S2(R2=0.414)。研究结果可为牡蛎养殖过程中副溶血弧菌的风险分析提供参考依据。
英文摘要:
      Vibrio parahaemolyticus(VP) is a pathogen of bacterial food poisoning associated with shellfish.VP,which is detected both in human and fish,has even higher concentrations in oysters and other filter-feeding shellfish.In order to study the relationship of VP densities versus water quality factor including water salinity,temperature,pH and dissolved oxygen in the course of oyster culture,we detected total VP densities in the oyster and water quality factor at the oyster farm in Yangxi,Guangdong from March to November in 2009.The results showed that the detection ratio of total VP in oysters was 94.38%.The water temperature was correlated positively with total VP in oysters,but the salinity was correlated negatively with total VP in oysters.The dissolved oxygen and pH didn’t show correlation with total VP in oysters.Based on the regression analysis,a quadratic relationship for VP densities versus water temperature and salinity was found.The regression equation of VP densities versus water temperature was:LgVP=0.093T-0.685(R2=0.336);The regression equation of VP densities versus salinity was:LgVP=1.199+0.116S-0.004S2(R2=0.217);The best fit regression equation of VP densities versus water temperature and salinity was LgVP=-1.941+0.116T+0.058S-0.001S2>(R2=0.414).The results of this paper may provide some reference data for the risk analysis of VP during oyster culture.
