Analysis on characteristics of salmonella enteritidis from raw meat

Objective To assess the antibio tics susceptibility and genetical diversity of salmonella enteritidis isolated from raw and fresh meats.Methods Gene analysis by antibiotis susceptibility,ERIC-PCR techniquea and plasimid fingerprinting were put into practice for the detection of gene variation of 10 strains of salmnoella enteritidis.The similar ities between different strains were obtained by software NTSYS-PS210 for cluster analysis.Results 10 strains of salmonella enteritidis appear mult-i antibiotics resistance.These strains were subtyped into 3 groups A,B,C according to the electrophoresis profiles sinilarity 85% standard or above,including 2 strains,6 strains and 2 strains respectively.Conclusion These strains exist wide antibiotics resistance,10 strains of Salmonella enteritidis have lower genetical diverity.ERIC-PCR is a powerful tool for differentiating salmonella enteritdis and tracking the transmission of salmonella enteritidis in food.
