Abstract:
Objective To understand the molecular epidemiological characteristics of some rare serotype
Salmonella with pulsed field gel electrophoresis (PFGE) in Shanghai.
Methods 22 strains of
Salmonella including seven serotypes were isolated from different sources.PFGE were performed by genomic DNA digestion with Xba I restriction enzyme.
Results Significant difference were expressed between two strains of
Salmonella Lexington and two strains of
Salmonella Hvittingfoss in electrophoretogram map.Homology were expressed in electrophoretogram map for two strains of
Salmonella Montevideo, two trains of
Salmonella Langensalza, two strains of
Salmonella Uppsala, five strains of
Salmonella Schwarzenground and foure strains of
Salmonella Pomona.
Conclusion The epidemic strains of rare serotype
Salmonella and
Salmonella strains in food are expressed either as homology or non-homology in Shanghai.To make a comprehensive surveillance and real-time molecule typing analysis can predict the epidemic of rare serotype
Salmonella.
