Study on 14 Vibrio cholerae O139 strains by PFGE and ribotyping in Chongming, Shanghai

  • Objective To understand the genotypes of 14 strains of Vibrio cholerae O139 isolated in Chongming in 2005. Methods Pulsed-field gel electrophoresis (PFGE) and ribotyping were conducted to analyze the Vibrio cholerae strains. Results Ribotyping indicated that the genotypes of all the O139 strains were same; but PFGE indicated that 10 of 14 strains of Vibrio cholerae O139 belonged to same type, the other 4 strains were highly homologous. Conclusion The genotypes of Vibrio cholerae O139 circulating in Chongming in Shanghai in 2005 were similarly.
