Establishment and primary application of non-OI Vibrio cholerae serotyping system (VBO)
非OI群霍乱弧菌血清学分型系统的建立及初步应用

A serotyping system for Vibrio cholerae non-OI was reported in this paper. With this typing system, 549 strains isolated from Guangdong province, Fujian province and Henan province were typed. The 55 serotypes were found in these strains. Among this, the dominant types were VBO 2, 7 and 9. The distribution of serotypes related with the different region. In our experiment, 19 serotypes were new types, different from sakazaki or smith strains. 83.79% tested strains can be typed with this VBO serotyping system.
