非OI群霍乱弧菌血清学分型系统的建立及初步应用

ESTABLISHMENT AND PRIMARY APPLICATION OF NON-OI VIBRIO CHOLERAE SEROTYPING SYSTEM (VBO)

本文报道了非OI群霍乱弧菌血清学分型系统的建立。应用这一分型系统对我国广东、福建及河南三省分离的549株菌进行血清学定型。菌株可分为55型。其中的优势型为VBO2、7及9。菌型的分布与分离地区有关。并发现有19个菌型是日本及美国分型系统所未包括的新菌型。血清的分型率为83.79%。对患者分离的菌株有较高的分型率。

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.
