The distribution and virulence of Vibrio cholerae serogroups other than O1 and O139 in India before, during and after the advent of O139 serogroup was investigated. A total of 68 strains belonging to 31 different 'O' serogroups were identified during the study period. With the exception of O53, there was no spatial or temporal clustering of any particular non-O1 non-O139 serogroup at any given place. Two of the 68 strains examined produced cholera toxin (CT) which could only be partially absorbed with anti-CT immunoglobulin G. Tissue culture assay revealed that some of the non-O1 non-O139 strains produced factors which evoked either a cell rounding or cell elongation response depending upon the medium used. This study indicates that serogroups other than O1 and O139 should also be continuously monitored.
在O139血清群出现之前、期间和之后,对印度除O1和O139之外的其他霍乱弧菌血清群的分布和毒力进行了调查。在研究期间共鉴定出属于31个不同“O”血清群的68株菌株。除O53外,在任何特定地点,任何特定的非O1非O139血清群均无空间或时间聚集现象。所检测的68株菌株中有两株产生霍乱毒素(CT),该毒素只能被抗CT免疫球蛋白G部分吸收。组织培养试验表明,一些非O1非O139菌株产生的因子会根据所用培养基引起细胞变圆或细胞伸长反应。本研究表明,除O1和O139之外的血清群也应持续监测。
