OBJECTIVE
To study the distribution of non-O1 Vibrio cholerae pigmentogens in water and its biological characteristics and pathogenicity.
METHODS
Samples were collected from local source of drinking water and cultured for pathogenic V. cholerae. Non-O1 V. cholerae was isolated and identified with nutrient agar slant instead of KIA.
RESULTS
Ten strains of V. cholerae producing pigment with negative Gram's stain were detected in the source water in Lu' an Prefecture, Anhui Province during 1994 to 1997, which could all met the definition of non-O1 V. cholerae in morphology, cultural characteristics, biochemistry and serology, with systematic identification. Animal experiments showed that it had strong virulence.
CONCLUSION
These strains of V. cholerae cultured in basic cholate agar, nutrient agar slant and blood agar could produce brown pigment, so it was called non-O1 V. cholerae pigmentogens.
目的
研究非O1群霍乱弧菌产色素株在水中的分布及其生物学特性与致病性。
方法
从当地饮用水源采集样本，培养致病性霍乱弧菌。用营养琼脂斜面而非KIA分离并鉴定非O1群霍乱弧菌。
结果
1994年至1997年期间，在安徽省六安市的水源水中检测到10株革兰氏染色阴性的产色素霍乱弧菌，经系统鉴定，其在形态、培养特性、生化及血清学方面均符合非O1群霍乱弧菌的定义。动物实验表明其具有较强毒力。
结论
这些在碱性胆盐琼脂、营养琼脂斜面及血琼脂上培养的霍乱弧菌菌株可产生褐色色素，故称为非O1群霍乱弧菌产色素株。
