为深入分析自美国沿海地区爆发或散发病例中分离的产毒素 O1群霍乱弧菌的流行病学,本文采用染色体 DNA 的限止性消化图型和 Southern 印迹技术,检测了1978～1981年从水和粪便中分离的10株产毒素非O1群霍乱弧菌和拟态弧菌,分析其相互关系及与该地区产毒素 O1群霍乱弧菌的关
In order to further analyze the epidemiology of Vibrio cholerae O1 group isolated from the outbreaks or sporadic cases in the coastal areas of the United States, the restriction digestion patterns of chromosomal DNA and Southern blotting were used to detect Vibrio cholerae Vibrio cholerae isolates from 1978 to 1981 Ten isolates of toxigenic V. cholerae and V. mimicus isolated from feces were analyzed and their correlations were analyzed and their relationships with V. cholerae producing toxins O1 in the area
