在生化上与霍乱弧菌流行株(01群霍乱弧菌株)相同,但对01群霍乱弧菌抗血清不凝集的弧菌,现在被称为非01群霍乱弧菌,而过去曾被称作非霍乱弧菌和不凝集弧菌。在孟加拉有过三次腹泻暴发与非01群霍乱感染有关,而且非01群霍乱弧菌感染曾引起重度霍乱样腹泻。1979年前,美国未见有非01群霍乱弧菌引起的暴发或集中的胃肠炎病例报告。 1979年11月间,有2例胃肠炎病人到佛罗里达的某甲医院就诊,从其大便标本中分离出了非01群霍乱弧菌。虽然该院于2年前就用TCBS培养基每年常规检查成年腹泻病人大便标本900份,但此次是首次分离出2株非01群霍乱弧菌。在另一次调查中,又鉴定出3例非01群霍乱弧菌胃肠炎。以上5例在发病前4天内均吃过生蚝,其临床和流行病学特点摘要见
Vibrio that is biochemically identical to the Vibrio cholerae group 01 (Vibrio cholerae group 01) but not agglutinated against the Vibrio cholerae 01 group, now referred to as Vibrio cholera non-O1 group, Vibrio cholerae and non-agglutination Vibrio. Three outbreaks of diarrhea in Bangladesh have been linked to non-01 cholera infections, and non-01 group Vibrio cholerae infections have caused severe cholera-like diarrhea. Before 1979, there were no reported cases of outbreaks or concentrated gastroenteritis caused by Vibrio cholera in the United States. In November 1979, two patients with gastroenteritis visited a hospital in Florida and isolated non-01 group V. cholerae from their stool specimens. Although the hospital routinely examined 900 stool samples of adult diarrhea patients with TCBS medium two years ago, it was the first time that two strains of V. cholerae 01 were isolated. In another survey, 3 non-01 group Vibrio cholerae gastroenteritis were identified. More than 5 cases of oysters were eaten within 4 days before the onset, the summary of its clinical and epidemiological characteristics
