美国疾病控制中心1969～1981年间收到61株生化反应类似的一组菌,不属于肠杆菌科中任何种。大多数分离自人类的伤口感染,先后被暂定名为Alma group 1,Enteric groupl和API group2。该菌的绝大多数生化反应和Enterobacter agglomerans相似,且半数以上菌株产生一种黄色色素。但该菌可借赖氨酸脱羧酶阳性和精氨酸双水解酶迟缓阳性和后者相区别。进一步研究发现,该菌和埃希氏属,尤其是最近提出的一个新种E.hermannii表型特征更为接近。DNA杂交研究表明,它应作肠杆菌科中一个独立的种。作者提出一个新的种名:Escherichia vulneris。以该菌典型菌株875-72(ATCC 33821)分别和15株E.vulneris行DNA杂交,60℃反应时为66～86%,75℃时为60～78%。该菌
The United States Centers for Disease Control received 61 strains of biochemical reactions from 1969 to 1981 that did not belong to any species of Enterobacteriaceae. The majority of wound infections isolated from humans have been tentatively named Alma group 1, Enteric groupl and API group2. The bacterium most biochemical reactions and Enterobacter agglomerans similar, and more than half of the strains produce a yellow pigment. However, this bacterium can be distinguished by a positive lysine decarboxylase-positive and arginine bianhydrolase-delayed positive and the latter. Further study found that the bacteria and the genus Escherichia, especially recently proposed a new species E.hermannii phenotype more closely. DNA hybridization studies have shown that it should be an independent species of Enterobacteriaceae. The authors propose a new species name: Escherichia vulneris. The typical strains of this strain 875-72 (ATCC 33821) were hybridized with 15 strains of E. vulneris DNA respectively, with 66 to 86% at 60 ° C and 60 to 78% at 75 ° C. The bacteria
