We have isolated a strain of Escherichia coli from chicken caeca which produces two E colicins and colicin M. This strain has seven plasmids, five of which have been transferred to E. coli K12. Two E. coli K12 derivatives which produce the two E colicins separately have been tested against seven standard E colicin producing strains which define seven different immunity groups. Our results indicate that these new E colicins define two further immunity groups, E8 and E9.
我们从鸡盲肠中分离出了一株大肠杆菌，它能产生两种大肠杆菌素和大肠杆菌素M。该菌株有7个质粒，其中5个已被转移到大肠杆菌K12中。已经分别测试了两种能单独产生这两种大肠杆菌素的大肠杆菌K12衍生物，以对抗7种标准的产大肠杆菌素菌株，这些菌株定义了7个不同的免疫群。我们的结果表明，这些新的大肠杆菌素定义了另外两个免疫群，即E8和E9。
