The incompatibility reactions of a group of 90 R plasmids, isolated from the fecal Escherichia coli of calves, pigs, and chickens, have been determined against reference plasmids of the incompatibility groups F(11), I, N, P, and W. Twenty plasmids belonged to incompatibility groups F(11), I, N, or P. Forty-nine plasmids were compatible with all of the five reference plasmids. Eight plasmids exhibited marked incompatibility with representatives of two or more of the above groups, whereas two strains showed incompatibility reactions consistent with the coexistence of two compatible plasmids. In addition, 19 plasmids remain untyped because they showed intermediate reactions with one or more reference plasmids.
从犊牛、猪和鸡的粪便大肠杆菌中分离出一组90个R质粒,并针对不相容群F(11)、I、N、P和W的参考质粒测定了它们的不相容反应。20个质粒属于不相容群F(11)、I、N或P。49个质粒与所有5种参考质粒相容。8个质粒与上述两个或更多组的代表表现出明显的不相容性,而两个菌株显示出与两个相容质粒共存一致的不相容反应。此外,19个质粒仍未分型,因为它们与一种或多种参考质粒表现出中间反应。
