The incompatibility reactions of four new R factors have been determined against reference plasmids of the compatibility groups FI, FII, FIII, FIV, FV, FVI and various not F-like groups. Two R factors have been found to belong to group FII, while one of the two other plasmids was incompatible with representatives of the FII and FI groups. The last R factor was incompatible with plasmids of FII and P groups. It seems, therefore, that R factors with incompatibility for more than one group of plasmids occur frequently in nature.
已针对相容性群FI、FII、FIII、FIV、FV、FVI的参考质粒以及各种非F类群，测定了四种新R因子的不相容反应。已发现两种R因子属于FII群，而另外两种质粒中的一种与FII群和FI群的代表不相容。最后一种R因子与FII群和P群的质粒不相容。因此，似乎在自然界中，对不止一组质粒具有不相容性的R因子很常见。
