迄今为止描述的所有 R 因子均可传播至大肠杆菌。F 样 R 因子可传播至变形杆菌属，但不能传播至假单胞菌科。在 fi−R 因子中，I 样质粒不可转移至变形杆菌，尽管它们介导接合，允许将其他质粒转移至该组。它们不能传播给假单胞菌科。 P 组质粒可传播至两个类群。 N组和W组的质粒可传播至变形杆菌（由于缺乏合适的标记，未测试至假单胞菌的转移）。
All R factors so far described can be transmitted toEscherichia coli.F-like R factors are transmissible to the Proteus group but not to the Pseudomonadaceae. Among,fi−R factors, I-like plasmids are not transferable to Proteus although they mediate conjugation, allowing transfer of other plasmids to this group. They are not transmissible to the Pseudomonadaceae. P-group plasmids are transmissible to both taxa. Plasmids of groups N and W are transmissible to Proteus (transfer to Pseudomonas was not tested because of lack of suitable markers).
