Incompatibility between R factors has been reported by several authors, and four incompatibility groups have already been described by Datta and Hedges among Rfi(-) factors. The stability of 12 plasmids in pairs was studied after 116 crosses, and five new groups were found, designated 5, 6, 7, 8, and 9. Each plasmid studied belongs to one single group. Incompatibility between plasmids in pairs is a clear-cut phenomenon, is easy to observe, and can provide a reliable method for recognizing and classifying resistance factors, and for tracing their spread among bacterial species.
几位作者报道了R因子之间的不相容性,达塔和赫奇斯已经在Rfi(-)因子中描述了四个不相容组。在116次杂交后研究了12种质粒对的稳定性,发现了五个新的组,命名为5、6、7、8和9。所研究的每种质粒都属于一个单独的组。质粒对之间的不相容性是一种明确的现象,易于观察,并且可以为识别和分类抗性因子以及追踪它们在细菌物种中的传播提供一种可靠的方法。
