Abstract

The presence of an fi(-) sex factor can be detected by propagation of the I-specific phage If1. By use of this method of detection, a high proportion of strains with fi(+) R factors were shown also to carry an fi(-) factor which was frequently a second R factor. In some doubly R(+) strains, the fi(+) and the fi(-) factor were observed to be transferred independently at conjugation.

摘要

通过I特异性噬菌体If1的增殖可以检测到fi(-)性因子的存在。利用这种检测方法表明,高比例的带有fi(+)R因子的菌株也携带一个fi(-)因子,该因子通常是第二个R因子。在一些双重R(+)菌株中,观察到fi(+)和fi(-)因子在接合时独立转移。
