Covert fi− R Factors in fi− R+ Strains of Bacteria

RESUMO
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.
