Abstract
IN recent years, many episomes other than the F factor of E. coli K12 have been discovered, such as the colicinogenic factors and the drug resistance transfer factors. Some of these seem to be related to F since they determine a pilus similar to the F pilus in serological properties and male specific phage sensitivity1. These F-like plasmids frequently inhibit their own transfer and of F when present in the same cell, but mutants have been obtained which do not produce the inhibiting substance and which allow transfer at a high rate1,2. One such mutant, R100-1, was used in the work to be described here.
