Abstract

SUMMARY

Two strains of K12 carried R factors associated with the hsII host specificity determinants although they were apparently , while all other R factors carrying this host specificity have been found to be When these two strains were used as donors of drug resistance, separation of two R factors from each strain was observed. The separated R factors were tested for character, and it was found that in both cases the original strains carried an and an R factor, and it was the R factor which carried the hsII determinants.
