Determination of Inherited Traits of H. Influenzae by Desoxyribonucleic Acid Fractions Isolated from Type-specific Cells


Change of non-typable (R) strains of H. influenzae into the specific type of origin or new types (S) has been effected in vitro in a predictable fashion within a single 24 hour growth period, by a desoxyribonucleic acid-containing fraction isolated from type-specific cells of the type desired. Only a small proportion of the population of R cells are… (More)
