title: Transduction of rifampin resistance in group A streptococci.
abstract: Rifampin-resistant strains of group A streptococci were isolated as spontaneous mutants. Transduction analyses employing phage A25 showed the rifampin marker to be transferred with high frequency. The mutations conferring resistance to rifampin and streptomycin are not co-transducible.
