Abstract
The ability to produce diplococcin (Dip+) was transferred by conjugation from Streptococcus cremoris 346 to two plasmid-free S. cremoris recipients at a high frequency (10(-1) per donor). Dip+ transconjugants from each mating gained a 54-megadalton plasmid. Spontaneous loss of this plasmid restored the Dip- phenotype.
