title: Bacteriocin production by group a streptococcal L-forms.
abstract: L-forms induced from a bacteriocin-producing strain of group A streptococcus retained both the ability to produce the streptococcin and producer strain immunity to the homologous bacteriocin. L-forms of a spontaneously cured (bacteriocin negative) derivative of this same strain failed to produce streptococcin but were sensitive to its action.
