Determinants of streptococcin A-FF22 (SA) production and host cell immunity have been transduced to three serologically distinct Group A streptococci. Streptomycin resistance markers were not cotransducible with bacteriocin determinants. SA+ transductants of strains unrelated to the parent SA+ strain were unstable but SA+ transductants of a spontaneous SA- derivative of the parent appeared to be stable.
链球菌素A-FF22(SA)产生的决定因素和宿主细胞免疫已被转导至三种血清学上不同的A组链球菌。链霉素抗性标记不能与细菌素决定因素共转导。与亲本SA+菌株无关的菌株的SA+转导子不稳定,但亲本自发SA-衍生物的SA+转导子似乎是稳定的。
