The markers coding for serotype B penicillinase (PcB) in wild type strains of group II of S. aureus behaved as chromosomal characters in 6 out of 7 cases. The restriction deficient mutants also to some strains of group I. No extrachromosomal DNA could be detected in the transductants. The low frequency of transduction of chromosomal markers as well as the high restriction barrier seem to limit the spread of these markers outside group II.
金黄色葡萄球菌II组野生型菌株中编码B型青霉素酶（PcB）的标记在7例中有6例表现为染色体特征。限制缺陷型突变体在I组的一些菌株中也存在。在转导子中未检测到染色体外DNA。染色体标记的低转导频率以及高限制屏障似乎限制了这些标记在II组之外的传播。
