Streptococcus thermophilus is a common dairy starter for which very few genetic exchange systems have been described. Here we report plasmid transduction by phi 17 alpha and phi 56 alpha, two virulent phages of industrial yogurt starter strains. Several replicons could be transduced, independently of their size, with efficiencies which are high enough to allow gene transfer from a transformable intermediary strain of S. thermophilus to other hosts of the bacteriophages studied.
嗜热链球菌是一种常见的用于乳制品发酵的菌种，针对它的遗传交换系统鲜有报道。在此我们报告了由phi 17 alpha和phi 56 alpha介导的质粒转导，这两种烈性噬菌体来自工业酸奶发酵剂菌株。几个复制子能够被转导，与它们的大小无关，转导效率高到足以使基因从嗜热链球菌的一个可转化中间菌株转移到所研究噬菌体的其他宿主中。
