✦ Synopsis

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.
