Uncovering novel phage defense systems through genomic island analysis in Streptococcus thermophilus

Audrey Leprince, Vincent Somerville, Justine Lefrançois…·Sylvain Moineau

This study identifies novel antiviral defense systems in Streptococcus thermophilus by analyzing genomic islands, revealing previously uncharacterized systems and highlighting their role as reservoirs of bacterial immunity.

Strengthening Phage Resistance of Streptococcus thermophilus by Leveraging Complementary Defense Systems

Audrey Leprince, Justine Lefrançois, Anne M. Millen…·Sylvain Moineau

This study identifies and validates 21 accessory defense systems in S. thermophilus, showing that some provide stronger phage resistance than CRISPR-Cas, especially when combined or expressed from plasmids.
