Genome-wide analysis of fitness determinants of Staphylococcus aureus during growth in milk

Marita Torrissen Mårli, Anne Olsdatter Ohren Nordraak, Vincent de Bakker…·Morten Kjos

This study identifies 282 milk-essential genes in Staphylococcus aureus using CRISPRi-seq, highlighting purine biosynthesis, folate cycle, and metal acquisition as critical for growth in milk.

Self-immunity towards a novel competence-induced streptococcal murein hydrolase is mediated by a Fem-transferase-like protein

Marita Torrissen Mårli, Magnus Ø. Arntzen, Jennie Ann Allred…·Daniel Straume

The paper identifies ScrM, a competence-induced murein hydrolase in Streptococcus dysgalactiae, and shows that ScrI, a Fem-transferase-like protein, mediates self-immunity by modifying peptiglycan to prevent ScrM binding.
