Research shows how pathogenic bacteria hide inside host cells

A new study into Staphylococcus aureus, the bacterium which is responsible for severe chronic infections worldwide, reveals how bacteria have developed a strategy of hiding within host cells to escape the immune system as well as many antibacterial treatments. The research, published by EMBO Molecular Medicine, demonstrates how 'phenotype switching' enables bacteria to adapt to their environmental conditions, lie dormant inside host cells and become a reservoir for relapsing infections.
