Jeff Boyd’s Team Publishes Manuscript in Elife Showing That Oxygen Is a Signal for Staphylococcus aureus Biofilm Formation

The pathogenic bacterium Staphylococcus aureus lives on the human body. Generally this bacterium co-exists with us peacefully, but sometimes certain bacteria may enter the body and cause infections. Many of these infections are thought to occur when the bacteria become able to form complex communities called biofilms. Bacteria living in a biofilm cooperate and make lifestyle choices as a community, so in this way, they behave like a single organism containing many cells. Mashruwala et al. recently published a paper in eLife showing that, when oxygen levels are low, S. aureus cells lyse themselves to increase biofilm formation. These findings could result in novel treatment to infections caused by biofilm producing bacteria.
