Strains try to gain dominance by injecting competitor strains with toxins

The collisions promote mutations that may help bacteria adapt to stress

A growing body of evidence indicates that the trillions of microbes that live on and inside our bodies—what’s called our "microbiome"—affect our health.

Researchers have shown for the first time, in pregnant nonhuman primates, that Group B streptococcus bacteria employ a toxin to escape first-line immune defenses in the placenta and rapidly infect the amniotic cavity and developing fetus. 

Increasingly, people at risk for HIV infection are turning to preventive drug measures to help stave off the virus.

University of Washington researchers have discovered how a bacteria that causes a difficult-to-treat and often deadly respiratory infection attaches to cells in the airways.

A deceptively simple bacterium that survives in many types of environments has a sophisticated strategy to get rid of its competitors.  Reporting this week in the journal Cell, a University of Washington-led research team tells how

By studying the varied finches and tortoises of the Galapagos Islands in the 1800s, Charles Darwin realized that populations split by geographic boundaries, such as the sea, diverge as they experience different conditions.

A new, rapid method is helping detect how bacteria sense and respond to changes in their environment.  Bacterial can pick up external signals, which then relay to internal signaling pathways that direct their behavior.
