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.
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.
It’s a dog eat dog world, and bacteria have been living in it for a long time. It’s of no surprise that bacteria have a sophisticated arsenal to compete with each other for valuable resources in the environment.
