By attaching fluorescent proteins to the genetic circuit responsible for B. subtilis's stress response, researchers can observe the cells' pulses as green flashes.
In response to a stressful environment like one lacking food, B. subtilis activates a large set of genes that help it respond to ... Read More
At this point, after finding microorganisms that don’t mind extreme temperatures, pressure, aridity and other hardships, we shouldn’t be surprised that bacteria’s dominion over the Earth extends to just about anywhere we look. A new expedition to the Earth’s crust has reached unprecedented depth... Read More
Serratia spp. are widely distributed in nature. Serratia marcescens is the most common Serratia sp. associated with human disease, followed by strains of the S. liquefaciens complex: S. liquefaciens, S. grimesii and S. proteamaculans. The clinical significance of these species is largely unknown... Read More

Helicobacter pylori (yellow), a common bacterium that lives in the stomach lining, increases the risk of stomach cancer (brown cells) and peptic ulcers. But over time H. pylori can reduce stomach acid and acid reflux, which may help fend off esophageal cancer. The microbe also appears to help pr... Read More
