Infections with Salmonella bacteria, often caused by eating or handling undercooked meat or eggs, affect about 100 million people a year worldwide. The suffering the infection causes—abdominal cramps, fever and diarrhea—is ...

How nature engineered the original rotary motor

The bacterial flagellum is one of nature's smallest motors, rotating at up to 60,000 revolutions per minute. To function properly and propel the bacterium, the flagellum requires all of its components to fit together to exacting ...

Epidemic outbreaks caused by environment, not evolution

Researchers have traced genetic changes in a bacterial pathogen over 450 years, and claim that epidemics of bacterial disease in human history may be caused by chance environmental changes rather than genetic mutations.

New study sheds light on how Salmonella spreads in the body

Findings of Cambridge scientists, published today in the journal PLoS Pathogens, show a new mechanism used by bacteria to spread in the body with the potential to identify targets to prevent the dissemination of the infection ...
