Bacteria flip an electric switch to worsen food poisoning

Salmonella bacteria flip an electric switch as they hitch a ride inside immune cells, causing the cells to migrate out of the gut toward other parts of the body, according to a new study publishing on April 9 in the open-access ...

Bile acid-triggered bacterial adaptation characterized

When bacteria enter the digestive tracts of their hosts, including humans, they encounter a highly acidic environment. Bacteria have evolved elegant mechanisms to survive and colonize this habitat, such as highly resistant ...

Gene expression study sheds new light on African Salmonella

Scientists at the University of Liverpool have taken another step forward in understanding the bacteria that are causing a devastating Salmonella epidemic currently killing around 400,000 people each year in sub-Saharan Africa.

Study pinpoints how Salmonella sneaks into plant roots

In recent years, contamination of salad vegetables by E. coli and salmonella bacteria—the most common causes of food poisoning—have led to large-scale recalls. Although most salmonella outbreaks are linked to contamination ...

Study shines new light on how Salmonella 'die' at low temperatures

The most economical way to kill bacteria that cause common food-borne illnesses—mostly caused by Salmonella enterica—is heat, but, the mechanisms that kill Salmonella at lower temperatures were not fully understood until ...

Bacteria can spread antibiotic resistance through soil

When most people think about bacterial antibiotic resistance, they think about it occurring in bacteria found in people or animals. But the environment surrounding us is a huge bacterial reservoir, and antibiotic resistance ...

Smartphone screen technology used to trick harmful bacteria

Conducting plastics found in smartphone screens can be used to trick the metabolism of pathogenic bacteria, report scientists at the Swedish Medical Nanoscience Center at Karolinska Institutet in the scientific journal npj ...

Inflammation awakens sleepers

The inflammatory response that is supposed to ward off pathogens that cause intestinal disease makes this even worse. This is because special viruses integrate their genome into Salmonella, which further strengthens the pathogen.

Detecting salmonella in pork meat twice as fast

A new method developed at the National Food Institute, Technical University of Denmark, halves the time it takes slaughterhouses to test for disease-causing salmonella in pork meat. The test can save the slaughterhouses money ...
