Escherichia coli (E. coli) is a common bacterium that lives in the intestines of animals and humans, and it is often used to ...

The widespread use of antibiotics has long been implicated in the rise of drug-resistant infections. Now, scientists wonder whether unrelated drugs play a role too. In a new study, antidepressants ...

She has studied how the pathogenic bacterium Escherichia coli reacts when exposed to small, non-fatal amounts of the ...

Most urinary tract infections (UTIs) are caused by the E. coli bacteria, which are treated with antibiotics. But some strains may be resistant to common antibiotic types. For the most part ...

Antibiotics are supposed to wipe out bacteria, yet the drugs can sometimes hand microbes an unexpected advantage.

The subtle changes might be enough to alter the binding site of drug targets and constitute a possible new mechanism of antibiotic resistance. Escherichia coli is a common bacterium which is often ...

From 185 fecal samples, the scientists isolated a total of 135 strains of E. coli and exposed the microbes to 16 different types of broad-spectrum antibiotics, drugs that can kill or inhibit a ...

But in an unusual twist, the loss of function may have repurposed this set of genes to create conditions that trap antibiotics in E. coli's cell membrane, preventing them from entering the bacteria.

coli bacteria react when exposed to the antibiotic Ciprofloxacin. When E. coli detects damage to its genetic material, it sends out an SOS signal that alters activity inside the cells.
