CHARLOTTESVILLE, Va. (WVIR) - Researchers at the University of Virginia Health System have made a new discovery about E. coli.

Scientists have revealed how the pathogen seeks out oxygen-free crevices of your colon, which can lead to the worst possible infections. By knowing this information, researchers have created a molecule to discover E. coli living in low-oxygen environments of the large intestine.

"We think this discovery is important because if we can block pathogenic E. coli from knowing where it is in its body then it won't make these toxins that make us sick, and it will just pass through," said Melissa Kendall, UVA Health System.

Experts remind people to make sure they are careful with raw meat, unpasteurized dairy products, and unwashed produce - those are the most common sources E. coli.
