A toxin secreted by cholera bacteria can inhibit the growth of colorectal cancer without causing any measurable damage to the body. This is shown by a new study by researchers at Umeå University, ...

A bacterial toxin called colibactin, produced by certain strains of E. coli, appears to alter gut DNA in a way that prompts colon cancer, researchers report in the journal Nature. Photo by ...

Cholera remains a major global public health challenge, with an estimated 1.3 to 4 million cases and tens of thousands of deaths reported worldwide each year. Caused by the bacterium Vibrio cholerae, ...

Colorectal cancer has increased significantly over the past 20 years among adults under 50. Now scientists may have identified a potential factor in the rise: a toxin called colibactin. Exposure to ...

Baylor University researchers have developed a novel approach to fight colorectal cancer, using modified bacteria as a ...

Colibactin is a powerful toxin produced by Escherichia coli and other bacteria living in the human gut. This highly unstable bacterial product causes mutations in DNA that have been linked to ...

Gram-negative bacteria deploy a range of protein toxins as mediators of inter-bacterial competition and pathogenicity. Among these, colicins comprise a class of ribosomally synthesised bacteriocins ...

Researchers developed a technique that attaches a cancer-killing toxin to modified bacteria capable of entering tumor cells.

Ulcerative colitis (UC) is one of the most common inflammatory bowel diseases, a lifelong condition that can cause chronic inflammation and ulcers in the lining of the large intestine. This can lead ...

Colon cancer cases have been increasing among younger adults, and now researchers think they've identified a potential culprit. A bacterial toxin called colibactin, produced by certain strains of E.
