Huge Discovery: Bacterium that “Eats” Plastic Waste

We Now Know HOW Antibiotics Kill off Good Bacteria in the Gut

A single course of antibiotics can cause Clostridium difficile, or C. diff – a bacterium that can lead to a condition known as Clostridium difficile colitis – to flourish in the gut, according to researchers at North Carolina State University.
The discovery was made during experiments with mice. The scientists say the antibiotics were found to kill off bacteria responsible for altering bile acid.

Scientists: Lack of Good Gut Bacteria Could Be Giving You Cancer

For many years now it has been widely known that smoking, certain dietary factors, obesity, and many other factors are major contributors to cancer incidence. However, a growing body of research has shown that specific changes in the intestinal flora, or dysbiosis, can be found in the stools or on the colonic walls of patients with diseases such as colon cancer.
