Scientists have discovered a natural compound that targets dangerous C. difficile bacteria without wiping out the gut’s beneficial microbes. Successful early tests suggest it could lead to a gentler, more effective treatment for stubborn intestinal infections that frequently return.
A dangerous intestinal infection may soon have a more targeted treatment option. Scientists have identified a natural compound that can kill the bacteria responsible for severe gut infections while leaving much of the beneficial gut microbiome unharmed.
The bacterium Clostridioides difficile (C. difficile) is naturally found in the intestines of many people and generally causes no problems when present in small amounts. However, antibiotics that target a wide range of bacteria can upset the delicate balance of microorganisms in the gut. This disruption allows C. difficile to multiply rapidly, potentially causing severe intestinal inflammation that can become chronic.
C. difficile infections (CDI) are among the leading causes of diarrhea associated with antibiotic treatment. The bacteria produce toxins that can trigger dangerous and sometimes life-threatening inflammation in the intestines. Because these infections frequently return after treatment, scientists are searching for more effective ways to eliminate the pathogen without causing additional damage to the gut microbiome.
A team led by Prof. Rolf Müller, department head and scientific director at HIPS, has now identified a promising drug candidate that specifically targets C. difficile while preserving much of the gut’s beneficial microbial community. HIPS is a site of the Helmholtz Centre for Infection Research (HZI) that operates in collaboration with Saarland University.
