Breakthrough in infection research: New substance C26 fights salmonella!

A research team from the University of Tübingen, in collaboration with the German Center for Infection Research, has identified a promising substance that has the potential to stop salmonella infections at an early stage. The substance, known as C26, acts as a “pathoblocker” and thus offers new perspectives for combating these dangerous bacteria. Salmonella is notorious for causing severe gastrointestinal inflammation by injecting effector proteins into the cells of the gastrointestinal tract, often via contaminated food. uni-tuebingen.de reports of the discovery published on April 14, 2025.

C26 has the ability to intervene preventively before Salmonella can penetrate the tissue. In doing so, it specifically disrupts the signaling chains that are responsible for the infection process. Particularly noteworthy is the effect on the HilD regulator, which plays a central role in the penetration of Salmonella into the host cells. C26 fits into the specific binding site of this regulator and blocks its function, so that the bacteria are no longer able to introduce their harmful effector proteins. phys.org lifts highlights the importance of this discovery for future therapeutic approaches.

Urgent need for new treatment methods

The researchers emphasize the urgency of innovative treatment options as Salmonella has developed resistance to many common antibiotics. This development is forcing doctors to seek new strategies to combat the pathogenicity of these bacteria. C26 could serve as a new therapeutic option, both for humans and animals. The approach could be particularly applicable in animal husbandry, as salmonella infections are widespread in poultry production.

The results of the research were published in the journal Science Advances and demonstrate the potential of C26 without negatively affecting the beneficial microbes in the human gut. This represents significant progress, particularly at a time when antibiotic resistance is a growing global problem. How out pmc.ncbi.nlm.nih.gov According to reports, resistance rates among Salmonella strains have increased by 20-30% in recent decades, further reinforcing the need for alternative treatment options.

The way forward for pathoblockers

Research shows that C26 not only works against Salmonella, but also has the potential to be used alongside other strategies, such as probiotics or vaccines. The development of antimicrobial peptides and bacteriophages is also considered complementary. Such integrative approaches are crucial to overcoming the challenges associated with combating Salmonella and its resistance.

C26 represents an important step on the path to new therapeutics. Further development of this type of pathoblockers could make a significant contribution to reducing infections in humans and animals and thus play an important role in global health management. The next steps will be critical to realize the full potential of this discovery and revolutionize the fight against Salmonella infections.
