Researchers at the University of California, Davis have developed a polypeptide that kills pathogenic bacteria.
Overuse of antibiotic treatments for bacterial infections can lead to bacterial resistance, making the antibiotics less effective. Antibiotics can also be harmful to the beneficial bacteria that assist in keeping their host healthy. There is a need for broad-spectrum antibiotics that have activity against harmful bacteria but not against beneficial organisms.
Researchers at the University of California, Davis have identified a single polypeptide that kills pathogenic bacteria. This peptide has been successfully spot tested using conventional minimum inhibitory concentration assays to be effective against several pathogenic bacteria including E. coli, K. pneumonia, and P. aeruginosa. The peptide may be used as a safe and effective antimicrobial agent in various applications towards preventing infections, blocking undesirable inoculations, and preventing the growth of undesirable bacteria in foods, beverages, consumer products, cosmetics, and health care products.
