Scientists have found a new type of antibiotic with the function of treating multiple resistant bacteria

Recently, researchers from the University of Illinois in Chicago and the French company nosopharm (http:// have found a new class of antibiotics This kind of new antibiotics has the function of treating many kinds of resistant bacteria The compound, called odilrhabdins (ODL), was isolated from a symbiotic bacterium living in the soil and feeding on insects Such symbionts can help nematodes kill insects and inhibit the growth of other competitive bacteria by secreting antibiotics The researchers from nosopharm screened 80 different strains, and compared their antibacterial ability Then they isolated the above active substances, and studied their chemical structure, so as to design more effective derivatives The researchers found that ODL can interact with ribosomes, the key element responsible for protein synthesis in bacteria (http:// Unlike previous antibiotics, although ODL can target ribosomes, the binding site of ODL to ribosomes is not present in previous antibiotics, the researchers said However, the researchers hope to be able to develop new antibiotics based on ODL, so as to help the treatment of various bacterial infectious diseases
