WebIn the CVMP/SAGAM opinion, neomycin and kanamycin are valuable antibiotics for treatment of, e.g. E. coli associated enteric diseases in food-producing animals. The extent of use of neomycin/kanamycin to treat that condition will vary between countries, depending on what is available and on the occurrence of resistance to alternative ... Kanamycin works by interfering with protein synthesis. It binds to the 30S subunit of the bacterial ribosome. This results in incorrect alignment with the mRNA and eventually leads to a misread that causes the wrong amino acid to be placed into the peptide. This leads to nonfunctional peptide chains.
