  • Publication number: 20070191291
    Abstract: The use of the combination of N-acetyl-D-glucosamine and antibiotics for the preparation of antibacterial drugs is disclosed. In the therapies of infections with antibiotics, the pathogens may be changed into slender shaped forms called cryptic growth cells (CGCs), CGCs can colonize and thereby physiological drug resistance arises. In the meantime, normal bacteria colonies in the body may be also changed into CGCs upon administration of antibiotics. These changes result in complications after the therapies, such as disorder of bacteria colonies in the body, disorder of GI functions and other chronic diseases. The combination of antibiotics and N-acetyl-D-aminoglycosamine can prevent of CGC, and the complications after antibiotics therapy.
