Mechanisms of Antibiotic resistance in Salmonella typhi Posted on December 15, 2014by admin Authors Harriet Ugboko and Nandita De Abstract Salmonella typhi, the causative agent of typhoid fever, is a gram-negative, motile,rod shaped, facultative anaerobe. 15 0 obj Some, diseases, like TB, never easy to treat even with the few antibiotics that were, effective. These are production of drug-inactivating enzymes, modification of an existing target, acquisition of a target by-pass system, reduced cell permeability and drug removal from the cell. endobj Depending on the antimicrobial involved, the bacteria may use one or several of these resistance mechanisms. The following video explains the mechanisms that bacteria use to develop antibiotic resistance: Mechanisms of Antimicrobial Resistance. Would you expect to use amphotericin B against a bacterial infection? The development of resistance to antibiotics in bacteria often develop as a, resistance mechanisms, methods of detection and its controlling strategies on antibiotic resistance. Overview. Each of these mechanisms has been separately discussed in the following. enzyme production - It breaks down the lactam rings, there by inactivating the lactam antibiotics.
