Drug inactivating enzymes
WebDrug resistance in Shigella spp. can result from many mechanisms, such as extrusion of drugs by active efflux pumps, decrease in cellular permeability, and overexpression of drug-modifying and -inactivating enzymes or target modification by mutation. 6,10, 11 The current study was done to review various antibiotic-resistance mechanisms of ... WebBesides biofilm-intrinsic resistance, other mechanisms of resistance (antibiotic target modification, drug-inactivating enzyme, efflux pumps, alteration of porin expression, and others) may allow pathogenic bacteria to be tolerant to all classes of conventionally available antimicrobials [13,16].

WebOct 17, 2014 · The presence of drug-metabolizing enzymes in the BBB is likely to have functional implications because local metabolism may inactivate drugs or may modify the drug’s ability to cross the BBB, thus modifying drug response and the risk of developing adverse drug reactions. WebThe authors further identified four acyltransferase genes ( C7H1G6, R5CY66, R6CZ24 and T5S060) in stool samples, which were significantly associated with steroid initiation, a marker of failing 5-ASA treatment in clinical practice. This was further replicated in another independent cohort of patients with IBD (SPARC IBD).
