• [14] The global problem of advancing antimicrobial resistance has led to a renewed interest in its use more recently. (mdwiki.org)
  • Identification is critically important as it can reduce the cost and toxicity of the antibiotic therapy and also reduce the possibility of the emergence of antimicrobial resistance. (mdwiki.org)
  • However, the effectiveness and easy access to antibiotics have also led to their overuse [8] and some bacteria have evolved resistance to them. (mdwiki.org)
  • Development of bacterial resistance under therapy is a frequent occurrence and makes fosfomycin unsuitable for sustained therapy of severe infections. (mdwiki.org)
  • On the other hand, clinical isolates producing IMP-1 type metallo-β-lactamase, which show resistance to carbapenems and cephamycins as well as various expanded-spectrum cephalosporins, have been identified in Japan ( 15 ) , and the proliferation of these strains has become a clinical concern ( 16 ) . (cdc.gov)
  • Activity against extended-spectrum β-lactamase -producing pathogens, notably ESBL-producing E. coli , is good to excellent, because the drug is not affected by cross-resistance issues. (mdwiki.org)

  • In current study, additionally to their pharmacokinetics and pharmacodynamics, we have presented current knowledge about the genes and two-component systems that may cause such resistance to polymyxin and colistin. (modernmedlab.com)

  • [6] Resistance to colistin is beginning to appear as of 2017. (mdwiki.org)
  • For example, they have an internal mechanism of changing their structure so the antibiotic no longer works, they develop ways to inactivate or neutralize the antibiotic. (emedexpert.com)
  • Also bacteria can transfer the genes coding for antibiotic resistance between them, making it possible for bacteria never exposed to an antibiotic to acquire resistance. (emedexpert.com)
  • The problem of antibiotic resistance becomes more serious when antibiotics are used to treat disorders for which they are ineffective. (emedexpert.com)
  • However, resistance to this antibiotic has been reported and is appearing day by day. (modernmedlab.com)
  • Not much information is available on the exact mechanisms of resistance to this antibiotic. (modernmedlab.com)

  • [ 29-31 ] Intrinsic resistance to β-lactams is exemplified by a chromosomally encoded AmpC cephalosporinase, to which cefepime and carbapenems appear to be stable. (medscape.com)
  • [ 39 , 40 ] Synergy between acquired oxacillinases and the AdeABC pump has been reported and implicated in higher levels of resistance to β-lactams, including carbapenems. (medscape.com)
  • Beta-lactamases are enzymes ( EC 3.5.2.6 ) produced by some bacteria and are responsible for their resistance to beta-lactam antibiotics like penicillins , cephalosporins , cephamycins and carbapenems . (wikidoc.org)
  • [ 47 , 48 ] Alteration of the expression of CarO in the outer membrane reduces the penetration of imipenem into the cell, therefore contributing to drug resistance. (medscape.com)
  • Overexpression of this pump, tightly regulated by adeRS genes encoding a two-component regulatory system, [ 36 ] confers resistance to aminoglycosides and decreased susceptibility to fluoroquinolones, tetracycline, chloramphenicol, erythromycin, trimethoprim and ethidium bromide, as well as to netilmicin and meropenem.

  • Variations in their structure or regulation of porin expression can provide a mechanism to escape from antibacterial pressure. (medscape.com)
