  • Oxacillin (or cefoxitin) represents all other ß-lactams (and cephamycins) and resistance to either of these predicts non-susceptibility to all categories of ß-lactam antimicrobials i.e. all categories of penicillins, cephalosporins, ß-lactamase inhibitors and carbapenems. (cdc.gov)
  • ESBLs are beta-lactamases capable of conferring bacterial resistance to the penicillins, first-, second-, and third-generation cephalosporins, and aztreonam except the cephamycins or carbapenems with various genotypes such as CTX-M, TEM, SHV, OXA [ 16 ]. (biomedcentral.com)

  • Now, two new kits from Streck, available in the UK from Alpha Laboratories, provide a comprehensive, cost-effective molecular method to detect the most clinically important β-lactamases that confer resistance to penicillins, cephamycins and, in some cases, carbapenems. (pathologyinpractice.com)
  • Among plasmid-mediated β-lactamases, extended-spectrum β-lactamases (ESBLs) are generally known to hydrolyze cephamycins and metallo-β-lactamases (MBLs) can hydrolyze carbapenems, which cannot be easily hydrolyzed by traditional β-lactamases. (advbiores.net)
  • Resistance to cephamycins is commonly due to cells containing plasmid encoded β-lactamases. (toku-e.com)
  • Like β-lactams, cephamycins interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. (toku-e.com)
