- They are highly susceptible in vitro to β-lactamase inhibitors such as clavulanic acid, but not cephamycins or carbapenems [2]. (who.int)
- 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)
- Extended-spectrum β-lactamases (ESBLs) create significant therapeutic problems by inactivating almost all β-lactams except cephamycins and carbapenems. (biomedcentral.com)
- Beta-lactamases are enzymes produced by some bacteria that provide resistance to beta-lactam antibiotics like penicillins, cephamycins, and carbapenems(ertapenem), although carbapenems are relatively resistant to beta-lactamase. (ucsf.edu)
- Ampicillin and amoxicillin, first- and second-generation cephalosporins, and cephamycins are strong AmpC beta-lactamase inducers. (medscape.com)
- They also are usually resistant to cephamycins such as cefoxitin. (medscape.com)
- CMY-11 β-lactamase genes from nine clinical isolates that were responsible for resistance to cephamycins (cefoxitin and cefotetan), amoxicillin, cephalothin and amoxicillin-clavulanic acid, were cloned and characterised. (elsevierpure.com)
- This new class of beta-lactam antibiotics, the cephamycins, are characterized by a 7-alphamethoxy-beta-lactam. (cathaydrug.com)
- Extended broad spectrum β-lactamase in Klebsiella pneumoniae including resistance to cephamycins. (geneticsmr.com)
- The results from ERIC-PCR revealed that dissemination of CMY-11 was due to outbreaks of resistant species and to the intra-species spread of resistance to cephamycins in Korea. (elsevierpure.com)
- reported that 0.16% of E. coli were resistant to cephamycins ( 3 ). (cdc.gov)
- Among the 51 clinical isolates collected from a university hospital in Korea, nine isolates were resistant to cephamycins. (elsevierpure.com)
