Exempel på hur man kan använda BETA-LACTAMASE i en mening

• In addition, cephamycins have been shown to be stable against extended-spectrum beta-lactamase (ESBL) producing organisms, although their use in clinical practice is lacking for this indication.
• Cloxacillin is used against staphylococci that produce beta-lactamase, due to its large R chain, which does not allow the beta-lactamases to bind.
• The carboxypenicillins are susceptible to degradation by beta-lactamase enzymes, although they are more resistant than ampicillin to degradation.
• When used alone, piperacillin lacks strong activity against the Gram-positive pathogens such as Staphylococcus aureus, as the beta-lactam ring is hydrolyzed by the bacteria's beta-lactamase.
• Cilastatin itself does not have antibiotic activity, although it has been proved to be active against a zinc-dependent beta-lactamase that usually confers antibiotic resistance to certain bacteria, more precisely, the carbapenem family of antibiotics.
• Resistance to cephalosporins and aztreonam may arise through induction of a plasmid-based extended spectrum beta-lactamase (ESBL) or plasmid-based ampC-type enzyme.
• Ampicillin/sulbactam is a fixed-dose combination medication of the common penicillin-derived antibiotic ampicillin and sulbactam, an inhibitor of bacterial beta-lactamase.
• Usually enzymes which confer resistance to nutrient deprivation or antibiotics, such as dihydrofolate reductase or beta-lactamase respectively, or proteins that give colorimetric or fluorescent signals are used as reporters.
• Rather than having the typical four beta-strands in a sheet, beta-lactamase inhibitor protein-II only has three beta-strands per sheet while the phytase of Bacillus subtilis has five beta-strands per beta-sheet.
• Examples include chimeric and humanized minretumomab, as well as a fusion protein of a minretumomab single-chain variable fragment and the enzyme beta-lactamase.
• Currently available beta-lactamase inhibitors are effective against Ambler Class A beta-lactamases (tazobactam, clavulanate, and sulbactam) or against Ambler Class A, C and some Class D beta-lactamases (avibactam).
• Antimicrobial options include penicillinase-resistant penicillins (ex: cloxacillin, dicloxacillin) or a combination of a penicillin and a beta-lactamase inhibitor.
• While cephalosporinases (a type of beta-lactamase that inactivates cephalosporins) confers resistance to other cephalosporins, cephalosporinases have not yet been identified as a mechanism of resistance to ceftaroline.
• ESCAPPM or ESCHAAPPM is a mnemonic for the organisms with inducible beta-lactamase activity that is chromosomally mediated.
• The gene for NDM-1 is one member of a large gene family that encodes beta-lactamase enzymes called carbapenemases.
• Often multiple beta-lactamase genes are found on the same plasmid hydrolyzing a wide spectrum of beta-lactam antibiotics.
• Nitrocefin is a chromogenic cephalosporin substrate routinely used to detect the presence of beta-lactamase enzymes produced by various microbes.
• Penicilloic acid is any of several acids which are obtained from the penicillins by the hydrolytic opening of the lactam ring (as by the action of a beta-lactamase).
• Cyclized beta-lactamase, phytase, firefly luciferase, and xylanase (to name a few) have shown retained enzyme activity even after being subjected to heat at 100 °C.
• It contains sulbactam, a beta-lactam antibacterial and beta-lactamase inhibitor; and durlobactam, a beta-lactamase inhibitor.
