β-Lactam (beta-lactam): An amide contained within a four-membered ring, or a molecule which contains this moiety. The antibiotic activity of penicillins and
Beta-lactam antibiotics are those that contain 4-member, nitrogen-containing, beta-lactam ring at the core of their structure. This ring mimics the shape of the terminal D-Ala-D-Ala peptide sequence that serves as the substrate for cell wall transpeptidases. At present, there are four major beta-lactam subgroups.
2,3,4 Recently, cefepime has been most common beta-lactam reported to cause neurotoxicity, but other beta-lactams have been implicated. 5,6 Several studies have attempted to define neurotoxicity thresholds via Thermo Scientific Remel Beta Lactam Reagent Disc uses an acidometric method to detect beta-lactamase production in Haemophilus spp., N. gonorrhoeae and staphylococci. 2020-8-11 · A beta-lactam allergy guideline with recommendations for which antibiotics are safe to prescribe in patients with beta-lactam allergy can improve patient care by allowing these patients to receive more effective, less toxic, and/or less costly antibiotics … 2019-7-1 · Beta-lactam antibiotics are among the most commonly prescribed drugs, grouped together based upon a shared structural feature, the beta-lactam ring.

Penicillins, monobactams, carbapenems, imipenems, and cephalosporins are known chemically as beta-lactam antibiotics because as part of their chemical
Most β-lactam antibiotics work by inhibiting cell wall biosynthesis in the bacterial organism and are the most widely used group of antibiotics. Until 2003, when measured by sales, more than half of all commercially available antibiotics in use were β-lactam compounds. The first β En beta-laktam (β-laktam) är en cyklisk amid med tre kolatomer och en kväveatom i ringstrukturen. Beta-laktamerna är mest kända för att de utgör den reaktiva delen av beta-laktamantibiotika som penicillin, monobaktam, cefalosporin och karbapenem.
Beta-lactamase enzymes are produced either constitutively or on exposure to antimicrobials. These enzymes break the beta-lactam ring of vulnerable penicillin &
Bètalactamantibiotica behoren tot een groep antimicrobiële middelen die bacteriën doden door de productie van celwandcomponenten te remmen/stoppen. Deze antimicrobiële middelen danken hun naam aan de chemische structuur bètalactam. Emerging evidence shows that there is no such thing as a "penicillin allergy" or "cephalosporin allergy." Instead, cross-allergic reactions are restricted to much smaller groups of antibiotics that share greater structural similarity. This opens the door to using beta-lactam antibiotics safely in patients who have had an allergic reaction to one or more of these drugs.

β-lactam antibiotics are bactericidal, and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls. The peptidoglycan layer is important for
2020 — Metallo-beta-lactamases (MBLs) are enzymes that confer resistance to almost all available beta-lactam antibiotics, including carbapenems – a Extended Spectrum Beta-Lactamase (ESBL).

The side chains, mainly the R1 side chain, also play a role in inducing ADR-associated with beta-lactams and account for some difference between beta-lactam classes. Although allergy studies show all four types of hypersensitivity reaction are associated with beta-lactam allergy, the specific mechanism mediating beta-lactam induced fever has not yet been clearly identified. Beta-lactam antibiotic + beta-lactamase inhibitor (clavulanate potassium). Amoxicillin activity and spectrum are as described earlier. Clavulanate has no antibacterial effects alone, but it is a strong inhibitor of the beta-lactamase enzyme that causes resistance among gram-positive and gram-negative bacteria. Beta-lactam antibiotics, which are named for the beta-lactam ring in their chemical structure,1 include the penicillins, cephalosporins and related compounds. These agents are active against many Monobactamer.
