Web13 apr. 2024 · Le penicilline in associazione agli inibitori delle beta-lattamasi si confermano la classe a maggior consumo (36% dei consumi totali), seguita dai macrolidi e dai fluorochinoloni. Permane un’ ampia variabilità regionale nei consumi a carico del SSN, che sono maggiori al Sud rispetto al Nord e al Centro. Beta-lactamases, (β-lactamases) are enzymes (EC 3.5.2.6) produced by bacteria that provide multi-resistance to beta-lactam antibiotics such as penicillins, cephalosporins, cephamycins, monobactams and carbapenems (ertapenem), although carbapenems are relatively resistant to beta … Meer weergeven The structure of a Streptomyces serine β-lactamase (SBLs) is given by 1BSG.

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.
