ß-Lactams: Mechanisms of Action and Resistance - YouTube
Since allergic responses to penicillins & other beta-lactams are known to occur, a common clinical question is “can an individual with a “bonafied” Ig-E mediated beta-lactam (e.g. penicillin ) allergy, that potentially could produce an anphylactoid reaction, safely take a structurally-related antibiotic, such as a cephalosporin, carbapenem, or monobactam. The answer is …
Beta Lactam Mechanism of Action - YouTube
Although almost all isolates of K. pneumoniae were initially considered to be susceptible to cephalosporins, studies over the last two decades have shown variable susceptibility to this antibiotic class. This reduced susceptibility has been predominantly mediated by plasmid-mediated extended-spectrum beta-lactamases (ESBLs) and to a lesser extent, plasmid-mediated AmpC type beta-lactamases.
The penicillin antibiotics consist of a and a variety of side chains. The beta-lactam ring or the side chains may participate in hypersensitivity reactions (, ). The specific haptens have not been identified ().
