WebTEM-type are the most prevalent beta-lactamases in enterobacteria; they hydrolyze the beta-lactam bond in susceptible beta-lactam antibiotics, thus conferring resistance to penicillins and cephalosporins. TEM-3 and TEM-4 are capable of hydrolyzing cefotaxime and ceftazidime. TEM-5 is capable of hydrolyzing ceftazidime. WebJul 17, 2014 · Extended-spectrum beta-lactamases (ESBLs) have the ability to hydrolyze various types of the newer beta-lactam antibiotics, including extended-spectrum cephalosporins of the 3 rd and 4 th generation (e.g. cefotaxime, ceftriaxone, ceftazidime) and monobactams (e.g. aztreonam), which were assessed as “critically important …
WebNovel plasmid-mediated beta-lactamase in clinical isolates of Klebsiella pneumoniae more resistant to ceftazidime than to other broad-spectrum cephalosporins. Antimicrob Agents Chemother. 1988 May;32(5):626–630. [ PMC free article] [ PubMed] [ Google Scholar] WebESBLs belong to the TEM, SHV, and CTX-M classes [11]. TEM BLs have amino acid substitutions around the active site of the enzyme that change the configuration to allow hydrolysis of oxymino-beta-lactam substrates [11]. Based on the type of change, hundreds of TEM-type enzymes have been described to date [12]. SHV-type ESBLs also
WebMar 26, 2024 · TEM, CTX and SHV genes were detected in strains known as EPE phenotypically. The results showed that the detection rate of EPE strains in enteric birds is higher than apparently healthy birds (25.6 vs. 16.2%). The CTX gene was the highest ESBL gene. The SHV gene was not detected in any of E. coli strains.
