detection of extended-spectrum β-lactamases (esbls) in escherichia coli

background escherichia coli (e. coli) species are able to produce extended-spectrum β-lactamases (esbls) that cause high resistance to the beta-lactam antibiotics. therefore, determining the antibiotic susceptibility patterns in resistant organisms is necessary for suitable therapeutic approaches. patients and methods totally, 260 clinical isolates of e. coli were collected from hospitals in te...

[The widening challenge of extended spectrum β-lactamases].

Since 1980, the prescription of new semi-synthetic molecules of third generation cephalosporins changed the course of modern medicine. However, the acquired resistance against these antibiotics was rapidly developed with the production of extended spectrum β-lactamases (ESBL) (TEM and SHV types) disseminated mainly by nosocomial Klebsiella pneumoniae clones. Since around 2000, we are facing a w...
