Extended-spectrum β-lactamase (ESBL)-producing Enterobacteracterales such as E. coli, Klebsiella spp. and Proteus spp. are called ESBL producers. Due to the specific ß-lactamase with extended spectrum of activity, the bacteria are resistant to β-lactam antibiotics including penicillin and cephalosporin antibiotics (also to 3rd and 4th generation cephalosporins). The property of ESBL formation is encoded on easily transferable genetic segments and can be transferred from one bacterial generation to the next during reproduction (vertical transfer) or exchanged between bacteria (horizontal transfer).
Testing for ESBL is also part of the service Analysis of Multidrugresistant Bacteria.
