Noun
ESBL (plural ESBLs)
(medicine, biochemistry, microbiology) Initialism of extended-spectrum beta-lactamase.
Amino acid substitutions in OXA enzymes can also give the ESBL phenotype. Source: Internet
Plasmids responsible for ESBL production frequently carry genes encoding resistance to other drug classes (for example, aminoglycosides). Source: Internet
The amino acid substitutions responsible for the extended-spectrum beta lactamase (ESBL) phenotype cluster around the active site of the enzyme and change its configuration, allowing access to oxyimino-beta-lactam substrates. Source: Internet
