count, usually 50-100 x109/L with a left shift is a common finding in

Which of the following combinations is useful for confirming the presence
of extended spectrum beta-lactamases in E coli? - correct answer -Extended
spectrum beta lactamases (ESBL) are inhibited by clavulanic acid.
Confirmatory tests of the presence of ESBL are based on the enhanced
activity of a beta-lactam antibiotic, usually cefotaxime or ceftazidime, when
it is tested with clavulanic acid compared to the activity of the betalactam
tested alone.
