BETA-LACTAMASE PRODUCTION

The production of beta-lactamase enzymes by Gram negative bacteria including E. coli, P. aeruginosa and Klebsiella species is an important mechanism by which the organisms evade both in vivo and in vitro antimicrobial onslaught. Beta-lactamase production by resistant test isolates can be evaluated for beta-lactamase production using the Nitrocefin test sticks (Oxoid, UK). The nitrocefin […]
