METHOD FOR DISCRIMINATING BACTERIUM FOR PRODUCING EXPANDED SUBSTRATE TYPE BETA-LACTAMASE(ESBL)

摘要

PROBLEM TO BE SOLVED: To provide a discrimination method for easily confirming an ESBL- producing bacterium which is considered as a bacterium causing hospital infection. SOLUTION: The subject of the invention is achieved by an ESBL-producing bacterium discrimination method which comprises a disk diffusion method using a combination of a cefpodoxime-containing disk with a cefpodoxime/β-lactamase inhibitor-containing disk, or an ESBL-producing bacterium discrimination method which comprises a microliquid dilution method (MIC measurement) using a combination of a cefpodoxime-containing liquid culture medium with a cefpodoxime/β-lactamase inhibitor-containing liquid culture medium.
