ai: The result of phenotypic detection of ESBL-producing Pseudomonas aeruginosa by Double-Disk Confirmatory Test (DDCT) in Pseudomonas aeruginosa. A: Ceftazidime (30 µg); B: ceftazidime + clavulanate (30/10µg); C: cefotaxime + clavulanate (30/10µg); D: cefotaxime (30 µg). Top: ESBL negative strain; Bottom: ESBL positive strain; ESBL positive isolates show an increase of 5 mm zone of inhibition with clavulanic acid as compared to the zone size for CTX and CZD alone. aii: The result of phenotypic detection of MBL-producing Pseudomonas aeruginosa by EDTA-imipenem microbiological (EIM) test in Pseudomonas aeruginosa. A: EDTA + imipenem; B: imipenem. Top: MBL positive strain; Bottom: MBL negative strain; MBL considered positive when zone diameter difference between imipenem + EDTA and imipenem discs was larger than 7 mm.
