Detection of blaOXA-145, blaOXA-224, blaOXA-539, and blaOXA-675 Genes and Carbapenem-Hydrolyzing Class D β-Lactamases (CHDLs) in Clinical Isolates of Pseudomonas aeruginosa Collected from West of Iran, Hamadan

The result of phenotypic detection of MBL-producing Pseudomonas aeruginosa by the 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 the zone diameter difference between imipenem + EDTA and imipenem discs was larger than 7 mm (right).
