Abstract
Pseudomonas aeruginosa is the most common pathogen causing nosocomial infections. Extended spectrum β-lactamases (ESBLs) producing gram negative bacteria are an increasing problem worldwide. A total of 48 pseudomonas aeruginosa strains were isolated and identified by API 20NE system. ESBL producing strains were detected phenotypically and genotypically. ESBL producers were 79.2% (38 out of 48 strains). PCR assay considered a gold standard method as it was detected all ESBL producers. However the phenotypic tests showed lower sensitivity in the detection. 77.1% of isolates were sensitive to Imipenem, 75% were sensitive to Aztronam, 68.8% were sensitive to Ciprofloxacin and 66.7% were sensitive to Gentamicin. Carpabenem remain the antibiotic of choice for managing of this infection.
