Resistance of Pseudomonas aeruginosa to multiple β-lactam antibiotics

Abstract

A total of 90 Pseudomonas aeruginosa (P.aeruginosa) strains clinical samples were  collected from burn, ear, and foot diabetic samples in Al-Hilla, and Marjan teaching hospitals were identified to species level with a VITEK-2 system. The susceptibility to 11 antibiotics were tested using disc diffusion test resulting in 55.4% of 90 P.aeruginosa isolates were resistant to 11 antibiotics. Cefinase discs impregnated with nitrocefin method was used for the detection of β-lactamase production in antibiotics resistant 90 P.aeruginosa isolates. Results showed that 56% isolates were able to produce β-lactamase.
