UMADEVI, Sivaraman et al. Detection of extended spectrum beta lactamases, ampc beta lactamases and metallobetalactamases in clinical isolates of ceftazidime resistant Pseudomonas Aeruginosa. Braz. J. Microbiol. [online]. 2011, vol.42, n.4, pp.1284-1288. ISSN 1517-8382.

We studied the prevalence of ceftazidime resistance in Pseudomonas aeruginosa and the rates of extended-spectrum β-lactamase (ESBL), AmpC β-lactamase (AmpC) and metallo-β-lactamase (MBL) production among the ceftazidime resistant Pseudomonas aeruginosa. A very high rate of MBL production was observed, which suggested it to be an important contributing factor for ceftazidime resistance among Pseudomonas aeruginosa.

Keywords : Extended-spectrum β-lactamases; AmpC; metallo-β-lactamases; ceftazidime resistance; Pseudomonas aeruginosa.
