Simple assay of beta-lactamase with agar medium containing a chromogenic cephalosporin, pyridinium-2-azo-p-dimethylaniline chromophore (PADAC).
A new beta-lactamase assay method with agar plates containing pyridinium-2-azo-p-dimethylaniline chromophore (PADAC) (50 microM), a beta-lactamase-labile, chromogenic cephalosporin, was examined. On the PADAC plates inoculated with beta-lactamase-producing gram-negative bacteria (10(4) CFU per spot) and incubated at 37 degrees C, a yellow zone showing hydrolysis of PADAC by beta-lactamase was f...
متن کاملFrequency of extended spectrum beta lactamase producer P. aeruginosa strains isolated from burned patients of Motahari hospital, Teharan, Iran
Pseudomonas aeruginosa is an opportunistic pathogen which is naturally resistant to a large range of antibiotics like lots of Beta–Lactams (penicillins, cephalosporins and carbapenems) and may cause additional resistance after unsuccessful treatment. The understanding of beta-lactamase identification and detection in these bacteria is very valuable. In recent years a number of variety of new be...

Introduction: Carbapenems are one of the latest drugs for treatment of threatening infections of Pseudomonas aeruginosa. Resistance to these antibiotics is sometimes caused by carbapnmase class B, such as VIM metallo-beta-lactamase (MBL) that is growing in the communities. The aim of this study was to detect the of metallo-beta-lactamase blaVIM-1 gene among clinical isolates of Pseudomonas aeru...
متن کاملRapid penicillinase paper strip test for detection of beta-lactamase-producing Haemophilus influenzae and Neisseria gonorrhoeae.
A modified 1-min iodometric paper strip test for penicillinase activity was developed for detection of beta-lactamase-producing isolates of Haemophilus influenzae and Neisseria gonorrhoeae. The test is simple to perform and uses reagent-impregnated strips that may be stored for 1 year or more prior to use.

Background & objective: Beta-lactam antibiotics resistance specifically Imipenem and Meropenem, the last choices of treatment, causes fatal events in patients with P.aeruginosa infection. The aim of this study was to detect the VIM and IMP of metallo-beta-lactamase genes in 103 isolates of P. aeruginosa in two Iranian hospitals. <strong...
