Extended - spectrum Beta - lactamases
Beta-lactamase enzymes (BLs) have become the most worrisome mediators of antimicrobial resistance expressed by gram-negative bacteria (GNB). The multiple families of BLs have in common the ability to hydrolyze the -lactam rings of one or more members of the penicillins, cephalosporins, cephamycins, carbapenems, and monobactams. Extended-spectrum -lactamases (ESBLs) are a subset of BLs that conf...
متن کاملExtended-spectrum beta-lactamases.
At least 30 extended-spectrum beta-lactamases (ESB) have emerged responsible for resistance to indigestible beta-lactams (C3G) since their discovery in West Germany in 1983. Most of them are produced by enterobacteria and essentially K. pneumoniae which appeared susceptible to oxyimino-beta-lactams. A double-disk test was useful to detect such nosocomial isolates of enterobacteria (urines, bloo...
متن کاملCo Existence of Ampc and Extended Spectrum Beta Lactamases Resistance in Metallo Beta Lactamases Producing Strains of Pseudomonas Aeruginosa
Pseudomonas aeruginosa is one of the commonest multi drug resistant bacteria causing nosocomial infection and Metallo-Beta-Lactamase production is one of the important reasons. The following study was conducted to determine incidence of MBL producing P.aeruginosa. and co existence of AmpC and ESBL production. Screening for MBL was done using imipenem disk and all the isolates found resistant we...
متن کاملFrequency of E. coli clinical isolates producing blaSHV and blaTEM extended-spectrum beta-lactamases
Introduction: Production of extended-spectrum beta-lactamase enzymes (ESBLs) in E. coli creates many problems for patients. These enzymes are located on transferable elements and can hydrolyze penicillins, broad-spectrum cephalosporins, and aztreonam. This study aimed to determine the clinical isolates of E. coli producing ESBLs of blaSHV and blaTEM in the city of Zanjan. Methods: This cross...
متن کاملAntibiotic Resistance Pattern and the Prevalence of Extended Spectrum Beta-Lactamases (ESBLs) in Urinary Isolates of Klebsiella Pneumoniae
Abstract Background and Objective: Klebsiella pneumoniae is an opportunistic nosocomial pathogen causing a variety of infections including urinary tract infections, pneumonia, septicemia, wound infections and infections in the intensive care units. Since the ESBL producing Klebsiella pneumoniae strains are increasingly causing urinary tract infections, we aim to assess antibiotic resistance pat...
