Extended-Spectrum -Lactamases: a Clinical Update
s of the International Congress of Chemotherapy, Birmingham, England, 1999). In 1989 an outbreak of multiresistant Salmonella enterica serovar Typhimurium infections occurred in 12 of 14 Argentinian provinces. From these isolates a new non-SHV, non-TEM ESBL named CTX-M-2 was identified (26, 28, 29, 333). Organisms with CTX-M-2 have spread throughout many parts of South America (333). Other CTX-...

Recently, tigecycline has been added ...
متن کاملExtended-spectrum beta-lactamases: a brief clinical update.
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...

ABSTRACT Background and Objectives: Pseudomonas aeruginosa is an opportunistic pathogen resistant to various antibiotics. The aim of the present study was to study resistant patterns in clinical isolates of P. aeruginosa, classify them into pandrug resistance (PDR), extensive drug resistance (XDR) and multidrug resistance (MDR)...
متن کاملPrevalence of blaCTX-M Gene among Extended- Spectrum β-Lactamases Producing Klebsiella pneumoniae Clinical Isolates in Iran: A Meta-Analysis
Background: CTX-M-type extended-spectrum β-lactamases (ESBLs) are the most prevalent ESBLs in bacterial members of Enterobacteriaceae family including Klebsiella pneumoniae. The global spread of CTX-M-producing K. pneumoniae is a major concern in most countries including Iran. The aim of this meta-analysis was to determine the relative frequency (RF) of blaCTX-M gene among ESBLs-producing K. pn...
