Antibiotic impregnated tablets for screening ESBL and AmpC beta lactamases
Antibiotic resistance is a growing threat. Fifty non repetitive multi drug resistant gram negative bacterial isolates were screened for ESBL, AmpC, ESBL-AmpC co-production using antibiotic tablets. Of these 56% were Escherichia coli, 16% were Klebsiella spp., 39.6% produced ESBLs, 17.2% AmpC and 13.8% showed co-production. Antibiotic tablets sensitivity for ESBL detection was 93.9% compared to ...
متن کاملOccurrence of ESBL & Amp-C beta-lactamases & susceptibility to newer antimicrobial agents in complicated UTI.
BACKGROUND & OBJECTIVE Production of extended spectrum beta-lactamases (ESBLs) and AmpC beta-lactamases are the most common mechanisms of antimicrobial resistance in Gram negative bacilli. A prospective study was undertaken to know the occurrence of ESBL and AmpC producing strains and their antibiotic susceptibilities to newer agents to guide empirical therapy for complicated urinary tract infe...
متن کاملExtended - 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 کاملNew diagnostic microarray (Check-KPC ESBL) for detection and identification of extended-spectrum beta-lactamases in highly resistant Enterobacteriaceae.
The performance of a microarray for the detection of extended-spectrum beta-lactamases was determined on a collection of 638 highly resistant members of the family Enterobacteriaceae collected from patients in 18 hospitals in The Netherlands. The microarray had a significantly higher specificity than the phenotypic assays. It also detects carbapenemases and characterizes the resistance genes, p...
