Extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae with Cefotaximase-München (CTX-M) enzymes are rapidly increasing worldwide and pose a threat to health care. ESBLs with CTX-M enzymes have been isolated from animals and different food products, but it is unknown if food imported from the Mediterranean area may be a possible reservoir of these bacteria. During 2007-2008, swab sam...
Background and objective: Extended Spectrum Beta lactamases (ESBL) such as TEM (Temoneria) is one of the bases of antibiotic resistance in Escherichia coli isolates. The aim of this study was evaluation of TEM Extended Spectrum Beta lactamase producing E. coli, in clinical samples isolated from Zanjan hospitals, by phenotypic and PCR methods. Materials and Methods: In this cross-sectional study...
Background and Aim: The emergence of nonfermenter bacteria that are resistant to multidrug resistant ESBL are nowadays a principal problem for hospitalized patients. The present study aimed at surveying the emergence of nonfermenter bacteria resistant to multi-drug ESBL producing isolated from patients blood samples using BACTEC 9240 automatic system in Shiraz. Materials and Methods: In ...
Prevalence of extended spectrum beta-lactamase producing anaerobic bacteria in chronic periodontitis
Background and Objective: Extended spectrum beta-lactamases (ESBLs) are defined as enzymes capable of hydrolyzing oxyimino-cephalosporins. Selective pressure of overuse of new antibiotics may be associated with emergence of new types of beta-lactamases. The aim of this study was to identify urinary isolates of CTX-M ESBL-producing Klebsiella pneumoniae and to detect their pattern of antibiotic ...
conclusions the results of this study phenotypically and genotypically confirmed the high frequency of esbl-producing strains, such as the ctx-m and ctx-m-1 genes, among enterobacteriaceae isolates in our region. therefore, use of antibiotic susceptibility testing for the detection of esbl isolates prior to the prescription of beta-lactam antibiotics is recommended. this could help prevent the ...
We evaluated the use of a trypticase soy broth (TSB) for improving detection of extended-spectrum-beta-lactamase-producing (ESBL(+)) bacteria. Preenrichment of throat and rectal swabs in TSB prior to inoculation on solid medium doubled the number of ESBL(+) bacteria detected in samples obtained from patients in our intensive care unit.
