conclusions the high prevalence of quinolone resistance genes, which indicates antibiotic resistance, in the imam reza hospital of mashhad is a major concern. hence, the antibiotics prescription policy should be revised, and infection control measures should be improved. results eighty-six (43%) isolates were ciprofloxacin-resistant. the pct identified 85 (42.5%) of 200 e. coli isolates as esbl...
conclusions the levels of resistance to ceftazidime were remarkably variable among ctx-mproducers. this study provides further evidences of the global dissemination of ctx-m type esbls and emphasized on the need for their epidemiological monitoring. results in phenotypic confirmatory test, 154 (44%) out of 350 clinical isolates were esbl positive. using molecular assay, 154 strains potentially ...
objective(s) resistance to the new generation of cephalosporins which is mediated by extended-spectrum beta-lactamases (esbls) has been found among escherichia coli isolates throughout the world. these resistance genes and their producers, the micro-organisms carrying beta-lactamases, are responsible for serious clinical and therapeutic problems among inpatients and it is necessary to pay more ...
abstract background: pseudomonas aeruginosa is one of the most common gram negative bacteria involved in nosocomial infections. presence of extended-spectrum beta-lactamases (esbls) genes, play an important role in induction of resistance in beta-lactamase producing species to beta lactam antibiotics. frequency of resistance to these antibiotics is increasing. in this study, antibiotic sensitiv...
Background & Aim: clinical cases especially from hospitalized patients. Recently multiple drug resistant isolated from clinical cases. Resistances were seen against drugs belonging to different antibiotic families. In thissurvey, drug resistance in clinical isolates was studied with special reference to extended spectrum betalactamases.Escherichia coli is one of the most important and prevalent...
The study emphasizes the reasons use of beta-lactamase inhibitors in combination with beta-lactam antibiotics. ß-lactam-ß-lactamase inhibitors are currently the most successful strategy for infections caused by extended-spectrum β-lactamase and carbapenemases bacteria.
Lytic Activity of Isolated Phage from Milk Against Extended-Spectrum Beta-Lactamase Escherichia coli
Background and purpose: Escherichia coli (E.coli) is the most common cause of urinary tract infection. The treatment strategy has been hampered by the emergence of broad-spectrum beta-lactamase-producing E.coli and its resistance to most antibiotics. Bacteriophages are suggested as an alternative treatment option. This study aimed at evaluating the lytic activity of isolated phage from unpaste...
begin{abstract} the relations between the spectrum of the matrix $q+r$ and the spectra of the matrices $(gamma + delta)q+(alpha + beta)r-qr-rq$, $qr-rq$, $alpha beta r-qrq$, $alpha rqr-(qr)^{2}$, and $beta r-qr$ have been given on condition that the matrix $q+r$ is diagonalizable, where $q$, $r$ are ${alpha, beta}$-quadratic matrix and ${gamma, delta}$-quadratic matrix, respectively, of order $...
begin{abstract} The relations between the spectrum of the matrix $Q+R$ and the spectra of the matrices $(gamma + delta)Q+(alpha + beta)R-QR-RQ$, $QR-RQ$, $alpha beta R-QRQ$, $alpha RQR-(QR)^{2}$, and $beta R-QR$ have been given on condition that the matrix $Q+R$ is diagonalizable, where $Q$, $R$ are ${alpha, beta}$-quadratic matrix and ${gamma, delta}$-quadratic matrix, respectively, of ord...
