BACKGROUND & AIM The aim of this study was the detection of OqxAB efflux pumps, OmpK35 and OmpK36 porins among extended-spectrum-β-lactamase-producing Klebsiella pneumoniae isolates from Iran. MATERIALS AND METHODS This study was conducted with 83 K. pneumoniae isolates from two hospitals in Tehran, Iran. Antibiotic susceptibility tests were performed by(More)
Carbapenem resistance due to acquired metallo-beta-lactamases (MBLs) is considered to be more serious than other resistance mechanisms. The aim of this study was to evaluate the antibacterial activity of Zataria multiflora Boiss and Carum copticum plants on IMP-producing P.aeruginosa strains. This experimental study was carried out on hospitalized burn(More)
OBJECTIVE There are few therapeutic options for treatment of multidrug resistant Klebsiella pneumoniae isolates as a hospital infectious agent (nosocomial infection). The aim of this study was to evaluate the antibacterial activity of Zataria multiflora Boiss extracts against ESBL-producing Klebsiella pneumoniae strains. MATERIALS AND METHODS This study(More)
Pseudomonas aeruginosa is one of the major bacteria causing acute infections. β-Lactamase production is the principal defense mechanism in gram-negative bacteria. The aim of our study was to evaluate the antibacterial activity of Methanolic Extracts of Green and Black Teas on P. aeruginosa Extended Spectrum-β-Lactamases (ESBLs) production. This research was(More)
BACKGROUND The purpose of the present study was the distribution of blaOXA-1, blaPER-1 and blaVEB genes and the genotyping of these genes in extended-spectrum β-lactamases (ESBL) producing uropathogenic and diarrheagenic Escherichia coli isolates. METHODS Of 432 isolates, 58 uropathogenic E. coli (UPEC) and 56 diarrheagenic E. coli (DEC) isolates were(More)
Background: Listeria monocytogenes, as one of the foodborne pathogens, is a causative agent of listeriosis. The transfer of L. monocytogenes bacteremia in pregnant women occurs as self-limited flu-like symptoms, but it may result in abortion, stillbirth or premature birth of the infected baby. One of the best methods for detection of this bacterium is(More)
The bladder wall is coated with various mannosylated proteins which interfere with the binding of bacteria to the uroepithelium. As binding is an important factor in establishing pathogenicity for these organisms, its disruption results in reduced capacity for invasion of the tissues.[1a,b] Moreover, the unbound bacteria are more easily removed when(More)
