Prevalence of Plasmid-Mediated Quinolones Resistance among Klebsiella pneumoniae Strains Isolated from Hospitals in Borujerd, Iran
ABSTRACT Background and Objective: Klebsiella pneumoniae is one of the most common causes of bacterial infections. Presence of plasmid-mediated quinolone resistance genes causes low level of resistance in K. pneumoniae. This study investigated the prevalence of resistance to quinolones and fluoroquinolones, and the frequency of qnrA, qnrB and qnrS genes amo...
متن کاملPlasmid- mediated cefotaxime and ceftizoximd resistance in Ten strains of klebsiella pneumoniae isolated from hospitals in Kerman,Iran
Klebsiella pneumonia is a gram negative bacillus of which it's resistant strains are a common source of nosocomial infections . The goal of this study is determination of drug sensitivity of these resistant strains, and study of causes involved in the resistant especially the presence of plasmid. Ten different strains of klebsiella pneumoniae were isolated from clinical specimens collected from...
متن کاملPlasmid Curing Activity of Five Plant Extracts on Multiple Resistant Plasmid Bearing Klebsiella Pnumoniae Strains
ABSTRACT The curing of five medicinal plant extracts (Satureia hortensis, Glycyrrhiza glabra, Teucrium Pollium, Myrtus Communis, Eukalypetus globolus) on plasmid bearing strains of klebsilla pnenmoniae resistance to multiple antibiotics were investigated. Alcoholic and maceration extraction were carried out from leaves, fruits or roots of the above plants. Mimimum inhibitory concentrations (MI...
متن کاملPlasmid-to-plasmid recombination in Haemophilus influenzae.
No recombination between plasmids was observed after conjugal transfer of a plasmid into a cell carrying another plasmid. Two types of such recombination took place after transformation, one type being Rec+ dependent and suggesting a preferred site of recombination. The other much rarer type was at least partially Rec+ independent.
متن کاملMucoid phenotype of Klebsiella pneumoniae is a plasmid-encoded virulence factor.
We have previously reported that the presence of a 180-kilobase plasmid encoding production of aerobactin was correlated with the virulence of Klebsiella pneumoniae K1 and K2 isolates. This work demonstrates that a variant of a K2 strain which has lost this plasmid, pKP100, becomes avirulent. Labeling of this plasmid with the mobilizable, replication-defective element pME28, used here as a mobi...
