Transformation and transfection of Pseudomonas aeruginosa: effects of metal ions.

PLASMID MEDIATED METAL AND ANTIBIOTIC RESISTANCE IN PSEUDOMONAS AERUGINOSA STRAINS ISOLATED FROM BURN PATIENTS

Pseudomonas aeruginosa is a leading cause of bum infections, and antibiotic- resistant strains of this bacterium are emerging due to extensive application of antibiotics in the bum unit of hospitals. In this study 50 strains of P. aeruginosa were isolated from bum patients infected with this micro-organism in the bum unit of a general hospital in Kerman, Iran over one year [May 1999-ApriI20...

Detection of Heavy Metals Resistance Genes and Effects of Iron Nanoparticles on the Gene Expression in Pseudomonas Aeruginosa Using Real-Time PCR

Background: Heavy metals enter the environment through industrial activities and contaminate natural ecosystems. Identification of heavy metal-resistant bacteria plays an important role in environmental pollution and ultimately cleansing it. Therefore, the aim of the present study was to isolate the resistant genes of Pseudomonas aeruginosa and the effects of nanoparticles on gene expression u...

Synthesis, Characterization, Electrochemical and Antimicrobial Studies of N4-Macrocycles of Cobalt(II) and Nickel(II) Metal Ions

The precise analysis of redox chemistry of MN4-based macrocyclic complexes is of great importance because of stabilization of unusual oxidation states of metal ions by macrocyclic ligand and thus have various applications in biochemistry, electrochemistry, electrocatalysis, pharmaceuticals etc. In this work, MN4-macrocyclic complexes of Co (II) and Ni(II) transition metal ...

Metal Accumulation in Pseudomonas aeruginosa Occur in the Form of Nanoparticles on the Cell Surface

Characterization and Assessment of Antimicrobial Activity and Potential of Heavy Metal ion Detection of Silver Nanoparticles synthesized from Actinidia deliciosa paste using double distilled water and 70% ethanol as solvent

Green synthesis of nanoparticles using plants as sources exhibiting superiority over the physical and chemical methods that are expensive and can involve the use of toxic, hazardous chemicals, which may pose biological and environmental risks. In present study silver nanoparticles were synthesized in single step by biological method using extracts of Actinidia deliciosa paste as reducing and st...
