Pseudomonas aeruginosa is a gram-negative, obligate aerobic bacil which is widespread in world and causes burned hospital infections in humans. Multidrug resistant strains of Pseudomonas aeuginosa (MDR) have been emerged as alarming nosocomial pathogens among burned patients in Tehran (Iran). Integrons play important role in drug resistant in bacteria. Aminoglycosides are common antibiotics whi...

PURPOSE Antimicrobial resistance monitoring could be a useful source of information for treating and controlling nosocomial infections. We analyzed antimicrobial resistance data generated by Korean Hospitals and by a commercial laboratory in 2005 and 2007. MATERIALS AND METHODS Susceptibility data for 2005 and 2007 were collected from 37 and 41 hospitals, respectively, and from one commercial...

Pseudomonas aeruginosa is extremely resistant to triclosan. Previous studies have shown that P. aeruginosa encodes a triclosan-resistant enoyl-acyl-carrier protein reductase (ENR), FabV, and that deletion of fabV causes P. aeruginosa to be extremely sensitive to triclosan. In this report, we complemented a P. aeruginosa fabV deletion strain with several triclosan-resistant ENR encoding genes, i...

metallo-β-lactamase (mbl) producing pseudomonas aeruginosa has been reported to be an important nosocomial infection. its intrinsic and acquired resistance to various antimicrobial agents and its ability to develop multidrug resistance imposes a serious therapeutic problem. different clinical samples were collected from public and private hospitals in baghdad city, iraq. bacterial identificatio...

Broad-host-range plasmids coding for beta-lactamase were successfully selected after transformation of Pseudomonas strains. Transformants of both Pseudomonas aeruginosa and Pseudomonas putida containing plasmid pRO1614 were isolated in media containing low concentrations of piperacillin. These strains were also susceptible to other ureidopenicillins. Similar selections of transformants with car...

Objective(s): Resistance to carbapenems is the principal reason for the continuing utilization of colistin as a last resort choice for treating the infections resulted from multidrug carbapenem-resistant Pseudomonas aeruginosa (CRPA) isolates. The assessment of antimicrobial resistance pattern, the prevalence of carbapenem-resistance determinants, and molecular epidemiology of colistin-resistan...

Pseudomonas Aeruginosa is one of the leading opportunistic infectious agents especially in immune-suppressed patients such like burn victims. Carbapenems like Imipenem (IMP) and Meropenem (MEM) are the choice antimicrobial drugs, which used in the treatment of Penicillin and Aminoglycoside-resistant Pseudomonas Aeruginosa isolates. Based on the importance of the detection of infectious source a...

Thirty-five patients underwent 38 treatment courses with cefotaxime. Documented infections included 11 bacteremias, 7 cases of nosocomial pneumonia, 6 surgical wound infections, 3 bone infections, 1 biliary infection, and 1 urinary tract infection. Granulocytopenic patients with fever received 15 courses of empiric cefotaxime therapy alone; in 8 courses, no definite site of infection or pathoge...

The antibacterial activity and enzymatic inactivation of lividomycin, a new aminoglycosidic antibiotic, were studied with 13 strains of Pseudomonas aeruginosa. The minimal inhibitory concentration of lividomycin was 12.5 to 25 mug/ml, and three strains were resistant to high concentrations of lividomycin (more than 200 mug/ml). It was found that P. aeruginosa TI-13 and K-11, highly lividomycin-...

Bacterial resistance is an emerging public health issue that is disseminated worldwide. Silver nanocomposite can be an alternative strategy to avoid Gram-positive and Gram-negative bacteria growth, including multidrug-resistant strains. In the present study a silver nanocomposite was synthesized, using a new green chemistry process, by the addition of silver nitrate (1.10-3 mol·L-1) into a ferm...
