An intragenic probe derived from the multidrug resistance gene oprM hybridized with genomic DNA from all 20 serotypes of Pseudomonas aeruginosa and from all 34 environmental and clinical isolates tested, indicating that the MexA-MexB-OprM multidrug efflux system is highly conserved in this organism. The oprM probe also hybridized with genomic DNA from Pseudomonas aureofaciens, Pseudomonas chlor...

In cystic fibrosis (CF) patients, chronic airway infection by Pseudomonas leads to progressive lung destruction ultimately requiring lung transplantation (LT). Following LT, CF-adapted Pseudomonas strains, potentially originating from the sinuses, may seed the allograft leading to infections and reduced allograft survival. We investigated whether CF-adapted Pseudomonas populations invade the do...

The production of the soluble cytochrome oxidase/nitrite reductase in the bacterium Pseudomonas aeruginosa is favoured by anaerobic conditions and the presence of KNO3(20g/l) in the culture medium. Of three methods commonly used for the disruption of bacterial suspensions (ultrasonication, liquid-shear homogenization and glass-bead grinding), sonication proved the most efficient in releasing th...

to study the effect of chemical and biological fertilizers on growth and essential oil content of lavender (lavandula angustifolia mill.), the present work was conducted in 2012-2013 at the experimental field of alborz research station of the research institute of forests and rangelands, karaj, iran. the experiment was conducted in factorial in the form of a randomized complete block design wit...

nosocomial infection is an important prognostic factor in out comes of burned patients. in this descriptive cross. sectional study, 82 burned patients and related medical equipment were assessed in zareh hospital in 2033-2004. pseudomonas aeruginosa and staphylococcus areus were found in 69(51.4%) and 31 (23.2%) of 134 clinical specimens respectively. hence it is mandatory to plan programs for ...

results analysis by xrd showed 78.1% zno (sized 24 nm), 2.5% zn (sized 44.88 nm) and 4.8% zns (sized 12 nm) produced by p. stutzeri. the nanoparticles showed anti-bacterial activity against some of the gram positive and negative bacteria. in addition, the nanoparticles showed magnetic properties. the best condition for nano zinc production was at ph 7, in the light and at 37 °c. czcc gene with ...
