Background and Objective: Pseudomonas aeruginosa is a causative agent of nosocomial infections. Metallo-beta-lactamases (MBLs) are considered among the most crucial resistant agents of Pseudomonas aeruginosa to carbapenem. Because of the important role of carbapenemes in the treatment of Pseudomonas infections, in this study, the Pseudomonas aeruginosa producing metallo-beta-lactamases were inv...
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 ...
background and objectives: lipases are particularly important due to the fact that they specifically hydrolyze acyl glycerol, oils and greases, which is of great interest for different industrial applications. materialst and methods : in this study, several lipase-producing bacteria were isolated from wastewater of an oil processing plant. the strain possessing the highest lipase activity was i...
The genus Pseudomonas has been reported to be a genetically and metabolically diverse bacterial group (Anzai et al., 2000; Kersters et al., 1996; Moore et al., 1996). Pseudomonas species of the rRNA-DNA similarity group I have been previously stated by Palleroni (1984) to form the genus Pseudomonas (sensu stricto) within the g subclass of the Proteobacteria. The formerly Pseudomonas species of ...
In the present study, a multiple approach was used to characterize Malpighia punicifolia extract and to evaluate its inhibitory activity against several meat spoilage bacteria. First, volatile fraction, vitamins and phenolic compounds of the extract obtained by supercritical fluid extraction were determined by GC-MS and HPLC. Then, the antimicrobial action of the extract was in vitro evaluated ...
Primers corresponding to conserved bacterial repetitive of BOX elements were used to show that BOX-DNA sequences are widely distributed in phosphate solubilizing Pseudomonas strains. Phosphate solubilizing Pseudomonas was isolated from oil palm fields (tropical soil) in Malaysia. BOX elements were used to generate genomic fingerprints of a variety of Pseudomonas isolates to identify strains tha...
