Pseudomonas aeruginosa is a Gram-negative, aerobic rod belonging to the bacterial family Pseudomonadaceae. The family includes other genera, which, together with certain other organisms, constitute the bacteria informally known as pseudomonads. These bacteria are common inhabitants of soil and water. They occur regularly on the surfaces of plants and occassionally on the surfaces of animals. Th...

The population dynamics of pseudomonads in gilt-head sea bream Mediterranean fish (Sparus aurata) stored under different conditions were studied. Phenotypic analysis and sodium dodecyl sulfate-polyacrylamide gel electrophoresis of whole-cell proteins were performed to identify a total of 106 Pseudomonas strains isolated from S. aurata stored under different temperatures (at 0, 10, and 20 degree...

The refractory nature of Pseudomonas infections to chemotherapy reflects its ability to rapidly acquire resistance and adapt to hostile environment. In order to keep eye on changing trends in susceptibility patterns of Pseudomonas sp. and to modify therapeutic choices, a retrospective study was carried out. Samples for culture and sensitivity testing were screened for presence of Pseudomonas sp...

Objective: To investigate infection distribution of Pseudomonas aeruginosa on burned patients in our hospital as well as its drug resistance in order to provide reference of clinical use of antibiotics. Methods: Statistically analysed 481 Pseudomonas aeruginosa and their drug sensitive test results from burned patients who were sent to hospital from January 2004 to December 2006. Results: In ou...

OBJECTIVE This study was pursued as an extension of a randomized clinical investigation of neonatal screening for cystic fibrosis (CF). The project included assessment of respiratory secretion cultures for pathogens associated with CF. The objective was to determine whether patients diagnosed through neonatal screening and treated in early infancy were more likely to become colonized with Pseud...

Pseudomonas aeruginosa exotoxin A (PA), a potent protein synthesis inhibitor, was found to be a weak T-cell mitogen for murine splenocytes. Maximal stimulation of [3H]thymidine incorporation was obtained with 10 to 100 ng of toxin per ml following a 4-day induction. PA was also shown to be a polyclonal activator of cytolytic T lymphocytes (CTL), effective against concanavalin A-treated target c...

Pseudomonas fluorescens strains that produce the polyketide antibiotic 2,4-diacetylphloroglucinol (2,4-DAPG) are among the most effective rhizobacteria that suppress root and crown rots, wilts, and damping-off diseases of a variety of crops, and they play a key role in the natural suppressiveness of some soils to certain soilborne pathogens. Root colonization by 2,4-DAPG-producing P. fluorescen...

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...
