Effects of suspended particulates on the frequency of transduction among Pseudomonas aeruginosa in a freshwater environment
(American Society for Microbiology, 1995-04)
Transduction has been shown to play a significant role in the transfer of plasmid and chromosomal DNA in aquatic ecosystems. Such ecosystems contain a multitude of environmental factors, any one of which may influence the ...
Quantification of recA gene expression as an indicator of repair potential in marine bacterioplankton communities of Antarctica
(Inter Research, 2001-03-28)
Marine bacteria in surface waters must cope daily with the damaging effects of exposure to solar radiation (containing both UV-A and UV-B wavelengths), which produces lesions in their DNA. As the stratospheric ozone layer ...
Expression of the recA gene of Pseudomonas aeruginosa PAO is inducible by DNA-damaging agents
(American Society for Microbiology, 1988-05)
Western (immunoblot) analysis using Escherichia coli anti-RecA antiserum revealed that expression of the RecA protein of Pseudomonas aeruginosa PAO is induced upon exposure of the bacterium to UV irradiation or norfloxacin, ...
Mucoid conversion by phages of Pseudomonas aeruginosa strains from patients with cystic fibrosis
(American Society for Microbiology, 1984-05)
A total of 21 of 22 independent isolates of cystic fibrosis-associated Pseudomonas aeruginosa were found to be lysogenic for DNA-containing, complex capsid viruses. Several of the phages demonstrated the ability to select ...
Characterization of Pseudomonas aeruginosa mutants deficient in the establishment of lysogeny
(American Society for Microbiology, 1978-06)
Mutants of Pseudomonas aeruginosa with impaired ability to establish a lysogenic relationship with temperate bacteriophage (Les-) have been isolated. These les mutations map to two areas of the P. aeruginosa chromosomal ...
PaeExo IX: A unique deoxyribonuclease from Pseudomonas aeruginosa active in the presence of EDTA
(Oxford University Press, 1979)
A new deoxyribonuclease, PaeExo IX, has been purified to electrophoretic homogeneity from extracts of Pseudomonas aeruginosa strain PAO. This enzyme, which is active in the presence of EDTA, is equally efficient in hydrolyzing ...
Cloning and characterization of the cl repressor of Pseudomonas aeruginosa bacteriophage D3: A functional analog of phage lambda cI protein
(American Society for Microbiology, 1987-05)
We cloned the gene (cl) which encodes the repressor of vegetative function of Pseudomonas aeruginosa bacteriophage D3. The cloned gene was shown to inhibit plating of D3 and the induction of D3 lysogens by UV irradiation. ...
Potential for transduction of plasmids in a natural freshwater environment: Effect of plasmid donor concentration and a natural microbial community on transduction in Pseudomonas aeruginosa
(American Society for Microbiology, 1987-05)
Transduction of Pseudomonas aeruginosa plasmid Rmsl49 by the generalized transducing bacteriophage phi-DS1 was shown to occur during a 9-day incubation of environmental test chambers in a freshwater reservoir. Plasmid DNA ...
Further research on the classification of mucoid strains of Pseudomonas aeruginosa
(American Society for Microbiology, 1984-09)
Characterization of the Pseudomonas aeruginosa recA gene: The Les- phenotype
(American Society for Microbiology, 1988-02)
The Les- phenotype (lysogeny establishment deficient) is a pleiotropic effect of the lesB908 mutation of Pseudomonas aeruginosa PAO. lesB908-containing strains are also (i) deficient in general recombination, (ii) sensitive ...
