Evidence for phage-mediated gene transfer among Pseudomonas aeruginosa strains on the phylloplane
(American Society for Microbiology, 1994-02)
As the use of genetically engineered microorganisms for agricultural tasks becomes more frequent, the ability of bacteria to exchange genetic material in the agricultural setting must be assessed. Transduction (bacterial ...
Characterization of the Pseudomonas aeruginosa recA analog and its protein product: rec-102 is a mutant allele of the P. aeruginosa PAO recA gene
(American Society for Microbiology, 1987-04)
We cloned a 2.3-kilobase-pair fragment of the Pseudomonas aeruginosa PAO chromosome which is capable of complementing recA mutations of Escherichia coli. The recA-complementing activity was further localized to a ...
Purification and properties of two deoxyribonucleases of Pseudomonas aeruginosa
(American Society for Microbiology, 1976-08)
A survey of the major deoxyribonucleases in Pseudomonas aeruginosa strain PAO was undertaken. Two activities predominated in Brij-58 lysates of this organism. These have been purified from contaminating nuclease activities, ...
Genetic diversity among Arthrobacter species collected across a heterogeneous series of terrestrial deep-subsurface sediments as determined on the basis of 16S rRNA and recA gene sequences
(American Society for Microbiology, 2000-08)
This study was undertaken in an effort to understand how the population structure of bacteria within terrestrial deep-subsurface environments correlates with the physical and chemical structure of their environment. ...
Prophage F116: Evidence for extrachromosomal location in Pseudomonas aeruginosa strain PAO
(American Society for Microbiology, 1977-06)
F116 is a temperate-generalized transducing phage of Pseudomonas aeruginosa. Genetic evidence leads to the conclusion that F116 prophage DNA is maintained extrachromosomally as a plasmid. Preliminary physical evidence is ...
Application of DNA probes to analysis of bacteriophage distribution patterns in the environment
(American Society for Microbiology, 1992-06)
Radiolabeled bacteriophage DNA probes have been used in this study to determine the distribution of Pseudomonas aeruginosa-infecting bacteriophages in natural samples of lake water, sediment, soil, and sewage. The sensitivity ...
Effects of norfloxacin on DNA metabolism in Pseudomonas aeruginosa
(American Society for Microbiology, 1986-01)
Norfloxacin is a quinolone (pyridonecarboxylic acid derivative) effective against Pseudomonas aeruginosa infections. We studied the effects of this drug on DNA metabolism in P. aeruginosa. Norfloxacin inhibits DNA replication ...
Frequency of F116-mediated transduction of Pseudomonas aeruginosa in a freshwater environment
(American Society for Microbiology, 1978-11)
Transduction of Pseudomonas aeruginosa streptomycin resistance by a generalized transducing phage, F116, was shown to occur during a 10-day incubation in a flow-through environmental test chamber suspended in a freshwater ...
Continuous culture model to examine factors that affect transduction among Pseudomonas aeruginosa strains in freshwater environments
(American Society for Microbiology, 1995-09)
Transduction among Pseudomonas aeruginosa strains was observed in continuous cultures operated under environmentally relevant generation times, cell densities, and phage-to-bacterium ratios, suggesting its importance as a ...
Transduction of linked chromosomal genes between Pseudomonas aeruginosa strains during incubation in situ in a freshwater habitat
(American Society for Microbiology, 1990-01)
Both transduction of single chromosomal loci and cotransduction of closely linked loci were observed between lysogenic and nonlysogenic strains of Pseudomonas aeruginosa in a freshwater habitat. Transductants were recovered ...
