Plasmids of Pseudomonas cepacia strains of diverse origins.
Thirty-seven strains of Pseudomonas cepacia from clinical, pharmaceutical-industrial, and environmental origins were analyzed for the presence of plasmid DNA by a modification of the rapid alkaline extraction method of Birnboim (H. C. Birnboim, Methods Enzymol. 100:243-255, 1983). Plasmids were present in 31 strains (84%) from all sources, with no one source showing less than 75% plasmid carria...
متن کاملRole of porins in intrinsic antibiotic resistance of Pseudomonas cepacia.
The measured outer membrane permeability of Pseudomonas cepacia to the beta-lactam nitrocefin was low: approximately 10 times less than that of Escherichia coli and comparable to that of Pseudomonas aeruginosa. The purified P. cepacia porin demonstrated an average single channel conductance in 1 M KCl of 0.23 nS.
متن کاملChloramphenicol resistance in Pseudomonas cepacia because of decreased permeability.
The mechanism of chloramphenicol resistance was examined in a high-level-resistant isolate of Pseudomonas cepacia from a patient with cystic fibrosis. We investigated potential resistance mechanisms, including production of chloramphenicol acetyltransferase, ribosomal resistance, and decreased permeability. This strain (MIC, 200 micrograms/ml) had no detectable chloramphenicol acetyltransferase...
متن کاملPseudomonas cepacia in cystic fibrosis.
Pseudomonas cepacia, a Gram negative bacillus first described as a cause of soft rot in onions, is now recognised as an important opportunistic pathogen in altered hosts.' A distant relation of Pseudomonas aeruginosa, it is ubiquitous in the environment and frequently found in association with soil, water, and plants. It is a hardy organism, able to multiply in distilled water and survive in ma...
متن کاملPure Culture of Pseudomonas cepacia
A pure culture of Pseudomonas cepacia, designated AC1100, that can utilize 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) as its sole source of carbon and energy was isolated. An actively growing culture of AC1100 was able to degrade more than 97% of 2,4,5-T, present at 1 mg/ml, within 6 days as determined by chloride release, gas chromatographic, and spectrophotometric analyses. The ability of AC...
