Use of ureidopenicillins for selection of plasmid vector transformants in Pseudomonas aeruginosa and Pseudomonas putida.

چکیده
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 carbenicillin, ampicillin, or ticarcillin required high concentrations of antibiotics and yielded backgrounds of spontaneous resistant mutants.

RSF1010 plasmid as a potentially useful vector in Pseudomonas species.
RSF1010 plasmid DNA was introduced into Pseudomonas putida and P. aeruginosa cells and maintained stably, suggesting the potential usefulness of this plasmid as a vector in Pseudomonas species. The number of copies of RSF1010 was 43 per chromosome equivalent in P. putida cells.
متن کاملUse of immunogenic moiety of Pseudomonas aeruginosa exotoxin A as a DNA vaccine in experimentally contaminated mice
Background: DNA immunization is an appropriate method to produce an immunological response. Pseudomonas aeruginosa produces exotoxin A which is highly cytotoxic for eukaryotic cells. Since domains II (translocation domain) and 1b of the toxin have antigenic qualities, so they could be useful candidates to protect against pseudomonas infections. Objectives: To evaluate if recombinant plasmid co...
متن کاملTransformation of Pseudomonas putida and Escherichia coli with plasmid-linked drug-resistance factor DNA.
Conditions optimal for the transformation of Pseudomonas putida and E. coli with a drug-resistance factor (RP 1) DNA, which specifies resistance to carbenicillin, tetracycline, kanamycin, and neomycin, are described. The transformants retain all the fertility, incompatibility, and drug-resistance characteristics present in the parent. Covalently-closed circular molecules of almost identical con...
متن کاملIsolation and characterization of Pseudomonas putida R-prime plasmids.
A number of enhanced chromosome mobilizing (ECM) plasmids derived from the wide host range plasmid R68 have been used to construct R-prime plasmids carrying a maximum of two map minutes of the Pseudomonas putida PPN chromosome, using Pseudomonas aeruginosa PAO as the recipient. For one ECM plasmid, pMO61, the ability to form R-primes did not correlate with the ability to mobilize chromosomes in...
