Resistance plasmids of Pseudomonas aeruginosa: change from conjugative to nonconjugative in a hospital population.
Properties of a population of carbenicillin- and gentamicin-resistant, tobramycin-susceptible Pseudomonas aeruginosa at Veteran's Administration Hospital, Cincinnati, Ohio, have been followed during a 16-month period. As originally described, the strains were isolated from patients with urinary tract colonizations and were predominantly Parke-Davis immunotype 7. For the majority of these organi...
متن کاملPlasmids and transposable elements in Salmonella wien.
The plasmids from six clinical strains of Salmonella wien have been characterized. All the S. wien strains were found to carry three types of plasmids: an IncFI R-Tc Cm Km Ap (resistance to tetracycline, chloramphenicol, kanamycin, and ampicillin) plasmid, either conjugative or nonconjugative, of large size (90 to 100 megadaltons); an R-Ap Su Sm (resistance to ampicillin, sulfonamide, and strep...
متن کاملNonconjugative plasmids encoding sulfanilamide resistance.
Nonconjugative plasmids encoding sulfanilamide (Sa) resistance were demonstrated at a high frequency in Shigella and Escherichia coli strains resistant to sulfanilamide. These Sa plasmids were all compatible with the standard plasmids used in compatibility testing. The sizes of seven Sa plasmids were measured by electron microscopy and ranged from 1.79 to 2.08 mum, corresponding to 3.5 to 3.9 m...
متن کاملCharacterization of a translocation unit encoding resistance to mercuric ions that occurs on a nonconjugative plasmid in Pseudomonas aeruginosa.
The nonconjugative plasmid, pVS1, has a molecular weight of 18.5 X 10(6) and confers resistance to sulfonamides and to mercuric ions. In Pseudomonas aeruginosa PAO, the transfer can be mobilized by a variety of conjugative plasmids, and the process does not require a functional recombination system in the donor. Hybrid plasmids that arise by the relocation of the mer gene onto the mobilizing pl...
متن کاملCharacteristics of conjugative R-plasmids from pathogenic avian Escherichia coli.
Three of four virulent avian Escherichia coli isolates transferred a single large molecular-weight R-plasmid to two recipient E. coli strains. Antibiotic resistances transferred included streptomycin (two isolates) and streptomycin-tetracycline-sulfa (one isolate). Production of colicin and siderophores, complement resistance, and embryo lethality present in the virulent isolates were not trans...
