Nonconjugative plasmids encoding sulfanilamide resistance.

چکیده
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 megadaltons.

The population biology of bacterial plasmids: a priori conditions for the existence of mobilizable nonconjugative factors.
A mathematical model for the population dynamics of nonconjugative plasmids that can be mobilized by conjugative factors is presented. In the analysis of the properties of this model, primary consideration is given to the conditions under which these nonself-transmissible extrachromosomal elements could become established and would be maintained in bacterial populations. The results of this ana...
متن کاملComplete Genome Sequence of Phage-Like Plasmid pECOH89, Encoding CTX-M-15
A nonconjugative and nontypable plasmid of a clinical Escherichia coli isolate expressing resistance to extended-spectrum cephalosporins (ESCs) was isolated and sequenced. The plasmid pECOH89 contains a CTX-M-15 resistance cassette and comprises 111,741 bp, with strong homology to bacteriophage-like plasmids and to the Salmonella-specific bacteriophage SSU5.
متن کاملResistance 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 کاملProcessing of Nonconjugative Resistance Plasmids by Conjugation Nicking Enzyme of Staphylococci.
UNLABELLED Antimicrobial resistance in Staphylococcus aureus presents an increasing threat to human health. This resistance is often encoded on mobile plasmids, such as pSK41; however, the mechanism of transfer of these plasmids is not well understood. In this study, we first examine key protein-DNA interactions formed by the relaxase enzyme, NES, which initiates and terminates the transfer of ...
متن کاملGeneration of Helper Plasmids Encoding Mutant Adeno-associated Virus Type 2 Capsid Proteins with Increased Resistance against Proteasomal Degradation
Objective(s): Adeno-associated virus type 2 (AAV2) vectors are widely used for both experimental and clinical gene therapy. A recent research has shown that the performance of these vectors can be greatly improved by substitution of specific surface-exposed tyrosine residues with phenylalanines. In this study, a fast and simple method is presented to generate AAV2 vector helper plasmids encod...
