Plasmid Pattern of Biofilm Producing Proteus mirabilis and Proteus vulgaris among Clinical Isolates in Kerman University Hospitals during 2011-2012

Background & Aims: Emergence of biofilm producing Proteus strains created a serious problem in the treatment of catheter-associated urinary tract infections. The aim of this research was to study biofilm production and plasmid pattern of proteus strains associated with Urinary tract infection. Methods: A total of 88 strains of Proteus were isolated from samples collected in hospitals of Kerman/...

Plasmid-mediated carbencillin hydrolyzing beta-lactamases of Proteus mirabilis.

Since ABRAHAM and CHAIN') reported the production of beta((l)-lactamase by Escherichia coli, penicillinases have been shown to play an important role in the resistance of organisms against (3lactam antibiotics2.3). In many cases, the 46lactamases of Gram-negative bacteria have been shown to be mediated by R plasmids'), in contrast to chromosomally encoded drug resistance'). 46-Lactamases of Pro...

Transduction of R factors in Proteus mirabilis and P. rettgeri.

Phage 34 transduces some R factors to Proteus mirabilis strain 13. These transductants can transmit the R factor by conjugation. Transduction frequencies vary from I x I ~-~/plaque-forming unit (p.f.u.) adsorbed (higher than .chromosomal marker transduction) to 5 x Io-8/p.f.u. adsorbed. Transduced drug resistance markers of other R factors were detected only in the presence of resident$factors ...

R-factor-mediated resistance to tetracycline in Proteus mirabilis.

The expression of R-factor-mediated resistance to tetracycline has been compared in Proteus mirabilis and Escherichia coli. Resistance to a range of concentrations of tetracycline was significantly lower in P. mirabilis than in E. coli in both induced and repressed states. Indirect evidence showed that conditions which result in a marked increase in the level of resistance of P. mirabilis harbo...

Transduction of R factors by a Proteus mirabilis bacteriophage.

A transducing phage, designated phim, was isolated from a lysogenic strain of Proteus mirabilis and was characterized with respect to its physical and genetic properties. The phage contains double-stranded deoxyribonucleic acid (DNA) with an S(20,w) degrees of 29 which corresponds to a molecular weight of 24 x 10(6) daltons. The base composition of phim DNA was estimated to be 40% guanine plus ...
