background: salmonellosis is one of the most importantzoonotic diseases throughout the world. objectives: thepurpose of this study was to characterize a large collection ofsalmonella isolates from different poultry sources in iran.methods: a total of 123 salmonella isolates from differentpoultry sources were subjected to drug susceptibility test,hemolysin production, motility test, and plasmid ...

Plasmid genotypes of root nodulating rhizobial isolates of Sesbania, sampled from six ecologically distinct habitats, were characterized. Plasmid profile analysis revealed nine different plasmid types having molecular masses ranging from 30 to 300 MDa, distributed among six profile types that grouped the isolates into six plasmid classes. The six plasmid profiles were diverged from each other a...

the species of pseudomonas genus show different levels of resistance to soil's heavy metals pollution. since, there exists is a relationship between heavy metal resistance and plasmid profile of bacteria, in this study, plasmid profile of plant growth promoting rhizobacteria (pgpr) pseudomonas fluorescence isolates were studied in the presence of cadmium and zinc. the bacteria were initial...

Plasmid profile analysis (PP) is a method of determining a number and size of plasmids in bacterial isolates. When using plasmid profile analysis in determining epidemiological strain for evaluation of this method, it is necessary to compare epidemiological strains with non-epidemiological ones isolated in the same period of time. Plasmid profile determination is performed by lysis of bacterial...

In 1988, a new plasmid profile was observed for Vibrio salmonicida isolated from cod (Gadus morhua) and Atlantic salmon (Salmo salar) in fish farms in northern Norway. This new plasmid profile, which consisted of plasmids of 61, 21, 3.4, and 2.8 megadaltons, is 1 of 11 plasmid profiles which have so far been observed for V. salmonicida. Plasmid profiling and plasmid DNA hybridization were used ...

The genome of the fish pathogen Aeromonas salmonicida subsp salmonicida harbors a large number of insertion sequences (ISs), many of which are located on plasmids. In the present study, we analyzed the small plasmid profile of A. salmonicida strains to identify evidences of plasmid alterations. Ten out of 78 strains analyzed displayed an unconventional plasmid profile. However the HER1104 strai...

Background: The importance of plasmid-encoded Extended Spectrum Beta Lactamase (ESBL) organisms in the dissemination multi-drug resistance and complicated infections are contributory factors to treatment failure. Despite these, there is a paucity information regarding plasmid-borne associated infection from primary sources including cockroaches while studies correlating total protein ESBL also ...

This study determined the plasmid profile and antibiotic resistance patterns of extended spectrum beta lactamases producing Pseudomonas aeruginosa expressing Amp C beta lactamase enzyme using standard procedures. Results obtained revealed that 32 (43.2%) had one plasmid, 37(50%) had two plasmids while the remaining five carried three plasmids each. The plasmid sizes ranged from 800bp to 25000-b...
