Plasmidic content of certain virulence factors of Escherichia coli bacteria isolated from different organisms in Kirkuk City

The study included isolation and diagnosis of Escherichia coli from clinical animal sources (humans, cows, sheep, birds, chickens, fish, gecko). It collected 275 samples distributed to 125 taken urine 150 other organisms with 25 per organism. isolates used in the were diagnosed on appearance, microscopy, chemical tests, as well confirmatory testing isolations through use Api 20 E tape, where 41 E. bacteria obtained source 89 organisms. Some fertility factors bacterial studied, all found be Capsule productive, while non-Hemolysin enzymes, Extended Spectrum β-lactamase enzymes 41% (53/130), isolates' ability form biofilm was investigated producers 60% (77/130). Three selected for each their plasmid content, Electrically phased isolators agarose gels have shown a different variety content.
