Detection of Some Virulence Factors of Aeromonas hydrophila Bacteria That Contaminated Tigris

The aim of the study is to investigate the bacteria Aeromonas hydrophila of the most important contaminated of the Tigris river pathogenic to humans and other living organisms and Detection of some virulence factors. In this study, we were obtained (45) isolates of Aeromonas hydrophila bacteria isolated from (100) sample of Tigres river water and from different sites, from Baghdad to it's point contact with Diyala river. Isolates were identifed by Vitek 2 system by biochemical tests in addition to bacteriology diagnosis by observing morphological and microscopic features of colones and results were showed the ability of all isolates(100%) to produce protease, while 40 isolates (88.8%), 34 isolates (75.5%) and 31 isolates (68.8%) produced β-hemolysin, Phospholipase and DNase respectively in addition to it's Bioflm production at 100%.
