Salmonella are widely distributed and can be survived in contaminated food and water which are considered a real health hazard. The genus Salmonella that associated with human infection cause food-borne and water-borne by consumption of contaminated meat, milk, eggs and water. These organisms grow on mainly nutrient media, the growth of most Salmonella strains require minimal media containing sulphate phosphate, ammonium salt for nitrogen, as well as glucose as a source of energy and Carbone. Salmonella infections are commonly increased in low income countries. The aim of this review is to review the characteristics of Salmonella, the virulence properties of Salmonella, pathogenesis and Salmonella infection.
