Sepsis is one of the most common causes of death worldwide both in hospitalized and non hospitalized patients. Vitek 2 is an automated system used for identification of bacterial isolates. These automated systems in bacteriology are very important for rapid and accurate detection of bacterias for effective diagnosis and treatment. Vitek 2 identified 18 genera of bacterias, 40 up to species level and 4 up to subspecies level. A total of 299 blood culture were tested, most common organism were gram negative bacteria (fermenters) followed by nonfermenters, gram-positive cocci and some of the bacterias which were isolated were uncommon and not detected by routine culture techniques. This retrospective study was carried out in order to study the incidence of bacterias isolated from blood cultures by Vitek 2.
