Abstract
A number of 265 sample taken from patients in this hospital and other patients who consult the clinics in it had been gathered from TIKRIT General Educational Hospital . . The samples were taken for the patients whom doctors thought them infected with Urinary Tract Infections , Wound & Burn Infections and Mid- ear Infections for males and females in varied ages during the period from the beginning of December 2006 till the beginning of March 2007. Isolates diagnosed depending on of the morphological criteria cultural and morphological and biochemical test and API Staph Ident system test. The results revealed 60% Coagulase negative Staphylococci , which shows 27 isolates (45% ) regards S. epidermidis , 13 isolates (21.66%) S. saprophyticus , 10 isolates (16.67%) S. xylosus , 3 isolates (5%) S. lentus , two isolates (3.33%) S. heamolyticus and one isolate (1.67%) S. simulans and other one isolate of S. hominis . The research made use of a number of main tests in order to archive the purpose of this study according to the planned goals, some of which are the virulence factors in Coagulase negative Staphylococci is included DNase, Urease, Lipase, Lecithinase, Alkaline phosphatase. The results revealed the ability of (67.5%) isolates of this study to produce Alkaline phosphatase enzyme , the results also revealed that 46.6% of isolates to produce Urease enzyme, also it shows (27.5%) of isolates to produce Lecithinase enzyme, and the ability of (19.16%) to produce Lipase enzyme , while (22.5%) of isolates were capable of producing DNase enzyme.
