Assessment the relationship of Antibiotic profile and virulence factors in Klebsiella pneumoniae

Background: Nosocomial infections are frequently caused by Klebsiella pneumoniae. The great majority of antibiotics no longer effective against K. goal this study was to see if there a link between antibiotic resistance and the ability produce biofilms in pneumoniae strains isolated from UTI patients Iraq. Methods: A total 85 non-duplicate clinical samples urine, blood, sputum, wound swabs, Catheters swab endotracheal tubes which were collected over course year. Identification isolate done analyzing colony morphology, microscopic examination, performing biochemical testing. Testing susceptibility CLSI Kirby–Bauer disk difusion method, biofilm-producing crystal violate microtiter plate method as adherence quantitative assays. Virulence tests carried out, including: string test, haemagglutination, yeast agglutination for all samples. Results: isolates able generate (78 isolates, 91.8 %).
