| Abstract | ||
| This study includes isolation and identification of different uropathogenes (bacteria- yeasts) collected from catheterized patients suffering from complicated urinary tract infections. Three hundred and fifty urine samples obtained by swabs from catheterized patients were identified for the presence of uropathogenes (bacteria and yeast). 221(63.13%) samples were obtained from females and 118 (33.71%) samples from male, 339(96.85%) sample were identified by culturing as a positive result, while 11(3.14%) sample were negative result. The 339 positive isolates include 303 (89.38%) bacterial isolates and 36 (10.61%) yeast isolates. Results of biochemical tests and Api 20 system for bacterial and yeast isolates reveals E.coli, Proteus spp, Klebseilla spp, Pseudomonas spp and Candida spp represented the main causative uropathogen infect urinary system and causing a complicated type of infection. The determination of bacterial and yeasts ability to form biofilm was carried out using test tube method , 306 isolates which represented (90.26%) were capable to form biofilm with differ in the thickness of formed layer. Pseudomonas spp formed the thicker biofilm followed by E.coli, Candida spp, Proteus spp, and Klebseilla spp. | ||
