A total of 525 urine samples, 295(56.2 %) from females and 230 (43.8%) from males were collected at Al-Hussain Teaching Hospital, Nassiyria, and sub¬jected to bacteriological investigation during the period March to August, 2008 . Positive monomicrobial cul¬tures were isolated from 326(62%) of the total specimens distributed in 211(64.7%) females and 115 (35.3 %) males. Gram-negative aerobic and facultative anaerobic rods accounted for 168 (51.5 %) and the predominant species was E. coli, while Gram-positive bacterial counts were 152 (46.6 %) and Staphylococci was the predominant one .The remain 6 (1.8 %) were Candida albicans. Amikacin and nitrofurantoin were active against both Gram +ve and Gram-ve isolates. The percentage of Gram +ve cocci resistant to vancomycin reached 13.8% . In addition to that, Gram +ve isolates were sensitive to ciprofloxacin and cefotaxime. Static biofilm assay results showed that 299 (94%) from 318 clinical isolates produce biofilm In Vitro measured at wave length 590 nm. All of S. aureus , Streptococcus spp, Klebsiella spp and Enterobacter spp produce biofilm (100%). Whereas 95.5% E. coli produce biofilm.
