                Abstract  
           The study included collect and examine 50 samples of urine and blood  from catheter – associated urinary tract outpatients , in addition to 12 samples from healthy persons as control . It is show the infection rate of urinary tract is 22 ( 44% ) and it was found that infection by Gram negative bacteria was more dominant in those patients : Escherichia  coli was isolated in a high percent ( 27.2 % )  , Pseudomonas aeruginosa ( 22.73 % ) Klebsiella pneumoniae ( 18.2 % ) and Proteus vulgaris ( 9.11 % ) , one mixed infection by Escherichia coli + Pseudomonas  aeruginosa (4.5% ) while the isolated rate by Gram positive bacteria was low as : Staphylococcus  aureus ( 9.11% )  then Staphylococcus epidemidis  ( 4.5% ) and one infection by Candida albicans  ( 4.5%) . The result of antibiotics sensitivity test showed that the most of pathogenic bacteria were highly sensitive to Amikasin , Ciprofloxacin and Imipenem  while resistant to Amoxicillin , Ampicillin , Trimethoprim and Gentamicin .  It show that  concentration rate of immunoglobulin (IgG ) in serum of mostly patients was high about 1967.2 mg / dl in comparison to healthy persons (  780.1 mg / dl ) .
