This study involved the examination of bacteriuria according to the results of quantitative cultures in over 300 urine samples collected from patients admitted at El-Hussein University Hospital. The infection rate of both Escherichia coli and Klebsiella pneumoniawere found to be 26.92 and 11.54%; respectively. As the glucose and albumin concentration increased, the number of all infectious organisms greatly increased. Similarly, when creatinine concentration elevated up to 3.5 g/l, the infectious organisms (Enterobacter faecalisStreptococcus sp. (B) group, Proteus mirabilisP. aeruginosa,Enterobacter sp. and Citrobacter freundii) significantly increased. The effect of sodium chloride (NaCl), calcium oxalate (CaC2O4), magnesium chloride (MgCl2) and uric acid (C5H4N4O3) concentrations fluctuated according to the concentration used and the type of each infectious organism. Noracin was effective against all tested organisms.Acinetobacter sp. recorded 50% resistance to ampicillin while it was sensitive to all other tested antibiotics.


Key words: Bacteriuria, creatinine, antibiotics.
