Abstract

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 faecalis, Streptococcus sp. (B) group, Proteus mirabilis, P. 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.
