Urinary tract infection is one of the most common bacteria infections. The incidence of urinary tract infections in school age is more common in girls than in boys. Children have to be screened for asymptomatic bacteriuria before they reach to the state of renal damage. In our district no such study has been made to determine the prevalence of bacteriuria. Urine samples were collected from 642 school girls aged between 6-11 years, and were investigated by doing urine analysis and urine culture. 15 girls had significant bacteriuria, (>10^5 bacteria/ml). 11 children had pyuria (WBC>5), and 6 samples had both significant bacteriuria and pyuria. At the same time there were 5 cases with sterile pyuria. 6 girls had nitrite in their urine samples. All of the urine samples with positive nitrite test had significant bacteriuria. The study shows that there is a positive correlation between pyuria of nitrite and significant bacteriuria. Escherichia-coli is the most common microorganism in schoolgirls with significant bacteriuria. The incidence of screening bacteriuria was 2.3% which most of them were asymptomatic.

Urinary tract infection is common disease in pregnancy and most symptomatic infection with grate danger for fetus and mother’s. This study has been done to determine the prevalency of asymptomatic bacteriuria in pregnant women in Gorgan in 2000. Mid-stream urine from 900 pregnant women was obtained. Urine analysis and culture for all of them have been done and positive cultured (Isolated bacteria with 100000-colony count) was antibiogramed by Kerby Buer method. Out of 900 urine specimen 3.7% of samples had positive urinary tract infection. The common organism isolated was E.coli (33.3%), Coagulase negative, Staphylococci (30.3%) and Klebsiella (15.2%). There was not a significant correlation between age, pariety, pregnancy age, fresh urinary infection and asymptomatic bacteriuria but there was a significant and correlation kidney stone between bacteriuria. Anti-microbial sensitivity pattern demonstrates more sensitivity of strain with Amikacin and Gentamycin. Although prevalence of bacteriuria in this (3.7%) lower than other studies in this country but for their severe sequele. This phenomen should be taken into more consideration further investigation in other part of the country should be done to face the probable difficulties.

Background & Objective: Asymptomatic bacteriuria (ASB) is a significant problem during pregnancy because it can be developed into more severe infections that may have repercussions for the health of the mother and unborn child. The aim of this study was to assess relationship between asymptomatic bacteriuria and preeclampsia in Gorgan. Materials & Methods: This case control study performed on 150 preeclamptic women (Case group) compared with 150 healthy pregnant women (Control group) who hospitalized from 2002 to 2002 (Gravid, age and history of preeclampsia was matched with 2 group). The questionnaires and checklist was completed, urine analysis, and urine culture were performed. The data analyzed with SPSS software and statistical descriptive and analytic such as: T-student, U-Mann Whitney. Results: The risk of preeclampsia in pregnant women with ABS was 3.2 fold to healthy pregnant women (OR=3.22, CI 95% for OR=1.99, 5.21). Conclusion: Asymptomatic bacteriuria may predisposing factor to preeclampsia, we suggest screening of ASB in the 1st prenatal care and follow in 2nd and 3rd trimester of pregnancy o prevent the main side effect in pregnancy and the safety of mothers.
