Abstract
Background: Asymptomatic bacteriuria is the presence of bacteria in the properly collected urine of a patient that has no signs and symptoms of urinary tract infection.
 Aim: This study was carried out to determine the incidence of asymptomatic bacteriuria in pregnant women in Saveetha medical college, Thandalam, Tamil Nadu.
 Materials and Methods: A total of 250 pregnant women attending antenatal clinic at civil hospital, Saveetha medical college, over a period of 3 months, with age groups between 18 to 30 years agreed to enter the study and were clinically evaluated. All these women were asked to submit clean catch midstream urine samples and it was examined under the microscope and by culture method.
 Results: A total of 250 pregnant women included in our study, with varying age groups between 18 to 30 years and the highest incidence was seen in between the 26 to 30 age group. Asymptomatic bacteriuria was seen in 27.2% of the pregnant women. The prevalence of Escherichia coli was among the most dominant organism, followed by Staphylococcus aureus ,klebsiella and proteus species.
 Conclusion: The study showed 27.2% of the pregnant women to have asymptomatic bacteriuria. This can be reduced by screening the mothers in first trimester and routine urine culture test must be carried out.
Highlights
Asymptomatic bacteriuria is the presence of bacteria in the properly collected urine sample of a patient who has no signs and symptoms of urinary tract infection
This can be reduced by screening the mothers in first trimester and routine urine culture test must be carried out
Screening test was not performed for pregnant women who are symptomatic with significant bacteriuria and the samples obtained were directly processed for culture and sensitivity.Bacterial growth of 105 CFU/ml or more is regarded as significant for infection
Summary
Asymptomatic bacteriuria is the presence of bacteria in the properly collected urine sample of a patient who has no signs and symptoms of urinary tract infection. Commonest organisms responsible for asymptomatic bacteriuria in pregnancy are Escherichia coli, followed by coagulase negative Staphylococcus species, Klebsiella species, Pseudomonas species, and Proteus species. These conditions begin in 6th week of gestation and peak during 22 to 24 weeks of gestation and this causes difficulty in passing urine. Materials and Methods: A total of 250 pregnant women attending antenatal clinic at civil hospital, Saveetha medical college, over a period of 3 months, with age groups between 18 to 30 years agreed to enter the study and were clinically evaluated All these women were asked to submit clean catch midstream urine samples and it was examined under the microscope and by culture method.
