Asymptomatic Urinary Tract Infection in Pregnant Women

Background and objectives: urinary tract infection is one of the most common bacterialinfections in the human population, and more frequent infection during pregnancy. with noticeto this point that most of urinary tract infections during pregnancy are asymptomatic, they couldlead to serious complications such as prematurity, low-birth weight, hypertension, and higher fetalmortality rates if untreated. this study was aimed to determine the prevalence of asymptomaticbacteriuria, bacterial agents and their antibiotic susceptibility pattern in pregnant women attendingsemnan public health centers during 2007-8.patients and methods: in this descriptive cross sectional study, pregnant women attendingsemnan public health centers during may 2007 and june 2008 were investigated. clean catch midstream urine samples were collected and cultured on eosin metylene blue agar and blood agar bycalibrated loop method. suspected colonies were identified, antibiotic susceptibility test was done.results: of 297 samples, 10 (3.3%) were positive for asymptomatic urinary tract infection. thedominant bacterial isolate was escherichia coli (70%). the antibiotic susceptibility was observedto ciprofloxacin, ceftazidime and cefotaxime (80%), the most resistance was amoxicillin- clavulanicacid (90%).conclusion: frequency of asymptomatic uti in pregnant women in this study is significantlylower than similar studies. antibiotic susceptibility rate to using antibiotics do not show significantdifferences with most other studies.
