Abstract

Aim & Objective: Determination of prevalence, bacterial profile and antibiotic sensitivity of microorganisms responsible for asymptomatic UTI during pregnancy. Methodology: The type of study is cross-sectional, Prospective type, was conducted at the PUMHS for Women Nawabshah (SBA) after approval from the Ethical Review Committee and the duration was 2 years from 1st Jan 2021-31st Dec 2022. Samples were collected by non-probability- convenient method from all pregnant women without any clinical complaints attending the Outpatient Department of Gynecology and Obstetrics PUMHS Hospital Nawabshah. The midstream urine collected by clean catch method in sterile containers was processed for DR of urine including physical, chemical, and microscopic examination. After the urine detailed report, the samples were sent for, culture by using the following media, blood, Macconkey’s, and CLED agar. Growth-positive samples were proceeding for gram staining, biochemical tests, and antibiotic sensitivity reports according to world standard methods for confirmation. Results: Out of 477 patients 96 (20%) were positive for ASB, with the mean age of the patient being 29.32±5.74 The most common microorganisms found in the study were E.coli 67 (69.7.%), followed by Klebisella in 4(4%), proteus 9(9%), pseudomonas 8(8.3%), staphylococcus aureus 2(2%), staphylococcus saprophyticus in 4(4%), streptococcus pyogen 2(2%). There was 100% sensitivity found for all isolated microorganisms following culture examination to following antibiotics: Ciprofloxacin, Cefuroxime, Imepenem, Ceftriaxone Amikacin, Meropenem, and Piperacillin-tazobactam; however, 52% and 45% sensitivity of E.coli and 100% sensitivity of streptococci were present for amoxicillin-clavulanic acid and ampicillin respectively. Conclusion: A rising number of silent antenatal bacteriuria was observed in younger age women with severe maternal and fetal complications in advanced stages of pregnancy and thereafter. It is therefore suggested to routinely perform urine cultures for every suspected pregnant lady during advanced antenatal visits to diagnose and properly treat the asymptomatic bacteriuria in terms of avoiding antibiotic resistance and materno-fetal complications in the near future.
