Assessment of Bacterial Isolates in Urinary Tract Infection among Pregnant Women

Abstract

Background: To assess bacterial isolates in urinary tract infection among pregnant women. Material and Methods: One hundred thirty antenatal women between 12-16 weeks of gestation were enrolled. A clean catch mid-stream urine specimen was collected from all subjects. Colony count of 100 or more equivalent to ≥ 105 CFU/ml was considered as significant bacteriuria. Results: Age group 18- 21 years comprised of 60 subjects, 22- 25 years had 39, 26- 29 years had 25 and 30- 33 years had 6 subjects. The difference was significant (P<0.05). Asymptomatic bacteriuria (ABU) was seen in 30 and symptomatic bacteriuria in 55 subjects. The prevalence found to be 65.3%. The difference was significant (P< 0.05). Bacterial isolates were, Staphylococcus aureus was 35% and 42%, Escherichia coli was 35% and 30%, Streptococcus Spp. was 15% and 22%, Pseudomonas Spp. was 10% and 4% and Acinetobacter Spp. was 5% and 2% in ABU and symptomatic bacteriuria patients.
Conclusion: Urinary tract infection is quite common in pregnancy. Common isolates seen are Staphylococcus aureus, Escherichia coli, Streptococcus spp., pseudomonas spp., candida spp. and Acinetobacter spp.
