Bacterial Profile and Antimicrobial Susceptibility Pattern in Pregnant Women with Urinary Tract Infection Attending the Department of OBG in a Tertiary Care Hospital

Urinary tract infections(UTI) are the most common bacterial infections among women in both pregnant and non pregnant states, among which asymptomatic bacteriuria is the commonest. Symptomatic bacteriuria includes cystitis and pyelonephritis. UTI is a disease of multiple etiology and is known for its recurrence despite the treatment. Every woman has a 20% life time risk of developing UTI. A sincere effort has been put to understand the local epidemiology of the organism and its susceptibility pattern so as to initiate an effective treatment. 1. To study the bacterial isolates of Urinary tract infection in pregnant women. 2. To study the antibiogram of the bacterial isolates. The study was conducted among 100 pregnant women who attended Obstetrics and Gynecology (OBG) outpatient department at a tertiary care centre, Bangalore, India, over a period of six months. For isolating the bacteria, standard conventional method of isolation and identification was followed. Antibiotic susceptibility of the isolates were determined using Kirby Bauer disk diffusion method. The data was analyzed using standard statistical package. Majority of the isolates were Escherichia coli (33.98%) followed by Klebsiella species (19.41%), Coagulase negative staphylococcus (16.50%) and Enterococcus fecalis(13.59%), Acinetobacter species(7.76%), Staphylococcus aureus (3.88%), Pseudomonas and Enterobacter species were 1.9% each. Proteus being the least(0.97%). The isolates were sensitive to Aminoglycosides (97.08%) and Nitrofurantoin (97.08%). The study suggests that the common etiological agent for UTI in pregnant women was Escherichia coli and was sensitive to Aminoglycosides and Nitrofurantoin.
