Abstract
Preterm labour was known as occurrence of delivery before completing 37 weeks of gestation, through which reduction in normal vaginal flora will occur specially lactobacilli in addition to change of pH, which may lead to increases of some aerobic bacteria such Gardnerella vaginalis , so this study was conducted to assess bacterial vaginosis rate among women with preterm labour. From the period of 1st of December2008 to 31th 2009 retrospective study was carried on in Suliamania teaching and Azadi teaching Hospitals. Seventy five women were enrolled in the study, their age ranged from 15 to 45 years. For each patient special questionnaire form was filled ,also for each high vaginal swab(HVS) was tested for color,pH,whiff test and Clue cells in addition to cultivation of HVS & urine for detecting other bacterial isolates. Women with polyhydraminos, multiple pregnancy, cervical incompetence, malformed uterine & drug addict were discharged from the study. The results were revealed the all rate of infection 76.67 % which included bacterial infection 42.67%(high rate 16.07 % with Escherichia coli and the low rate was with Proteus species),followed by 33.33 %,18.67 % & 8 % for, Gardnerella vaginalis, Candiada albicans & Trichomonas vaginalis respectively P<0.05.Gardnerella vaginalis was seen in 21 samples as pure cases with the rate 84 % mostly associated with clue cells & pH ranged from 6 to 8 with the rate of 26.42 %, Moblincus species rate was 9.12 %. Relationship between patient residency, age in regard bacterial vaginosis & other microorganisms’ distribution were not statistically significant. History of vaginal discharge, disparunia, rupture membrane & vaginal itching in association to microbial distribution were significant P<0.05.
