Across-sectional study was done on a total of 80 deep vaginal swabs (40 women with recurrent abortion and 40 pregnant women as control group) were collected from the September 2019 to the end of November 2019 from inpatients and outpatients women attended to Kirkuk general hospital to evaluate the prevalence of vaginitis due to bacterial causes and its relation with abortion in pregnant women. vaginal swabs were inoculated in bacterial media whose were prepared and sterilized according to the manufacturer's instruction. The prepared media were used for isolation, determination of the viable count, identification and susceptibility testing these media were carried out after being solidified. Swabs was inoculated onto MacConkey, nutrient and blood agars. Then the inoculated plates were incubated at 37°C for 24 hr. The included 40 women with recurrent miscarriage with age range (20-44 years), the study showed that 12 of 40 were within the age group 30-39 years and 12 were below 30 years with mean age (31.6 years) and their husbands mean age (35.43 years) and 65% of cases were rural. There was 60% of cases were with history of 3 miscarriage and 18.75% were 4 miscarriage. The study also revealed that majority of cases were parity 3-6. The study also indicated that majority of cases have history of miscarriage in the 1 st trimester in pregnancy. The study demonstrated that 55% of women with recurrent abortion have positive HVS culture comparing with 48% of pregnant women (control group). The study showed that 77.27% of women had aborted in the 1 st trimester of pregnancy and the lowest rate of abortion 3% was in the 3 rd trimester. The study revealed that highest rate of isolated bacteria from the HVS culture of aborted women was Gardenellavaginalis (36.36%), E. coli (27.27%) S. aureus (22.73%) and the higher rates of isolated bacteria from pregnant women were 50%% for E coli.
