Abstract
Abortion is an involuntary and spontaneous termination of pregnancy. Various factors can be involved in abortion, which many of them are currently unknown. Among these, bacterial infections have of particular importance. This study aimed to investigate the presence of Listeria monocytogenes and Brucella abortus in the vaginal secretions of women suffering from abortion by biochemical and molecular methods. In the present study, a total of 110 samples of vaginal secretions from women suffering from abortion were collected in 2019 in Isfahan, Iran. The samples were collected from patients by gynecology, obstetrics, and infertility properly. Then, the antibiotic sensitivity test on bacterial isolates was done using the standard antibiogram method. The molecular detection of bacteria was done by performing PCR reaction using specific primers designed for 16S rRNA gene amplification in L.monocytogenes and B. abortus. Based on the results, a total of 110 isolates of bacteria were obtained in the present study from women with and without abortion. Among the isolates, 3 of them belonged to L. monocytogenes (10.3%) and 1 isolate belonged to B. abortus (3.4%). B. abortus was sensitive to all antibiotics used, and out of 3 L. monocytogenes isolates, one of them was resistant to tetracycline, ampicillin, and gentamicin antibiotics. The results of molecular identification showed that the trying to design the species-specific primer for amplifying the 16S rRNA gene by PCR assay may be a fast, low-cost, and reliable tool to screen for bacterial agents involved in abortion, which need to more study in population. The high prevalence of L. monocytogenes in the vaginal secretions of women suffering from abortion is cause for concern and should be taken into consideration by the treatment staff.
