Abstract

Background&Objective: Genital mycoplasmas can cause infection of the genitourinary tract. Thses organisms are associated with bacterial vaginosis, pelvic inflammatory disease, endometritis, cervicitis, Nongonococcal urethritis. Spontaneous abortion, premature birth, neonatal pneumonia and meningitis, and infertility. The aim of this study was to determine the ability of PCR method for diagnosis and identification of genital mycoplasma in culture negative samples taken from women suffering from bacterial vaginosis. Materials&Methods: 174 genital samples were taken from women suffering from bacterial vaginosis during January until December 2005. Two genital swabs were taken from each patient. One of them was cultured on the mycoplasma specific media for isolation of mycoplasma. The other swab was immersed in PBS buffer and frozen until DNA extraction. To detect the presence of mycoplasma and ureaplasma in genital DNA Samples: a 520-bp fragment of the 16S rRNA was amplified. The specific primers used for this purpose were: MGSO, UGSO, MY- ins. Results: From 174 samples, 71 samples (40.8%) were positive by culture for mycoplasma & ureaplasma. From 103 culture negative samples. According to PCR results, 14 samples (13.6%) were positive and 89 Samples (86.4%) were negative for mycoplasma and ureaplasma. Conclusion: This study showed that PCR method is more sensitive than culture for detection genital mycoplasma, Therefore PCR is a rapid, sensitive and easy method to detect genital mycoplasmas in urogenital swabs.

Abstract

Background and Objective: Mycoplasma Hominis is the smallest pathogenic bacteria, with no cell wall and free living organisms. It grows slowly and the conventional clinical microbiology techniques can not be applied due to difficulties in cultivation in particular slow growth incubation. This study was done to compare the culture and PCR methods for diagnosis of vaginal infection due to Mycoplasma Hominis. Methods: This laboratory test evaluation study was done on 150 patients with bacterial vaginosis and 50 healthy people with no infection as control, whom refereed to Imam Khomeini and Imam Zaman Hospitals in Tehran. Samples were collected in PPLO culture for growth and PBS to perform PCR method. Results: 35.3% and 76% of patients were positive using culture and PCR methods, respectively. Using PCR method 8% of control subjects was positive. There was no significant association between PCR method with abortion, place of residence and also level of educations. There was a significant association between the age (P<0.05), times of changing under wear cloths (P<0.05) and parity (P<0.05). Conclusion: PCR method is a more reliable technique to detect the vaginal infection due to Mycoplasma Hominis compared to culturing.
