PURPOSE: We aimed to investigate the detection of nanobacteria (NB) from expressed prostatic secretions (EPS) in patients with category III chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and from vaginal swabs in patients with vaginitis by reverse transcriptase polymerase chain reaction (RT-PCR) and to evaluate the association between NB and Neisseria gonorrhea, Chlamydia trachomatis, Ureaplasma urealyticum (U. urealyticum), Mycoplasma hominis, Trichomonas vaginalis, and Mycoplasma genitalium.
MATERIALS AND METHODS: A group of 11 men attending a specialized CP/CPPS clinic and a group of 157 women who reported symptoms of lower genital tract infection were enrolled in this study. NB were detected by RT-PCR. A Seeplex Sexually Transmitted Disease Detection assay (Seegene Inc., Seoul, Korea) was used that could detect DNA for 6 types of sexually transmitted pathogens.
RESULTS: In EPS samples, the detection rate of NB in patients with CP/CPPS was 9.1%, and 9 (5.7%) of 157 vaginitis patients showed positive results in RT-PCR for NB in vaginal swabs. Associations observed among the 7 microorganisms included 6 (54.5%) patients who tested positive on EPS and 75 (47.8%) patients who tested positive on vaginal swabs. Five patients with vaginitis were found to have monoinfection of NB (6.7%).
CONCLUSIONS: We found that conventional RT-PCR for NB was rapid, simple, low in cost, and easily available for the detection of NB, and that NB may be a possible etiological factor for vaginitis and CP/CPPS. The prevalence of U. urealyticum among the four patients with NB coinfection was 75%; the presence of U. urealyticum might therefore raise suspicion for nanobacterial infection.
