Abstract
Vaginosis is a dysbiotic condition of the vaginal cavity that has deleterious effects during pregnancy. The role of methanogens in this disease is unknown since current methods of investigation are not appropriate for the search of methanogens. We prospectively investigated the presence of methanogens in vaginal specimens collected from 33 women thereafter diagnosed with bacterial vaginosis and 92 women thereafter diagnosed without bacterial vaginosis (control group) by direct microscopic examination and fluorescent in situ hybridization, PCR-sequencing, and real-time PCR and isolation and culture. These investigations found only one methanogen, Methanobrevibacter smithii, exclusively in 97% bacterial vaginosis specimens and in two intermediate microbiota specimens. M. smithii was detected microscopically in 2/20 specimens analyzed, by PCR-based observations in 34/125 specimens with 99% sequence similarity with the reference 16S rRNA and mcrA gene sequences and was cultured in 9/40 specimens. These data suggest that the detection of M. smithii could be used as a biomarker for the laboratory diagnosis of bacterial vaginosis.
