Abstract: | Strain-specific circulating immunoglobulin G and/or M was detected by enzyme-linked immunosorbent assay and immunofluorescence test by using Formol-treated suspensions of Gardnerella vaginalis from 28 women with overt vaginitis but only three symptom-free subjects among 43 otherwise healthy women found to be colonized by G. vaginalis. Analogous but less stringent strain specificity patterns were elicited by immunization of BALB/c mice. |
