Lactobacilli are dominant bacteria of the vaginal flora. Lactobacillus-containing probiotics products are used for the treatement and profylaxis of bacterial urogenital infections. This work is focused on DNA identification and species identification of probiotic bacteria in 5 different vaginal tablets using molecular-genetic methods. Total DNA isolated from complex matrix of vaginal tablets was used for amplification in polymerase chain reaction. DNA was isolated from crude cell lysates by magnetic particles P(HEMA-co-GMA) and by method of phenol extraction. Identification of species of probiotic bacteria was verified using genus-specific and species-specific PCRs. Results of bacterial identification obtained by PCR were compared with declared specification given by producers. Bacteria of genus Lactobacillus were proved in all tablets whereus species identification was in accordance with the stated composition in 1 tablet only.
