ABSTRACT: Purpose
To date, molecular methods that circumvent the limitations of traditional culture methods have not been used to describe the vaginal microflora in India. Here, we compared culture and culture-independent molecular methods in characterizing the vaginal microbiota in Indian women.Methodology
Culture methods involved traditional cultivation on Rogosa and sheep blood agar, whereas culture-independent methods bypassed a culturing step by performing broadrange 16S rDNA PCR on DNA isolated directly from vaginal swabs.Results
A total of 13 women were included in the study, of which five were characterized as healthy, two were bacterial vaginosis intermediate and six were bacterial vaginosis positive according to Nugent scoring. Lactobacillus jensenii was detected most frequently when using culture methods. On the other hand, Lactobacillus iners, which was not detected by culture methods, was the most common Lactobacillus sp. detected using cultivation-independent methods.Conclusion
We found little overlap between the species found using cultivation-dependent and cultivation-independent methods. Rather, culture-dependent and culture-independent methods were found to be complementary in describing the vaginal microflora among South Indian women. Culture-independent methods were found to be superior in detecting clinically relevant vaginal flora.
