The vaginal microbiota is known to harbor over 250 species of bacteria such as Actinomyces, Bacteroides, Enterobacter, Mollicutes, Proteobacteria, Salmonella, and Streptococcus (2). In 1892, Albert Döderlein became the first researcher to explain the significance of lactic acid-producing bacteria in the vaginal microbiome (2). Since then, research has evolved to determine the most prominent species found in the vagina, the most common disturbance of the vaginal microbiome, the varying microbiota types, how the microbiota affects childbirth, and so much more. In normal function, the vaginal microbiota contains a mixture and balance of bacteria such as those previously mentioned. Although, comprehensive surveys of the vaginal microbiome have proved that Lactobacillus species are among the dominant vaginal bacterial species in a large proportion of women (3).
Lactobacillus
‘’Lactobacilli’’ are gram-positive, rod-shaped, non-spore-forming bacteria that grow well in microaerophilic conditions (4). As a gram-positive firmicute, ‘’Lactobacilli’’ have a thick cell wall with a cell envelope consisting of glycosyl chains, an s-layer, peptidoglycan with teichoic acids, and a cell membrane containing membrane specific proteins.
