Notes:

¹To determine how often the selected cultivable species have been reported in BV, a query in PubMed was performed by using a specific combination of keywords as “bacterial vaginosis” and “name of each species” (e.g., “Gardnerella”and “bacterial vaginosis”). We designated as “often described” those species referred in more than 50 articles in the last 25 years, while “commonly described” had at least 10 articles in the same period. Of note, the selected bacterial species used herein have been pointed out in several studies (Diop et al., 2019; Onderdonk, Delaney & Fichorova, 2016; Ravel et al., 2011) as potential microbial pathogens involved in BV development.

²The partial 16S ribosomal RNA gene sequences of Gardnerella sp. is downloadable from NCBI. UM: University of Minho, Portugal. In addition, the strain was phenotypically and genotypically characterized by Castro et al. (2020, 2015), Castro, Jefferson & Cerca (2018). It is of note that Gardnerella sp. UM241 did not match with any of the Gardnerella species described by Vaneechoutte and colleagues (Vaneechoutte et al., 2019) (i.e., G. vaginalis, G. piotii, G. leopoldii and G. swidsinskii), belonging to a yet unidentified Gardnerella species (Castro et al., 2020).
