从日本一头肉牛的阴道粘膜中分离到一株革兰氏染色阳性、厌氧性、不形成孢子、过氧化氢酶阴性、球形的细菌菌株，命名为BV 2 T。系统发育分析表明，该分离物与猪气球菌1821/02 T的16 S rRNA基因序列相似性高达92.9%，而与其他已知的气球菌属种的16 S rRNA基因序列相似性均低于92.7%。 DNA G+C含量为44.7mol%，在气球菌属物种中观察到的范围（37.5- 48.4mol%）内。脂肪酸组成以C18：1ω 9 c为主，与气球菌属的其它模式菌株相似。 基因型、表型和化学分类学分析的结果以及与所有已知的气球菌属成员的低程度DNA-DNA相关性表明，菌株BV 2 T代表气球菌属的一个新种，其名称为阴道气球菌（Aerococcus vaginalissp.）十一是建议。模式菌株为BV 2 T（= JCM 19163 T = DSM 27293 T）。 对猪气球菌、草绿气球菌、马尿气球菌、人尿气球菌、尿气球菌、克里斯滕森气球菌和血红气球菌的描述进行了修订。
A gram-stain-positive, facultatively anaerobic, non-spore-forming, catalase-negative, coccoid-shaped bacterial strain, designated BV2T, was isolated from the vaginal mucosa of a beef cow in Japan. Phylogenetic analysis showed that the isolate shared high 16S rRNA gene sequence similarity (92.9 %) withAerococcus suis1821/02Tand low similarity (<92.7 %) with any other recognized species of the genusAerococcus. The DNA G+C content was 44.7 mol%, which is within the range observed among species of the genusAerococcus(37.5–48.4 mol%). The major cellular fatty acid was C18 : 1ω9c, similar to other type strains of species of the genusAerococcus. The results of genotypic, phenotypic and chemotaxonomic analyses as well as the low degree of DNA–DNA relatedness with all recognized members of the genusAerococcusindicate that strain BV2Trepresents a novel species of the genusAerococcus, for which the nameAerococcus vaginalissp. nov. is proposed. The type strain is BV2T( = JCM 19163T= DSM 27293T). Emended descriptions ofAerococcus suis,Aerococcus viridans,Aerococcus urinaeequi,Aerococcus urinaehominis,Aerococcus urinae,Aerococcus christenseniiandAerococcus sanguinicolaare also presented.
