Genus: Gemella
Lineage: Bacteria;Bacillota;Bacilli;Caryophanales;Gemellaceae;Gemella
Overview: There are five species of Gemella in the human oral microbiome:
G. bergeri, G. haemolysans, G. morbillorum, G. sanguinis, and G. sp. HMT 928.
Ecological role/importance in health and disease: Gemella species reach their highest relative abundance on the buccal mucosa and keratinized gingiva, where G. haemolysans makes up 5-8% of the community. G. sanguinis makes up about 1% of the tongue dorsum microbiota and G. haemolysans and G. morbillorum together make up 0.5-1% of dental plaque in healthy individuals. Gemella species can be opportunistic pathogens; G. morbillorum and, less frequently, G. haemolysans are detected in endocarditis and other opportunistic infections (García López and Martín-Galiano 2020).
