Gemella is a genus of Gram-positive, facultatively anaerobic cocci that are normal commensals of the oral cavity. Species include G. morbillorum, G. haemolysans, and G. sanguinis.
In the WikiBiome context, Gemella is notable for its oral-gut translocation pattern—an oral commensal that appears in gut and tumor microbiome studies, suggesting translocation as a marker of barrier disruption.

Enriched in colorectal cancer tumor microbiome, consistent with oral bacteria translocating to the colon—a pattern shared with fusobacterium nucleatum and peptostreptococcus stomatis.
Part of the oral microbiota altered in H. pylori-associated reflux esophagitis.
ASD: Depleted in gut microbiota of young ASD children.
Endometriosis: Part of vaginal/cervical microbiome shifts.
Genital tract: Abundance modulated by mucosal lactoferrin levels.
