Streptococcus gordonii strain KCOM 1506 (= ChDC B679)

Streptococcus gordonii strain KCOM 1506, also known as ChDC B679, is a Gram-positive cocci bacterium predominantly found in association with its host, Homo sapiens. This strain exhibits a characteristic arrangement of cells in chains and pairs, reflecting its typical growth pattern within the oral cavity and other human-associated environments. As a facultative anaerobe, S. gordonii can thrive in both aerobic and anaerobic conditions, which is advantageous for survival in the variable oxygen levels encountered in the human mouth. The optimal growth temperature for this strain is 37°C, placing it within the mesophilic range, which is typical for many human-associated microorganisms. S. gordonii strain KCOM 1506 lacks mobility, as it does not possess flagella, and it features a single membrane with one replicon. This bacterium is considered free-living, indicating its ability to reside independently within its ecological niche, while also being part of the complex microbial community found in humans. The presence of S. gordonii in the human microbiome is significant, as it plays a role in oral health and may influence the development of dental biofilms. Understanding the traits of this strain contributes to our knowledge of its ecological interactions within the human host and its potential implications for health and disease. The accession number for this strain is NZ_CP012648.1, which provides a reference for further genomic studies.
