Streptococcus oralis subsp. tigurinus str. 859

Streptococcus oralis subsp. tigurinus str. 859 is a Gram-positive, cocci-shaped bacterium that typically forms pairs or chains. It is classified as a facultative anaerobe, allowing it to survive in both aerobic and anaerobic environments. This organism is mesophilic, thriving within moderate temperature ranges suitable for human hosts. S. oralis subsp. tigurinus is primarily associated with humans (Homo sapiens), indicating a close biotic relationship. Despite its association with a host, it exhibits characteristics of free-living organisms, which suggests it can exist independently in the environment. Notably, this strain does not possess mobility, as it lacks flagella. The bacterium has one replicon, indicating a single circular chromosome, which is typical for many species within the Streptococcus genus. The accession number for this strain is LNVH00000000.1, which is relevant for genomic and taxonomic studies. An ecological insight into S. oralis subsp. tigurinus str. 859 is its potential role in the human microbiome. As a member of the oral microbiota, it may contribute to oral health and disease dynamics, influencing factors such as dental plaque formation and the overall balance of microbial communities in the oral cavity. Its facultative anaerobic nature allows it to adapt to varying oxygen levels, making it well-suited to the diverse conditions found within the human mouth.
