Streptococcus oralis subsp. tigurinus strain UC5873

Streptococcus oralis subsp. tigurinus strain UC5873 is a Gram-positive, cocci-shaped bacterium that typically exists in pairs or chains. This strain is classified as a facultative anaerobe, meaning it can thrive in both the presence and absence of oxygen. Notably, it has a mesophilic temperature range, which is conducive to growth at moderate temperatures. The strain is characterized by the absence of mobility, as it does not possess flagella. S. oralis subsp. tigurinus strain UC5873 is primarily associated with human hosts and is recognized for its potential pathogenicity. It has been implicated in serious health conditions, including endocarditis, peritonitis, meningitis, and invasive disease. These associations highlight the strain's role in human health, particularly in immunocompromised individuals. The strain is classified as free-living, suggesting that it can exist independently within its host's environment. It contains a single replicon, indicating a streamlined genomic structure that may contribute to its adaptability within host-associated habitats. Understanding the ecological and biological characteristics of S. oralis subsp. tigurinus strain UC5873 is crucial, especially given its implications for human health. The presence of this strain in the human microbiome underscores the importance of monitoring such bacteria, as they can transition from commensal organisms to pathogens under certain conditions, leading to invasive diseases.
