Streptococcus oralis subsp. oralis strain COL85/1862

Streptococcus oralis subsp. oralis strain COL85/1862 is a Gram-positive bacterium characterized by its cocci shape and tendency to arrange in pairs or chains. This organism is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. The strain is mesophilic, indicating that it grows optimally at moderate temperatures, typical of human body conditions. S. oralis subsp. oralis is a free-living bacterium that is associated with Homo sapiens, where it can inhabit various niches within the host. It has been implicated in several serious health conditions, including endocarditis, peritonitis, meningitis, and invasive diseases such as infective endocarditis. Its pathogenicity highlights its potential to cause significant clinical outcomes in humans, particularly among individuals with compromised immune systems or pre-existing health issues. With a single replicon, this strain does not possess flagella, which correlates with its non-motile nature. The absence of mobility suggests that its pathogenic mechanisms may rely on adherence to host tissues rather than active movement. Understanding the traits of S. oralis subsp. oralis strain COL85/1862 contributes to the broader knowledge of oral microbiota and its potential to cause systemic infections. This insight underscores the importance of maintaining oral health to prevent the translocation of such bacteria into the bloodstream, where they can lead to serious infections.
