Streptococcus oralis subsp. oralis strain OD_321121_09

Streptococcus oralis subsp. oralis strain OD_321121_09 is a Gram-positive, cocci-shaped bacterium that typically arranges itself in pairs and chains. This strain is a facultative anaerobe, indicating its ability to thrive in both aerobic and anaerobic environments, and it is classified as mesophilic, as it prefers moderate temperature ranges for optimal growth. S. oralis subsp. oralis is associated with Homo sapiens as its primary host and exhibits a free-living biotic relationship. It is notable for its pathogenic potential, being implicated in various serious health conditions, including endocarditis, peritonitis, meningitis, and invasive diseases such as infective endocarditis. These health effects underscore its importance in clinical microbiology, particularly concerning human health. The strain does not possess mobility, as it lacks flagella, which is consistent with its cell arrangement and lifestyle. Furthermore, it has a single replicon, reflecting its genomic organization. Given its association with serious infections in humans, S. oralis subsp. oralis strain OD_321121_09 highlights the significance of oral microbiota in health and disease. The presence of this bacterium in the human body suggests a dual role where it can be part of the normal flora but also poses risks for opportunistic infections, particularly in immunocompromised individuals. Thus, understanding this strain's characteristics can contribute to better strategies for managing infections associated with oral bacteria.
