Streptococcus oralis subsp. tigurinus strain RH_48720_11

Streptococcus oralis subsp. tigurinus strain RH_48720_11 is a Gram-positive cocci bacterium that typically exists in pairs or chains. This strain is classified as a facultative anaerobe, which means it can grow in both the presence and absence of oxygen. It is mesophilic, thriving within a moderate temperature range conducive to human hosts, specifically Homo sapiens. Strain RH_48720_11 is non-motile and does not possess flagella, indicating that it does not have the means for active movement. It is characterized by having a single replicon, suggesting a simpler genetic architecture compared to other more complex organisms. This strain is known to be free-living, indicating that while it is associated with human hosts, it can exist independently in its environment. Clinically, S. oralis subsp. tigurinus strain RH_48720_11 has been linked to several serious health conditions, including endocarditis, peritonitis, meningitis, and invasive disease. Its pathogenicity is specifically noted in human infections, emphasizing its potential to cause severe health issues such as infective endocarditis. Understanding the traits of this strain highlights its role in human health and disease. The presence of S. oralis subsp. tigurinus in the human microbiome underscores the delicate balance between commensal relationships and pathogenic potential, illustrating how certain strains can shift from benign to harmful under specific conditions.
