Streptococcus oralis strain DD25

Streptococcus oralis strain DD25 is a Gram-positive, cocci-shaped bacterium characterized by its arrangement in pairs and chains. It is classified as a facultative anaerobe, indicating its ability to thrive in both aerobic and anaerobic environments. This strain is non-motile and does not possess flagella, which is typical for many streptococci. The habitat of S. oralis DD25 is primarily host-associated, with Homo sapiens identified as its main host. This bacterium is recognized for its pathogenic potential, being associated with several serious health conditions, including endocarditis, peritonitis, meningitis, infective endocarditis, and other invasive diseases. Its pathogenicity is particularly significant in human hosts, highlighting its role in opportunistic infections. S. oralis DD25 is mesophilic, thriving in moderate temperature ranges, and contains a single replicon, which is common among bacterial species. The strain's presence in the human microbiome suggests a complex biotic relationship, as it can be both free-living and pathogenic depending on the context. The ecological insight from this data indicates that while S. oralis can be a part of the normal microbiota, its ability to cause serious infections underscores the importance of maintaining a balanced microbial ecosystem in humans. Disruptions in this balance may lead to the opportunistic emergence of pathogens like S. oralis DD25, which can result in significant health challenges. Accessions for this strain are recorded under NZ_CM003838.1, providing a resource for further research and characterization.
