| Description | Streptococcus parasanguinis ATCC 15912 is a mesophilic, facultative anaerobic, gram-positive coccus that thrives in temperatures ranging from 20°C to 40°C. As a facultative anaerobe, it can grow in the presence or absence of oxygen, although it prefers aerobic conditions. Its metabolism is heterotrophic, meaning it obtains energy by breaking down organic compounds. Specifically, it uses fermentation to produce energy, utilizing the substrate glucose and other carbohydrates. Streptococcus parasanguinis ATCC 15912 is spherical in shape, typically ranging from 0.5 to 1.0 μm in diameter, and forms chains or pairs. Its Gram-staining properties are characteristic of gram-positive bacteria, where the cell wall is composed of a thick layer of peptidoglycan. As an inhabitant of the oral cavity, this microbe is found on the surface of teeth and along the gingiva. It is also detected in the saliva, tongue, and palatal mucosa. In addition, it has been isolated from blood and other body fluids, particularly in cases of bacteremia. Streptococcus parasanguinis ATCC 15912 is a common commensal microbe, co-existing with other oral bacteria and playing a role in the development of dental plaque. Despite its non-pathogenic nature, it has been implicated in diseases such as periodontitis and endocarditis. Moreover, it has been shown to be potentially involved in the early stages of cardiovascular disease. This microbe's ability to form biofilms, adhere to surfaces, and produce extracellular enzymes contributes to its pathogenic potential. In summary, Streptococcus parasanguinis ATCC 15912 is a versatile, opportunistic microbe that thrives in various environments, from the oral cavity to blood and other body fluids. Its complex interactions with other microorganisms and host tissues make it an important focus of research in the fields of oral and cardiovascular health. |
