Actinomyces naeslundii strain W8-2-3

Actinomyces naeslundii strain W8-2-3 is a Gram-positive bacterium primarily found in the submucosal sulcus of the human oral cavity. This organism is classified as a facultative anaerobe, indicating that it can grow in both the presence and absence of oxygen. A. naeslundii has a single replicon, which is characteristic of its genetic structure. This strain has been associated with significant health effects, notably dental caries and actinomycosis. Dental caries, or tooth decay, is a common consequence of the metabolic activities of A. naeslundii, which can contribute to the demineralization of dental tissues. Actinomycosis, on the other hand, is an infection caused by Actinomyces species, which can lead to various clinical manifestations, particularly in tissues of the head and neck. Considering its habitat and associations with oral health conditions, A. naeslundii strain W8-2-3 plays a crucial role in the microbial ecosystems of the human mouth. Its presence highlights the complex interactions between oral bacteria and human health, emphasizing the need for maintaining a balanced oral microbiome to prevent diseases such as dental caries and actinomycosis. Understanding the specific traits and behaviors of this strain can provide insights into its role in oral health and disease. The strain is cataloged under accession MSKY00000000.1, which facilitates further research and investigation into its characteristics and impacts.
