Characterization of a Signaling System in Streptococcus mitis That Mediates Interspecies Communication with Streptococcus pneumoniae

Applied and Environmental Microbiology, 2018
Bacteria secrete signal molecules into the environment which are sensed by other cells when the density reaches a certain threshold. In this study, we describe a communication system in Streptococcus mitis, a commensal species from the oral cavity, which

The Effect of Non‐Surgical Periodontal Therapy on Subgingival Microbiota: A Systematic Review and Meta‐Analysis

Journal of Periodontal Research, EarlyView.
This paper provides crucial insights and evidence on the effect of non‐surgical periodontal therapy on subgingival microbiota. NSPT leads to significant reductions in disease‐associated microbial species. Supportive periodontal care provision provided further decrease in mean counts of disease‐associated species.

Oral Delivery of a Novel Recombinant Streptococcus mitis Vector Elicits Robust Vaccine Antigen-Specific Oral Mucosal and Systemic Antibody Responses and T Cell Tolerance. [PDF]

PLoS ONE, 2015
The pioneer human oral commensal bacterium Streptococcus mitis has unique biologic features that make it an attractive mucosal vaccine or therapeutic delivery vector. S. mitis is safe as a natural persistent colonizer of the mouth, throat and nasopharynx

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

The oral commensal Streptococcus mitis activates the aryl hydrocarbon receptor in human oral epithelial cells

International Journal of Oral Science, 2017
Streptococcus mitis (S. mitis) is a pioneer commensal bacterial species colonizing many of the surfaces of the oral cavity in healthy individuals. Yet, not much information is available regarding its interaction with the host.

Streptococcus tigurinus, a Novel Member of the Streptococcus mitis Group, Causes Invasive Infections [PDF]

Journal of Clinical Microbiology, 2012
ABSTRACTWe recently described the novel speciesStreptococcus tigurinussp. nov. belonging to theStreptococcus mitisgroup. The type strain AZ_3aTofS. tigurinuswas originally isolated from a patient with infective endocarditis. According to its phenotypic and molecular characteristics,S. tigurinusis most closely related toStreptococcus mitis,Streptococcus
