Periodontitis and Inflammatory Bowel Diseases: Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
This review aims to provide a conceptual framework for understanding the mechanistic interplay between periodontitis and IBD, with a particular emphasis on the microbial and immunological crosstalk linking the oral cavity and the gastrointestinal tract.

Image_1_Effects of Expression of Streptococcus pneumoniae PspC on the Ability of Streptococcus mitis to Evade Complement-Mediated Immunity.JPEG

, 2021
Streptococcus pneumoniae and Streptococcus mitis are genetically closely related and both frequently colonise the naso-oropharynx, yet S. pneumoniae is a common cause of invasive infections whereas S. mitis is only weakly pathogenic.

Oral Health, Periodontitis, and Respiratory Diseases: Biological Pathways

Journal of Periodontal Research, EarlyView.
This narrative review aims to provide a comprehensive update on the potential mechanisms by which poor oral health and periodontitis impact lung health, focusing on pneumonia, COPD, and asthma. ABSTRACT Poor oral hygiene and periodontitis influence lung diseases such as pneumonia, chronic obstructive pulmonary disease (COPD), COVID‐19, and asthma.

Periodontal Salutogenesis: Why Are Some People Resistant to Oral Microbial Dysbiosis and Destructive Inflammation?

Journal of Periodontal Research, EarlyView.
Emerging evidence suggests that periodontal health is not simply the absence of disease, but the result of a dynamic interaction between biological resilience, healthy lifestyles, adaptive coping mechanisms, and supportive environments. This results in a strong sense of coherence, which is not only a psychological state but also a biological state ...

table_2_Antibodies Reactive to Commensal Streptococcus mitis Show Cross-Reactivity With Virulent Streptococcus pneumoniae Serotypes.docx

, 2018
Current vaccines against Streptococcus pneumoniae, a bacterial species that afflicts people by causing a wide spectrum of diseases, do not protect against all pneumococcal serotypes. Thus, alternative vaccines to fight pneumococcal infections that target

The ComEA/ComEC Operon is Critical for Nitrosative Stress Tolerance by an Oral Commensal

Molecular Oral Microbiology, EarlyView.
ABSTRACT Oral commensal streptococci play a large role in mediating microbial homeostasis. Our prior work has demonstrated that hydrogen peroxide (H2O2) produced by oral commensal streptococci can react with salivary nitrite (NO2) and generate peroxynitrite (ONOO−), a potent antimicrobial.

Regulation of Synthesis of  -Fructofuranosidase (Invertase) in Streptococcus mitis

Microbiology, 1980
beta-Fructofuranosidase activity was found to be cell-bound in Streptococcus mitis ATCC 903. The following evidence suggests that induction functions as a regulatory mechanism for beta-fructofuranosidase in S. mitis: (1) on transfer of glucose-grown exponential phase bacteria to sucrose medium, the specific activity of beta-fructofuranosidase increased

Postoperative Antibiotic Duration and Treatment Failure After Aseptic Revision Arthroplasty With a Single Unexpected Positive Culture: A Retrospective Cohort Study

Orthopaedic Surgery, EarlyView.
Prolonged postoperative antibiotic use was associated with higher treatment failure in aseptic revision arthroplasty with a single unexpected positive culture, suggesting that extended antibiotic therapy may not improve outcomes and highlighting the need for individualized treatment strategies.

Streptococcus mitis Strains Causing Severe Clinical Disease in Cancer Patients

Emerging Infectious Diseases, 2014
The genetically diverse viridans group streptococci (VGS) are increasingly recognized as the cause of a variety of human diseases. We used a recently developed multilocus sequence analysis scheme to define the species of 118 unique VGS strains causing ...
