Oral Dysbiotic Communities and Their Implications in Systemic Diseases

Area of Science:

• Microbiology
• Human Health
• Oral Health

Background:

• The human body hosts diverse microbial communities, collectively known as the human microbiome.
• The oral microbiome comprises symbiotic and pathogenic bacteria, with imbalances (dysbiosis) linked to disease.
• Dysbiosis is driven by keystone pathogens and involves shifts in microbial community composition and abundance.

Purpose of the Study:

• To review the mechanisms of dysbiosis in the human microbiome.
• To explore the role of keystone pathogens in oral dysbiosis and systemic implications.
• To highlight the interactions within dysbiotic communities and their virulence factors.

Main Methods:

• Literature review of studies on human microbiome, dysbiosis, and keystone pathogens.
• Analysis of the relationship between oral dysbiosis and systemic diseases.
• Examination of bacterial interactions and virulence factors contributing to disease.

Main Results:

• Dysbiosis, often initiated by keystone pathogens, disrupts microbial community balance.
• Oral dysbiosis, particularly periodontitis, is associated with systemic conditions like cardiovascular disease, diabetes, and Alzheimer's disease.
• Bacterial interactions and novel virulence factors play crucial roles in dysbiosis and disease progression.

Conclusions:

• Understanding dysbiosis and keystone pathogens is critical for managing microbiome-related diseases.
• Further research into bacterial interactions and virulence factors can reveal new therapeutic targets.
• Maintaining microbial balance is essential for overall host health and preventing systemic complications.
