Gut Microbiota Parameters Potentially Useful in Clinical Perspective.

Area of Science:

• Microbiome Research
• Clinical Diagnostics
• Nutritional Science

Background:

• Growing interest in gut microbiota's role in various diseases.
• Potential link between gut bacteria and conditions like obesity, metabolic syndrome, and colon neoplasms.
• Need for affordable and reliable gut microbiota biomarkers for clinical application.

Purpose of the Study:

• To review potential gut microbiota biomarkers.
• To explore the diagnostic utility of specific microbial ratios.
• To highlight the future role of these biomarkers in routine clinical practice.

Main Methods:

• Narrative review of existing literature on gut microbiota ratios.
• Focus on specific microbial ratios: Firmicutes/Bacteroidetes, Gram-positive/Gram-negative, Prevotella/Bacteroides, and Fusobacterium nucleatum/Faecalibacterium prausnitzii.
• Analysis of their potential as diagnostic markers.

Main Results:

• Several microbial ratios show potential as biomarkers for various health conditions.
• The Firmicutes/Bacteroidetes ratio is frequently discussed in relation to obesity and metabolic health.
• Other ratios like Prevotella/Bacteroides and F. nucleatum/F. prausnitzii may indicate specific disease states.

Conclusions:

• Gut microbiota analysis holds promise for diagnosing a range of diseases.
• Specific microbial ratios could serve as valuable, affordable biomarkers.
• Further research is needed to validate these markers for routine clinical diagnostics.
