Introducing: Oral Species Biomarker

Uncover the oral-gut connection for better care

Assessing oral species in the gut can reveal important insights about health including intestinal inflammation.

We’ve added the Oral Species biomarker to all Microba test reports to support faster, more confident assessment of oral-origin microbes in the gut.

This biomarker reports on over 410 oral species in the gut, empowering practitioners to assess the oral-gut connection and associations with intestinal inflammation, PPI use and bacterial load.

What the Oral Species biomarker delivers

Uncover the oral-gut connection: Reveal how microbes from the mouth can appear in the gut, identifying a hidden contributor of intestinal inflammation.

Investigate oral species with confidence: Detect and interpret over 410 oral species using Microba’s new Oral Species biomarker, powered by the oral species index.

Deliver better care: Use the Oral Species biomarker for better insights and more targeted, evidence-based care.

How the Oral Species biomarker enables better care

Detect oral species in the gut
Identify and quantify over 410 oral-origin species using Microba’s metagenomic sequencing and the Human Oral Microbiome Database (HOMD v2).

Assess intestinal inflammation
The Oral Species biomarker sits within the Intestinal Inflammation category, helping practitioners interpret microbial patterns linked to inflammatory activity.

Measure with precision
Powered by the Oral Species Index (OSI), a validated biomarker that reflects both the presence and abundance of oral-origin microbes in the gut.

Interpret results easily
Results are classified as not detected, optimal, borderline high, or high for clear, actionable reporting.

Apply evidence-based insights
Draw on clinical evidence linking high oral species with inflammation, PPI use, bacterial load, and oral health.

Integrate into patient care
Access the marker directly in Microba test reports and PDFs — visible to both practitioners and patients for shared understanding.

Unlock deeper insights with Microbiome Explorer and GI Navigator

Oral Species is now available in all new Microba test reports.

This new biomarker brings once hidden insights into clear view for practitioners and patients, supporting better science, better insights and better care.
