Oral-Gut Translocation

This marker evaluates the presence of typical oral bacteria in your large intestine. Under normal conditions, stomach acid destroys these microorganisms before they reach the colon. High oral translocation indicates that the stomach acid barrier has failed (hypochlorhydria) or that your intestinal ecosystem is so weakened that it allows these oral bacteria to settle. It is a key indicator of inflammation and poor upper digestive function.

Every day, when you swallow or eat, you ingest billions of bacteria from your dental plaque, tongue, and gums.

To protect your gut from this constant invasion, human gastric juice has an extremely acidic pH (between 1.5 and 3.0), designed to sterilize food and destroy almost all oral bacteria.

However, when this defense mechanism fails, whether due to chronic stress, aging, or the daily use of gastric protectors like Omeprazole, oral bacteria survive the passage through the stomach, cross the small intestine, and reach the colon. This phenomenon is known as the "oralization" of the gut microbiome. Once there, as it is not their natural habitat, they aggressively compete for nutrients and often trigger inflammatory responses in the intestinal lining.

The invasion of the intestine by oral bacteria is not a harmless event; it is linked to chronic pathologies:

• Inflammatory Bowel Disease (IBD): Oral bacteria such as Klebsiella and certain strains of Streptococcus have a proven ability to activate immune cells (Th1 cells) in the intestine, causing severe flare-ups in patients with Crohn's Disease or Ulcerative Colitis.
• Colorectal Cancer: One of the most impactful discoveries in recent oncology is that Fusobacterium nucleatum (a bacterium responsible for periodontitis or bleeding gums) is capable of translocating to the colon, adhering to benign polyps, and accelerating their mutation into cancerous tumors.
• False Food "Sensitivity": The lack of stomach acid that allows this translocation also prevents proper protein digestion. Food reaches the intestine partially digested, where these oral bacteria ferment it chaotically, causing gas, heaviness, and symptoms similar to intolerances.

Oral-intestinal translocation detection is a sophisticated analysis that leverages shotgun metagenomic sequencing to quantify the relative abundance of a panel of strictly oral taxa that rarely colonize the healthy colon. We specifically look for enrichment of genera such as Fusobacterium, Porphyromonas, Haemophilus, Veillonella, and specific species such as Streptococcus salivarius and Streptococcus mutans.

A low or zero percentage indicates optimal superior digestive physiology. The gastric barrier functions correctly. Higher values suggest hypochlorhydria (low stomach acidity) or profound dysbiosis. The strategy in case of high detection does not usually focus on the colon, but "upstream." It involves thoroughly reviewing dental hygiene (treating gingivitis), evaluating the possible gradual withdrawal of PPI (Proton Pump Inhibitor) drugs under medical supervision, supporting gastric acidity (use of betaine HCl, apple cider vinegar, or mindful chewing), and boosting native colonic bacteria to displace invaders.
