Gut Bacteria Could Eradicate Food Allergies

Print Friendly, PDF & Email

Bacteria from a family that includes potentially deadly infectious bugs may protect against food allergies, research has shown.

Clostridia encompasses around 100 bacterial species, some of which live harmlessly in the gut.

Others are responsible for gangrene, tetanus, botulism food poisoning and hospital infections caused by Clostridium difficile.

Gut bacteria hold the key to beating food allergies, researchers say

HOW IT WORKS

How It Works

Environmental effects on gut flora – including over-use of antibiotics, high fat diets, excessive hygiene and even infant formula feeding – may be contributing to food allergies by suppressing Clostridia, the researchers believe.  

Tests indicated that Clostridia caused immune cells to produce high levels of a signalling molecule known to decrease permeability of the intestinal lining.

This in turn reduced the chances of allergens – molecules that trigger an allergic reaction – leaking into the bloodstream.

The team is now working on turning the discovery into a probiotic food allergy treatment, and has filed a provisional patent. 

The new study suggests that ‘friendly’ Clostridia have a unique ability to block the harmful immune response behind food allergies.

Tests on ‘sterile’ mice sensitized to peanuts showed that introducing a Clostridia cocktail into their bacteria-free guts reversed their allergy.

Re-introduction of another major group of gut bacteria, Bacteroides, did not have the same effect.

Tests indicated that Clostridia caused immune cells to produce high levels of a signalling molecule known to decrease permeability of the intestinal lining.

This in turn reduced the chances of allergens – molecules that trigger an allergic reaction – leaking into the bloodstream.

US lead scientist Professor Cathryn Nagler, from the University of Chicago, said: ‘We’ve identified a bacterial population that protects against food allergen sensitization.
