Collinsella aerofaciens


A healthy result should fall into the range 14 - 1900 CFU/g stool.

Collinsella aerofaciens is a group of bacteria found in the gut and also on the surface of the tongue. It is named after the microbiologist Matthew Collins.

The species name aerofaciens comes from the Greek words “aeros” (gas) and “faciens”, (producing).

The species of the Collinsella genus are known for their ability to ferment a wide range of carbohydrates, including starch, forming products such as hydrogen gas and ethanol.

A reduced abundance of this group of bacteria has been related with more severe symptoms in patients suffering from irritable bowel syndrome.
