Persists: Mutaflor

Mutaflor is also known a Escherichia Coli Nissle 1917. 1917 being the year of discovery. It has been in production for over a century.

EcN 1917 (O6:K5:H1) was isolated by Prof. Alfred Nissle from Freiburg, Germany, in 1917 from the intestinal microflora of a young soldier. This soldier – unlike his comrades – did not develop infectious diarrhea, when stationed during World War I in Southeastern Europe (Dobrudja/Balkan peninsula), endemic for Shigella at that time. The strain was named E. coli strain Nissle 1917.

Using this E. coli strain Prof. Nissle developed the probiotic drug Mutaflor® and introduced it into medical practice in the same year. Since 1917, Mutaflor® is available in the German pharmaceutical market without interruption and recently also in Italy as EcN (cadigroup).

It gets a full FOUR+ thumbs up:

  • Strain is named
  • Human sourced – Country of origin is Germany
  • Have been shown to persist in at least 10% of patients
  • Extremely well studied. I have listed a few articles from the US National Library of Medicine below…
