Mutaflor Safety Profile

“Mutaflor has shown a perfect safety record for almost a century”  – ECCO Consensus on UC: Current management

Mutaflor meets all of today’s safety requirements. The non-pathogenicity of the Mutaflor strain has been proven to the genetical level by using methods of molecular biology. The Escherichia coli strain Nissle 1917 – designated DSM 6601 in the German Collection for Microorganisms in Braunschweig – is one of the best-examined therapeutically relevant bacterial strains worldwide.

Mutaflor (E. coli strain Nissle 1917) has no pathogenic characteristics:

  • No production of enterotoxins (Shiga toxins, heat-stable and heat-labile toxins)
  • No production of cytotoxins (CNF)
  • No enteroinvasiveness
  • No pathogenic adhesion factors (e.g. no CFA I/II, P, M and S fimbriae)
  • No hemolysins
  • No serum resistance
  • No uropathogenicity
  • No antibiotic-resistance genes
