Method description

ProDigest's short-term colonic simulation is an in vitro model for rapid screening of the interaction between test products and the gut microbiome. The key microbial saccharolytic and proteolytic markers are analysed as well as evolution in the composition of the microbiome and other endpoints as desired by the customer. Ideally suited for cost-efficient investigation of many test products, combinations or formulations, inter-individual variability in effect, ... Model organisms:

  • - human: adult vs infant, healthy vs diseased
  • - dog
  • - cat
  • - pig
  • - poultry (caecum)
Method status
  • History of use
  • Internally validated
  • Published in peer reviewed journal

Pros, cons & Future potential

Advantages
  • Representative of donor microbiome ;
  • Robust simulation ;
  • Enough sampling for multiple analyses and kinetic investigations.
Challenges

This set-up considers short-term interactions between one dose of test product and the microbiome.
