Insights

This study details a cost-effective fecal microbiota transplantation (FMT) protocol for mice in specific pathogen-free (SPF) facilities. The method uses microaerophilic processing and oral gavage for efficient bacterial community engraftment.

Area of Science:

  • Microbiology
  • Gnotobiology
  • Animal models

Background:

  • Fecal microbiota transplantation (FMT) shows promise in pre-clinical research.
  • Standard FMT protocols often require specialized, expensive equipment like anoxic cabinets.
  • There is a need for accessible and cost-effective FMT methods in research settings.

Purpose of the Study:

  • To present a detailed protocol for performing FMT in mice within a specific pathogen-free (SPF) facility.
  • To describe a mobile and cost-effective alternative to anoxic cabinets for FMT sample processing.
  • To outline procedures for successful bacterial community engraftment.

Main Methods:

  • Fecal sample collection from age- and gender-matched healthy donor mice.
  • Microaerophilic processing of freshly collected fecal pellets.
  • Administration of fecal samples via oral gavage to recipient mice.

Main Results:

  • Successful engraftment of bacterial communities was achieved using the described protocol.
  • The protocol provides a viable, cost-effective alternative to traditional anoxic methods.
  • The method is suitable for mice housed in SPF facilities.

Conclusions:

  • This protocol offers a practical and economical approach to FMT in pre-clinical mouse models.
  • The described method facilitates reproducible bacterial community transplantation in SPF environments.
  • The protocol can be implemented using readily available, mobile equipment.
