    Abstract

    The microbiome of mice and rats have largely been ignored for general basic research until recently. In the past few years, specific microbiome studies have demonstrated that research results using animal models may have been influenced by an unchecked and unmonitored microbial consortia, and is impacted by virtually all investigated husbandry and housing variables. At the phylum level, barrier rooms which house standard strains in open-top cages may appear to be similar among a single vendor’s barrier rooms within strain, sex, and age. The reality is that at the genus and species level, there are usually differences in the diversity and abundance of bacteria that may provide research outcomes that are room, and possibly time specific. As researchers are starting to take note of which room they receive standard mouse strains from and question, “what is the consortium within the rooms,” vendors may consider providing routine monitoring of the microbial flora as part of the model characterisation. Can vendors be expected to maintain a near static microbiome status in the barrier rooms or other housing units? What can vendors and basic lab animal researchers learn from microbiome researchers who have brought forward the awareness of microbial drift? This workshop will focus on the challenges of maintaining a static microbiome among different housing schemes used for basic research and the methods and monitoring procedures that can be implemented to mitigate microbial drift from rodent model production through research investigations.
