abstract = {The use of laboratory mice with a natural microbiome, such
as 'Wildling mice', offers a promising research tool for
both basic and applied science due to their close
resemblance to the human superorganism. However, the
breeding and maintenance of these mice, which harbor a
diverse microbiome including bacteria, viruses, and
parasites, pose significant challenges for animal husbandry
facilities at research institutions. To address these
challenges, a specialized facility concept was developed for
housing 'Wildling mice' at Charité - Universitätsmedizin
Berlin. This approach involved designing a facility with
specific structural features and operational protocols to
effectively contain the natural microbiome, thereby
protecting areas with higher hygiene standards. A
methodology for blood sampling from both specified
pathogen-free (SPF) and 'Wildling mice' for
immunophenotyping is demonstrated, highlighting the workflow
and biocontainment measures implemented in the facility.
Remarkable results reveal that 'Wildling mice' exposed to a
natural microbiome develop distinct immune cell populations,
which are significantly reduced in mice bred and maintained
under stringent hygiene conditions. The significance of this
study lies in its potential to provide researchers with
access to mice that possess a natural microbiome and a
mature immune system similar to that of human adults. This
approach could enhance the translatability of preclinical
findings into clinical practice, thereby advancing the field
of biomedical research.},
