Mice The mice used in this study were housed in pathogen-free facilities at the University of Chicago and Stanford University. All mice were housed in positively pressurized, individually ventilated cage racks and changed in biological safety cabinets. Cage supplies were sanitized using hot water (82 °C). Bedding and shredded-paper enrichment were autoclaved and cages were provided with irradiated food. Reverse Osmosis …
