Barbara Rehermann and Stephan Rosshart first collected 800 wild house mice (Mus musculus domesticus) in the Washington, D.C., metro area, and compared their DNA and gut bacteria both with a lab mouse strain and with wild mice from all over the world. (sciencemag.org)
This breeding led to the creation of progenitors of modern laboratory mice as hybrids among M. m. domesticus, M. m. musculus and other subspecies. (genome.gov)
