Citrobacter rodentium Relies on Commensals for Colonization of the Colonic Mucosa
Summary: We investigated the role of commensals at the peak of infection with the colonic mouse pathogen Citrobacter rodentium.Bioluminescent and kanamycin (Kan)-resistant C.rodentium persisted avirulently in the cecal lumen of mice continuously treated with Kan.A single Kan treatment was sufficient to displace C.rodentium from the colonic mucosa,
