Norovirus triggered microbiota-driven mucosal inflammation in interleukin 10-deficient mice.

Background: Infection may trigger clinically overt mucosal inflammation in patients with predisposition for inflammatory bowel disease. However, the impact of particular enteropathogenic microorganisms is ill-defined. In this study, the influence of murine norovirus (MNV) infection on clinical, histopathological, and immunological features of mucosal inflammation in the IL10-deficient (Il10) mouse model of inflammatory bowel disease was examined.
