Fig. 4: WU23 and MNV1 infect intestinal and extraintestinal tissues of neonatal B6 mice.

Groups of P3 C57BL/6J (B6) pups (n = 5 per condition) were infected by i.g. with 107 TCID50 units of MNV1, WU23, CR6 or mock inoculum. Virus titers were determined by plaque assay for the duodenum (a), ileum (b), colon (c), spleen (d) and liver (e) at the indicated timepoints. Mice from a minimum of two different litters per condition were analyzed. Data are presented as mean ± s.e.m.; dashed line indicates limit of detection.
