Fig. 1. MNV infection causes disease in a virus strain-dependent manner.

Fig. 1

a, b Groups of C57BL/6J (n = 6 for mock, n = 8 for MNV-1, n = 6 for MNV-3, n = 8 for MNV-CR6) or C57BL/6J-Ifnar−/− (n = 6 for mock, n = 8 for MNV-1, n = 7 for MNV-3, n = 7 for MNV-CR6) mice were perorally infected with 107 TCID50 units of MNV-1 (blue), MNV-3 (red), MNV-CR6 (green), or mock (black) inoculum and followed for weight loss (a) and survival (b). c Representative images of fecal samples indicating each score used to assess for diarrhea are shown. d, e Groups of 3-day-old BALB/c pups were infected with 108 TCID50 units of MNV-1 (blue), UV-inactivated MNV-1 (white with blue border), MNV-3 (red), MNV-CR6 (green), or mock (black) inoculum by oral gavage. Pups (n = 19 for mock, n = 21 for MNV-1, n = 9 for UV-inactivated MNV-1, n = 21 for MNV-3, n = 19 for MNV-CR6) were monitored for fecal consistency by palpating their abdomens (d). The proportion of mice scoring a 3 or 4 at any time point over the 5 days course of infection is presented as the incidence of diarrhea (e). Error bars denote standard errors of mean in all figures. P values were determined using two-way ANOVA with corrections for multiple comparisons. Source data are provided as a Source data file.
