Fig. 4: Duration of MuAstV shedding in feces, detected by RT-PCR, after first and second infection over 13 weeks (long-term experiment).
From: Murine astrovirus infection course and antibody response in different mouse strains

a, The percentage of virus-positive mice among 12 mice per mouse strain (y axis) is plotted against wpi over 13 weeks (x axis). CD1 in blue, C57BL/6J in red, BALB/c in green and NSG in purple. Arrows indicate the first infection at 0 wpi and second infection at 9 wpi (n = 12). b, The onset and duration of virus shedding is shown for each individual animal.
