Figure 1From: Respiratory infection of mice with mammalian reoviruses causes systemic infection with age and strain dependent pneumonia and encephalitisAge and virus dependent fatal dose response of reovirus T1L and T3D infection in adult and suckling Balb-c mice. The number of animals monitored in each group is shown as values of n. Top panel. Adult mice were intranasaly infected with 107 pfu of either T1L or T3D and monitored for 30Â days. Lower dosages did not induce fatality (not shown). Bottom panel. Suckling mice at 2Â days of age were intranasaly infected with graded dosages of either T1L or T3D and monitored for 30Â days. The times to death were significantly different using the students t test for the comparisons indicated in brackets.Back to article page
