- aThree 10-12 week ♀ mice of each strain were infected with HSV-1 strain 2 via the oral mucosa. 'Focal' areas of viral antigen positive cells were determined in serial sections of the brainstem-cerebellum (BST-CB) by IHC and CFV counterstain.
- bSections of the BST were examined on the first day that 'focal' areas appear for each mouse strain.
- cSections of the CB were examined on the first day that 'focal' areas appear for each mouse strain.
- dAverage number of 'focal' areas of viral antigen ± SD per section. Differences among mouse strains are all statistically significant at P < 0.001 except for the difference between SJL/J and A/J BST which was NS.
- eAs a single 'focal' area could be represented in several sections, the greatest diameter for each'focal' area was determined. The average diameter ± SD of the 'focal' areas for the three mouse strains was then calculated. Differences between the three mouse strains are all statistically significant at P < 0.001.
