CD8A and infection: Microscopic screening of lung sections for individual mice from the largest infection group revealed three times higher number of CD8+CD103+ T cell patches on average in those recovering from infection (#F3, 9 patches per 1/section and #F4, 10 patches/section) than in those which did not fully recover their initial body mass (#-F5-F10, 1 to 4 patches/section) at 25 days post-infection.
