CD4 and infection: Erdman infected mice only in one of three experiments (S4 Fig).The TB10.474−88-specific CD4 T cell response was of similar magnitudeafter 667 or Erdman infection in all experiments (S4 Fig).Thus, these data show that 667 infection elicits a hierarchy of Mtb-specific CD8T cells that quantitatively differs from the reproducible hierarchy elicited byErdman infection in C57BL/6 mice.
