  • a Five foals and five adult horses were infected intrabronchially with virulent R. equi, and serum and BLN cells were collected at 15 days postinfection. Five uninfected foals and five adult horses were used as controls.

  • b Symbols: *, significantly different coefficient of correlation between a given subisotype and IL-4 versus that of the same subisotype and IFN-γ (P < 0.05); †, statistically significant correlation (P < 0.05).
