a
Skin test thickness was recorded at day 0 and day 3 following inoculation with PPD-A and PPD-B. PPD-B-specific increases in skin thickness at 72 h are shown (i.e., response to PPD-B minus the response to PPD-A).
b
For pathology scores, medians are shown; for CFU and skin test data, means are shown.
