Increase in antigen-specific IgG responses following skin test application

  • a Data are expressed as relative density units and were calculated by subtracting values obtained by MAPIA analysis of sera taken before the skin test (week 27) from values obtained post-skin test (week 31). The tuberculin skin test was performed during week 28. P values for differences between control and BCG-vaccinated animals were 0.730 for ESAT-6 (by an unpaired, two-tailed t test), 0.079 for MPB70, 0.013 for MPB83, and 0.495 for MBCF. For the latter three P values, an unpaired, two-tailed t test with the Welch correction was used.
