Projections of the 15 badgers on the two-dimensional space. The space was defined by principal component axes 1 and 2 (Factor 1 and 2) according to their type of response to treatment. Arrows reflect the direction and contribution to the axes of each of the seven parameters included in the principal component analysis (PCA). Confidence 95% ellipses are displayed. Post-mortem C/E cocktail refers to CFP-10 and ESAT-6 cellular immune response at post-mortem measured by ELISPOT. Post-mortem P22 refers to humoral immune response at post-mortem measured by ELISA P22. CFU: colony-forming units. HIMB: heat-inactivated Mycobacterium bovis vaccine.
