IFNγ responses in plasma from heparinized blood stimulated in M. bovis-infected red deer (n = 15) presented as mean (±SD) of the optical density at 450 nm (OD450nm) to Pokeweed mitogen (PWM), negative control (phosphate-buffered saline, PBS), bovine and avian purified protein derivatives (PPD), p22; early secretory antigenic target-6 kDa and culture filtrate protein 10 (ESAT-6/CFP-10), Rv3615c and Rv3020c. *Statistically significant differences (p < 0.05) observed at specific time points since M. bovis infection in comparison to pre-inoculation values
