Measurement of IFN-γ secreted in whole blood exposed to mycobacterial antigens. Blood was stimulated with Pokeweed mitogen (PWM), PPDJ, or PknG. Cattle were categorized based on (a) prevalence of MAP infection on farms, (b) PCR diagnosis of faecal shedding of MAP, and (c) serotype according to IDEXX ELISA. Bars are representative of the mean ± SE.
