Fig. 2. Post-vaccination frequencies of Mycoplasma hyopneumoniaespecific
IFN-g secreting cells in PBMC of vaccinated (A, B and D
Groups) and non-vaccinated control (C) pigs. Data are expressed as
number of IFN-g secreting cells (SC) per million of PBMC (IFN-g SC/106
PBMC) and each value represents the mean response standard deviation
(values with different letters are significantly different between groups;
p < 0.05).
