Experimental Porcine Toxoplasma gondii Infection as a Representative Model for Human Toxoplasmosis

Figure 2

T cell proliferation after stimulation with recombinant antigens from T. gondii. 1.5 × 105 PBMC/well from 8 pigs before infection (0 dpi) and day 28 post infection (28 dpi) were stimulated in triplicate with recombinant GRA1, GRA2, GRA7, GRA9, BAG1, or SAG1 (1 μg/ml) and T cell proliferation was determined via 3H-thymidine incorporation. Each dot represents one individual; black bars indicate mean counts per minute from all individuals tested; significant differences are marked with asterisks (, , and ).
