Table 2. Viral DNA load in mouse serum measured by real-time PCR.

Group	No. of mice with viremia/no. tested (mean log PCV2 load ± SD) after PCV2 challenge a
Cap/2	6/6 (5.1 ± 1.6)
Flagellin-Cap/2	3/6 (3.6 ± 1.5) *
Cap/10	3/6 (4.6 ± 1.8)*
Flagellin-Cap/10	1/6 (3.2)*
Unchallenged control	0/6 (0)
Challenged control	6/6 (5.8 ± 1.2)

^aAsterisks within columns represent significantly different PCV2 loads between the flagellin-Cap fusion or Cap protein-vaccinated and non-vaccinated challenged mice after challenge (p0.05). A load value of 0 is equal to 1 000 copy per milliliter.
