PCV2: Porcine circovirus type 2; LPC: Lapinized Philippines Coronel; CSFV: Classical swine fever virus.
Group 1: PCV2-infected/LPC-vaccinated/CSFV-challenged; group 2: PCV2-infected/CSFV-challenged; group 3: LPC-vaccinated/CSFV-challenged, and group 4: CSFV-challenged.
^aThe pigs were inoculated with 10^5.3 TCID₅₀ of PCV2 (group 1 and 2), 1 dose of LPC vaccine (group 1 and 3), and 10^6.8 TCID₅₀ of wild-type CSFV (ALD) (group 1, 2, 3, and 4) at 0, 12, and 27 dpi, respectively.
