  1. 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.
  2. aThe pigs were inoculated with 105.3 TCID50 of PCV2 (group 1 and 2), 1 dose of LPC vaccine (group 1 and 3), and 106.8 TCID50 of wild-type CSFV (ALD) (group 1, 2, 3, and 4) at 0, 12, and 27 dpi, respectively. The PCV2 and wild-type CSFV loads in saliva were detected by real-time PCR or reverse transcription real-time PCR, respectively.
  3. bNumber of PCV2-positive animals/number of wild-type CSFV-positive animals/number of surviving animals.
