title: RNA-seq analysis reveals genes underlying resistance to porcine circovirus type 2 infection in pigs showing different disease responses
design: Ten weaned Yorkshire × Landrace (YL) 6-week-old (on average) pigs were randomly sampled and infected intramuscularly with 3mL (103.8 tissue culture infective dose 50/mL) of the PCV2-SD strain. At 35 days after infection, the pigs were killed. Total RNA was extracted from the lung tissues of four YL pigs. And equal amounts of RNA from each of the four samples were mixed to build the library.
