Figure 1

Schematic illustration of the experimental protocol and ELISA of seroconversion prior to HP-PRRSV challenge. A. After piglets were housed, different vaccines (MLV, KIV, and IgM + KIV) were used to vaccinate animals via the intramuscular route using the indicated doses described in the Methods section. Blood and nasal swab samples were collected at the indicated times, and all surviving animals were necropsied at 21 dpi. B. After immunization of piglets with different vaccines, serum samples were collected weekly and examined to detect seroconversion using an IDEXX HerdChek PRRS X3 ELISA kit. All experiments were repeated at least three times for each serum sample. Data are expressed as the mean ± SD.
