Abstract:
1. A method of determining whether a pig has received a commercial PRRSV modified live attenuated vaccine (MLV) comprising: a. obtaining a biological sample from an individual; b. contacting the biological sample with an antibody that binds to the N terminal region of the 2b protein of PRRSV to form a complex when there is an aspartic acid at position 9; wherein the position number of said PRRSV corresponds to the position number in SEQ ID NO:40; and c. assaying for the presence of said complex, wherein an aspartic acid at position 9 indicates that said pig has not received a commercial PRRSV modified live attenuated vaccine (MLV) and a tyrosine or glycine at said position indicates that said pig has received said MLV.
