Abstract
To analyze serum proteomics differences between normal and foot and mouth disease virus (FMDV)-infected piglets, an analytical method based on liquid chromatography with tandem mass spectrometry (LC-MS/MS) was used. Samples of venous blood were collected before and after FMDV infection and high abundance serum albumin was removed using a commercial kit. After trypsin digestion, serum samples were processed with LC-MS/MS. Proteins were identified by peptide mass fingerprinting. We found that apolipoprotein A-IV precursor, haptoglobin and probable chemoreceptor glutamine deamidase cheD appeared after FMDV infection in the same piglet. This is believed to be the first time that serum proteomics analysis by LC-MS/MS after FMDV infection has been performed, and our results may provide further information about biomarkers for early diagnosis of FMD in piglets.
