^a Serum protein profiles of animals in groups with the same code have been clustered for statistical analysis.

Different comparisons (A-H) were carried out, including serum protein profiles of animals from different infection groups and/or time points after infection. SELDI-TOF-MS profiles were obtained from three week old piglets that were experimentally infected with either a combination of PCV2 and PRRSV (PCV2/PRRSV), PCV2 and PPV (PCV2/PPV), or phosphate buffered saline (controls). Statistical analyses were based on data from day five post infection (p.i.), day 19 p.i., or data from both days combined as indicated in the table.
