Studies concerning PMWS rapid diagnostic tools and epidemiology
Proceedings of the 18th IPVS Congress, Hamburg, Germany, 2004 - Volume 2:807
PCV2 genome amplification and quantification was carried out in nasal, bronchial, tonsillar, fecal and urinary swabs and blood samples from 142 pigs sent to the Veterinary Diagnostic Service at the Universitat Autònoma de Barcelona with various clinical conditions. Tonsil, superficial inguinal lymph node, liver and spleen samples were investigated for PMWS lesions. Animals with characteristic PMWS lesions had significantly higher viral loads than animals without PMWS lesions. Bronchial swabs of pigs with PMWS lesions had significantly higher viral loads when compared to the that the other swabs. The results of this study strongly suggest the respiratory route to be the main route of excretion of PCV2. In addition, a strong correlation was found between viral load in all five excretion routes and viral load in serum.
