Porcine circovirus type 2 (PCV-2) is involved in several diseases named porcine circovirus-associated diseases and is transmitted by oro-faecal route. In this study we inoculated porcine-circovirus free piglets by mucosal routes (intratracheal or oro-nasal routes) with a plasmid carrying two copies of PCV-2 genomic DNA and compared the results to the intramuscular route. We observed that this PCV-2 naked DNA serves as template for viral replication and infectious PCV-2 particles are detected in the whole body after parenteral (intramuscular) or mucosal (intratracheal or oro-nasal) delivery. These results suggest that PCV-2 genome could play a role in in vivo transmission.
⺠PCV-2 naked DNA serves as template for viral replication after mucosal inoculation. ⺠Intramuscular route is more effective than mucosal route for PCV-2 DNA inoculation. ⺠Around 104 TCID50/g of tissue are produced 34 days after PCV-2 DNA inoculation.
