Experimental co-infection of pigs with Bovine viral diarrhea virus 1 and Porcine circovirus-2.

The article shows the function of Bovine viral diarrhea virus (BVDV) in progression of Porcine circovirus-2 (PCV-2). Two studies were performed, where the first one involved vaccination of germ-free pigs vaccinated with different PCV-2 and BVDV viruses. The second study looked at cesarian-derived, colostrum-derived pigs that were vaccinated with the viruses. Results showed that BVDV and PCV-2 hinder growth and caused death of pigs through developing acute respiratory distress.
