Transmission of PCV2: Comparison of shedding patterns between PCV2a and PCV2b, evaluation of routes of transmission (fecal, oral, nasal, mechanical) and understanding the roles of spray-dried plasma and transport vehicles
July 22, 2009By Tanja Opriessnig
Temporal evidence correlated the emergence of PCV2b in the U.S. in 2005 with more frequent and severe porcine circovirus associated disease (PCVAD) cases. Information on the quantity and duration of...
