Shedding and Infection Dynamics of Porcine Circovirus Type 2 (PCV2) After Natural Exposure
A.R. Patterson, D.M. Madson, P.G. Halbur and T. Opriessnig
The objective of this study was to determine the amount of porcine circovirus type 2 (PCV2) shed in nasal, oral and fecal secretions over time following natural PCV2 infection. Fecal, oral and nasal swabs and blood were collected at regular intervals starting at 28 days post farrowing (DPF) until 209 DPF from four pigs naturally infected with PCV2. PCV2 DNA was detected in all sample types. There were no differences in the amount of PCV2 DNA present in different sample types over time. PCV2 DNA was detectable in sera and secretions in pigs through 209 DPF. Natural exposure to PCV2 results in a long term infection and PCV2 is shed in similar amounts by nasal, oral and fecal routes.
