Six 5-week-old porcine circovirus type 2 (PCV2)-free, cesarean-derived, colostrums-deprived (CDCD) pigs were inoculated intranasally with 106 TCID50 of PCV2. Four CDCD pigs were untreated cohabitants. Forty farm-raised pigs from two PCV2-contaminated herds were randomly selected for PCV2 trace investigations. Blood, nasal, oropharyngeal and fecal samples were collected from all tested pigs weekly. The PCV2 DNA shed at 6-11 and 7-12 weeks of age for PCV2-inoculated pigs and cohabitants, respectively. All the CDCD pigs exhibited seroconversion after PCV2 exposure. In the farm-raised animals, PCV2 shed at 9-15 weeks of age and seroconversion started at 11 weeks of age. Collectively, the pigs had a prolonged PCV2 shedding period following viral exposure, and growing pigs were the source of horizontal PCV2 transmission in PCV2-infected herds.
