The vaccine program of this farm was PmA, PmD, APP2, App5 and MH and without any history of PCV2
and PRRS vaccination.
At that meeting, the FDA announced that Merck had recently notified the agency that PCV1 and PCV2
had been detected in that company's rotavirus vaccine, RotaTeq.
has been identified as a causal agent of a lethal wasting disease in pigs.
infection has been associated with granulomatous enteritis (KIM et al.
sin embargo la identificacion de los factores de riesgo que se relacionan con el desarrollo de la enfermedad no es totalmente clara y no en todos los casos se incluye el PCV2
como agente relacionado con el PMWS (12, 22-24).
On May 14, the FDA withdrew its suspension of Rotarix vaccine recommendation and pronounced both vaccines safe, even though both remain contaminated and safety data on PCV2
contamination of RotaTeq was not evaluated by the FDA advisory committee.
The effects of the PCV2
vaccine are likely to be seen this year.
Post weaning multisystemic wasting syndrome (PMWS) associated with PCV2
infection is the major disease affecting commercial herds of swine worldwide.
Comparison with other members of the Circoviridae demonstrated that RaCV shares the greatest sequence homology with canary circovirus (CaCV) and pigeon circovirus (PiCV) and was more distantly related to the beak and feather disease virus, goose circovirus, duck circovirus, and the 2 porcine circoviruses, PCV1 and PCV2
Recommend use of RotaTeq vaccine be suspended until Merck can guarantee it is free of PCV1 and PCV2
and other adventitious agents;
