VirologyPorcine Respiratory Disease Complex (PRDC)
DONE S, WHITE M
Porcine respiratory disease and complexes : the story to date.
In Practice, 2003, Volume 25, N?7, 410-414, 417
Respiratory diseases in pigs are not a novel issue that swine practitioners have to deal with. Clinical signs have not changed that much over the past decades, but new causal agents have been involved, new vaccines have been available and production methods have evolved. In the 80's, the major etiologic agents were bacteria (Pasteurella multocida, Mycoplasma hyopneumoniae, Actinobacillus pleuropneumoniae, etc.). In the 90's, porcine reproductive and respiratory syndrome virus (PRRSV) emerged and together with swine influenza virus these new components of PRDC became major sources of concern. Subsequently, porcine circovirus type 2 (PCV2) made its entrance and is currently the most important troublemaker since, to date, no vaccine against PCV2 is available.
