We therefore tested for the presence of African swine fever virus, pseudorabies virus, porcine reproductive and respiratory syndrome virus, classical swine fever virus, Japanese encephalitis virus, porcine circovirus type 2
, porcine circovirus type 3, porcine cytomegalovirus, and alphavirus by using the primers for those viruses (Appendix Table 2, https: //wwwnc.cdc.gov/EID/article/25/6/18-1983-App1.
Porcine circovirus type 2
is mainly linked to post-weaning multisystemic wasting syndrome (PMWS) and porcine dermatitis and nephropathy syndrome (PDNS), as well as reproductive disorders, including fetal mummification (ASANOME et al., 2008; MAES et al., 2008; MADSON et al., 2009).
Changes in CD4+, CD8+, CD4+ CD8+, and immunoglobulin M-positive peripheral blood mononuclear cells of postweaning multisystemic wasting syndrome-affected pigs and age-matched uninfected wasted and healthy pigs correlate with lesions and porcine circovirus type 2
load in lymphoid tissues.
, swine infectious pathogens have greatly caught the attention of researchers from early 1990s when a lot of pig-producing countries experienced very huge economic losses as a result of emerging viral disease-causing agents such as Porcine circovirus type 2
The major viral pig pathogens are pseudorabies virus (PRV), Japanese encephalitis virus (JEV), classic swine fever virus (CFSV), porcine circovirus type 2
(PCV-2), porcine reproductive and respiratory syndrome virus (PRRSV), porcine parvovirus (PPV), foot-and-mouth disease virus (FMDV), porcine epidemic diarrhea virus (PEDV), and transmissible gastroenteritis virus (TGEV).

PPV is also shown to be an agent able to increase the effects of porcine circovirus type 2
infection in the clinical course of postweaning multisystemic wasting syndrome , which is a significant disease in global swine production .

(PCV2)," Veterinary Microbiology, vol.
Experimental investigations demonstrated the pathogenic effects caused by porcine circovirus type 2
, which were exacerbated by the administration of oil-adjuvanted mycoplasma vaccines.
su agente etiologico es el Circovirus porcino tipo 2 (2-4) que se ha relacionado con otras manifestaciones clinicas de importancia para la industria las cuales en conjunto se han agrupado con la denominacion de enfermedades asociadas al PCV2 (Porcine circovirus type 2
associated diseases, PCvAD).
