    Porcine circovirus type 2 (PCV2) has emerged as one of the most important pathogens affecting swine production globally. Preclinical identification of PCV2 is very important for effective prophylaxis of PCV2-associated diseases. In this study, we developed an ultrasensitive nanoparticle DNA probe-based PCR assay (UNDP-PCR) for PCV2 detection.

  • Development of luciferase-linked antibody capture

    2018-11-16 · Early detection of porcine reproductive and respiratory syndrome virus (PRRSV) infection of swine is necessary to control this devastating disease. By monitoring host serum antibodies to viral antigens, early virus detection within herds is feasible. In this study, recombinant antigens were generated using recombinant DNA techniques to fuse PRRSV structural protein (N) or nonstructural …

    2014-9-24 · These ?ndings also suggested that single infection and co-infection of PCV2 and PRRSV might play an important role in porcine circovirus disease and reproductive failure. According to current knowledge of PCV2, PCV2 mainly infects lymphoid organs of pigs, resulting in the reduction of T and B lymphocytes and the increase of the monocytes and macrophages in peripheral blood and lymphoid …

It was worth noting that the positive rate of swine (59.11%) is much higher than the wild boar (18.33%) (Fig. 6). This suggests that differences between species and feeding conditions may affect PCV3 infection.
