Porcine Circovirus Type 2 (PCV2): Pathogenesis and Interaction with the Immune System

Annual Review of Animal Biosciences, 2013
Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus–associated disease (PCVAD). The virus preferentially targets the lymphoid tissues, which leads to lymphoid depletion and immunosuppression in pigs. The disease is exacerbated by immunostimulation or concurrent infections with other pathogens.

Differential Effects of Porcine Circovirus Type 2 (PCV2) Vaccination on PCV2 Genotypes at Japanese Pig Farms

Journal of Veterinary Medical Science, 2010
Infection of pigs with porcine circovirus type 2 (PCV2) causes a variety of disorders collectively referred to as porcine circovirus associated diseases (PCVADs). PCV2 isolates can be classified into two major types: PCV2a and PCV2b. In the present study, effects of vaccination on antibody titers in sera, PCV2 viremia, and shedding of PCV2 in feces ...

Porcine circovirus type 2 (PCV2) infections: Clinical signs, pathology and laboratory diagnosis

Virus Research, 2012
Clinical signs and pathological features are still the corner-stones to suspect and diagnose overt disease associated with PCV2 infection. The clinico-pathological scope of this viral infection has been expanded over time. From the initial description of postweaning multisystemic wasting syndrome, some enteric, respiratory and reproductive disorders ...

Enhanced immune response to inactivated porcine circovirus type 2 (PCV2) vaccine by conjugation of chitosan oligosaccharides [PDF]

Carbohydrate Polymers, 2017
This study aimed to investigate the effect of chitosan oligosaccharide (COS) conjugation on the immunogenicity of porcine circovirus type-2 (PCV2) vaccine. Two conjugates (PCV2-COS-1 and PCV2-COS-2) were designed by covalent conjugation of an inactivated
