Epidemiology and transmission of porcine circovirus type 2 (PCV2)
Virus Research, 2012 PCV2 has been highly prevalent in the pig population for decades, prior to the emergence of associated clinical disease manifestations that severely affected the pig production worldwide in the late 90s. PCV2 can be further subdivided into several genotypes.

Effect of porcine circovirus type 2 (PCV2) vaccination on PCV2-viremic piglets after experimental PCV2 challenge [PDF]
Veterinary Research, 2014 Abstract The objective of this study was to evaluate the effect of porcine circovirus type 2 (PCV2) vaccines on PCV2-viremic and -seropositive piglets born from naturally PCV2-infected sows against postnatal PCV2 challenge. The experimental design was aimed at mimicking commercial swine rearing conditions to evaluate the response of the PCV2 ...

Effects of Porcine Circovirus Type 2 (PCV2) Maternal Antibodies on Experimental Infection of Piglets with PCV2 [PDF]
Clinical and Vaccine Immunology, 2005 ABSTRACTTo determine the effects of porcine circovirus type 2 (PCV2) maternal antibodies on and response to experimental PCV2 infection, 24 piglets were divided into four groups on the basis of the enzyme-linked immunosorbent assay titers of PCV2 maternal antibodies: group A (n= 6; sample/positive [S/P] ratio, <0.2), group B (n= 5;S/Pratio, >0.2 ...
