Porcine circovirus type 2 blocks immune activation of natural interferon producing cells.
VINCENT IE, SUMMERFIELD A, STEINER E, GUZYLACK-PIRIOU L, McCULLOUGH KC
In vitro tests were conducted in order to assess the effect of porcine circovirus type 2 (PCV2) on the immune activation of natural interferon producing cells (NIPC). The results showed that PCV2 could have negative effects on the immune response of NIPC...

Immunological longitudinal PMWS cohort study.
LAGAN TREGASKIS P, McNEILLY F, McNAIR I, CAPRIOLI A, DUFFY C, ALLAN G
This study aimed at determining whether there was a link between maternal antibodies to PCV2 and the susceptibility of piglets to PMWS. Five sows, about to farrow, from a Northern Ireland pig herd farm, affected by PMWS, were selected for this 3-month...

PCV2 infection dynamics in two farms: relationship with PMWS expression, mortality and weight.
LOPEZ-SORIA S, SEGALES J, NOFRARIAS M, SIBILA M, ESPINAL A, RAMIREZ H, MINGUEZ A, SERRANO JM, MARIN O, JOISEL F, CHARREYRE C
The aim of this study was to compare the effect of two prorcine circovirus type 2 (PCV2) infection dynamics on postweaning multisystemic wasting syndrome (PMWS). The study took place in two similar Spanish farms, free from porcine reproductive and respiratory...

A cohort study on time to PCV2 seroconversion in three post-weaning multisystemic wasting syndrome (PMWS) affected farms.
ROSE N, PENHARD A, EVENO E, BLANCHARD P, OGER A, GRASLAND B, JOLLY JP, JESTIN A, MADEC F
The risk of developing a postweaning multisystemic wasting syndrom (PWMS) seems to be higher when porcine circovirus type 2 (PCV2) seroconversion occurs early in the piglet life. This study aimed at identifying the risk factors leading to PCV2 seroconversion...

DE JONG MF, WELLENBERG GJ, ELBERS ARW
A case-control study, aiming at knowing better the protential risk factors for postweaning multisystemic wasting syndrome (PMWS) and porcine dermatitis and nephropathy syndrome (PDNS), was carried out with pigs affected or not by PMWS and PDNS. Potential...

Porcine circovirus type 2: enzyme-linked immunosorbent assay (ELISA) for the detection of antigen and antibodies in feces.
LOPEZ P, GUILLOSSOU S, DESHAIES E, BRAJON N, BESTUL K, LETERME S
The usual methods used to detect the presence of porcine circovirus type 2 (PCV2) in pigs have their limits. Two Enzyme-Linked Immunosorbent Assay (ELISA) tests were developed: an antibody-detection blocking ELISA and an anitgen-detection capture ELISA....
