Field study confirms protection of piglets against porcine circovirus associated disease by vaccination with Porcilis® PCV

Intervet/Schering-Plough Animal Health announces today that a field trial with the single-dose subunit vaccine PORCILIS® PCV has confirmed that vaccination induces humoral and cellular immunity and protects piglets against the consequences of porcine circovirus-associated disease (PCVD).

The importance of porcine circovirus type 2 (PCV2) subclinical infection

Available data indicate that PCV2 has the ability to modulate the immune response, not only during the obvious overt disease but also in a subclinically infection.

Maternally derived antibodies at the time of porcine circovirus type 2 vaccination: does it matter?

One issue is to overcome maternal immunity, which is true for all PCV2 vaccines in the market, and another is whether the most from these vaccines is achieved independently of the PCV2 antibody titre at vaccination

A piglet claim for CIRCOVAC® in Europe

On November 29th 2010, CIRCOVAC was granted a European marketing authorization for use in piglets. CIRCOVAC is now the first PCVD vaccine available worldwide for the vaccination of both sows and piglets; it is registered in Europe, Brazil, Mexico and Thailand.

Porcine Circovirus remains in the spotlight of European researchers

The fourth edition of the European PCV2 Research Award sponsored by Boehringer Ingelheim saw a record number of applications showing the continued interest in Porcine Circovirus Type 2 (PCV2) research: 13 researchers from ten different countries submitted proposals.

Immunity conferred by an experimental vaccine based on the recombinant PCV2 Cap protein expressed in Trichoplusia ni-larvae

rCap expressed in T. ni larvae could be a cost-effective PCV2 vaccine candidate to be tested under field conditions.

United kingdom - VLA investigates PCV2 as cause of reproductive failure

The Veterinary Laboratories Agency (VLA) is to increase surveillance for PCV2 virus as a cause of reproductive failure in cases of abortion and stillbirth where no other infectious cause has been identified.

Genetic diversity of porcine circovirus type 2 from pigs in Republic of Korea

Porcine circovirus type 2 (PCV2) is the causative agent of postweaning multisystemic wasting syndrome (PMWS). In this study, 38 PCV2 cases obtained from different pig farms with different health conditions in Republic of Korea were sequenced and analyzed.

Distribution of Porcine Circovirus 2 Cap antigen in the lymphoid tissue of pigs affected by postweaning multisystemic wasting syndrome

The lymphatic organs of 50 pigs from a total of eight farms located at different sites in the epizootiological region of North Bačka County were studied to obtain data on the prevalence of circoviral infections in Serbia.

High prevalence of porcine circovirus viremia in newborn piglets in five clinically normal swine breeding herds in North America

The primary objective of this study was to assess the prevalence of intrauterine PCV2 infection in clinically normal newborn piglets in conventional pork production facilities.

China - PCV vaccine developed in Henan

A vaccine against porcine circovirus (PCV) has been successfully developed in Henan Province and granted the National Registration Certificate for New Veterinary Drug and the production approval document number as well as the approval to be marketed as a national-level new veterinary drug of the second category from the Ministry of Agriculture (MOA).

Canada - Economic impacts of Porcine Circovirus Associated Disease

This disease is costing the Canadian pork industry about 60 million dollars a year.

Sanitary Equilibrium: The role of PCV2 vaccines

The most common problems are due to interference with maternal antibodies and coincidence of vaccination with a recirculation of PRRS: viremic animals.

Pathologic and virologic findings in mid-gestational porcine foetuses after experimental inoculation with PCV2a or PCV2b

This study aims to determine the clinical and virological outcome of surgical inoculation of 55-day-old immuno-incompetent porcine foetuses with PCV2a or PCV2b.

Simultaneous detection of porcine circovirus type 2, classical swine fever virus, porcine parvovirus and porcine reproductive and respiratory syndrome virus in pigs by multiplex polymerase chain reaction

A multiplex polymerase chain reaction (PCR) was designed for the simultaneous detection of four viruses involved in reproductive and respiratory failure in pigs: porcine circovirus type 2 (PCV-2), porcine parvovirus (PPV), classical swine fever virus (CSFV) and porcine reproductive and respiratory syndrome virus (PRRSV).

Intervet/Schering-Plough animal health demonstrates efficacy of simultaneous use of circovirus and mycoplasma vaccines in swine

Simultaneous (mixed) use of existing swine vaccines against porcine circovirus 2 (PCV2) and Mycoplasma hyopneumoniae (M. hyo) from Intervet/Schering-Plough Animal Health in swine are as efficacious and safe as separate use of these vaccines.
