Frequency of Porcine circovirus 3 detection in serum of pigs with respiratory and digestive disorders

In 2015 a novel porcine circovirus (PCV), named as PCV-3, was found by next generation sequencing methods from animals with different disease conditions. Although its pathogenicity has not been clearly established yet, it has been linked with reproductive...

Impact of PCV2 co-infection on replication level of a field vaccine-like PRRSV-1 strain

In pig herds, PRRSV is often associated with PCV2, this co-infection being one key factor leading to post-weaning multisystemic wasting syndrome (PMWS). Worryingly, association of a PRRSV modified live vaccine of Type 2 (MLV2) with PCV2 infection was also...

A phenotyping method to identify PRRSV-resilient sows in PRRSV-infected farms under epidemic and endemic scenarios

Porcine reproductive and respiratory syndrome (PRRSV) is a viral disease with negative impact on sow reproduction. A strategy to control this virus is to select animals more resilient to the infection. A key issue to deal with disease resistance is to set...
