The risk of area-spread of porcine reproductive and respiratory syndrome virus (PRRSV) continues to be high in swine-dense regions potentially because of PRRSV shedding from large populations of growing pigs.
Porcine Parvo Virus new cluster found in Netherlands

Porcine Parvo Virus (PPV), a single-stranded-DNA virus, has been known for over 50 years and is probably the most important cause of reproductive failure worldwide1. For years PPV is controlled by vaccination in order to prevent the classical clinical signs of still born piglets and mummies that vary in size and stage of mummification. Apart from this, PPV infections also potentially cause return to estrus and birth of too small litter sizes1. Within PPV there is evolution2 and over time in Europe PPV strains are shifting from cluster A to cluster D3. Recently evidence for the presence of a cluster D strain in the Netherlands was found. This is a summary of the case and consequent findings.
Episode 4 - PCV3: Emerging pathogen or incidental finding?

“Our recent work demonstrated the presence of the PCV-3 genome within mild-to moderate histological lesions of aborted fetuses. This supports that PCV-3 should be considered as a potential causative pathogen for reproductive failure"
Innate and adaptive immunity responses of swine to PRRSV

We propose that the strong humoral immunity bias of the host response to PRRSV is mostly responsible for the difficulties in the development of a vaccine deemed effective in the field.

Detection of PRRSV-2 alone and co-localized with CD163 positive macrophages in porcine placental areolae
- September | Top publications
- Javier Barrera-Zarate et al.
The porcine epitheliochorial placenta creates a barrier for the transplacental transfer of some nutrients from the dam to the fetus, as well as feto-lethal viruses such as porcine reproductive and respiratory syndrome virus 2 (PRRSV-2).

Synergistic effects of sequential infection with highly pathogenic porcine reproductive and respiratory syndrome virus and porcine circovirus type 2
- Expertise article
- Fan P. et al.
Porcine reproductive and respiratory syndrome virus (PRRSV) is the causative agent of porcine reproductive and respiratory syndrome (PRRS) and porcine circovirus type 2 (PCV2) is associated with postweaning multisystemic wasting syndrome (PMWS) in pigs. Coinfection with highly pathogenic PRRSV (HP-PRRSV) and PCV2 in the field has recently become extensive in some Asian countries. A synergistic pathogenicity between PRRSV and PCV2 infections has previously been reported. However, the consequences of the sequential infection of pigs with these two viruses are unknown.
