We speculate that co-infection with PCV2 and HEV may bring some negative effect on pig production and recommend that more attention should be paid to this phenomenon.

PCV2b was the predominant genotype in Croatia and has been linked to international trade as a route of introduction.

Even in the absence of clinical signs, growth rate and feed intake are likely to be reduced by L. intracellularis infections. There is a trend that also PCV2 infections can exert a similar negative influence.

Co-infection with PRRSV enforces clinical signs of PMWS, the influence of other viral co-infections is not clear.

These findings illustrate the importance of maternal infection, despite robust anti-PCV2 immunity, in early infection of newborn piglets.

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 findings of this study have implications for future PCV2 vaccine testing and administration strategies.

PCV2b challenge increases the expression of a large number of immune-related and pro-apoptotic genes mainly in MoDC, which possibly explain the increased inflammation.

One-dose vaccination of sows against PCV2 induces colostral antibody transfer.

In conclusion, placental transmission of PCV-2 from a non-immune sow to fetuses is possible when the infection of the dam occurs before gestation or after 62 days of gestation.

The vaccine may have the potential to serve as a vaccine aimed to protect pigs from developing PMWS.

Increasing numbers of L. intracellularis log10 bacteria/g faeces were significantly associated with decreasing average daily gain.

PCV2-lung disease is probably a negligible condition and porcine circovirus type 2 mainly contributes to porcine respiratory disease complex by means its systemic infection.

The aim of this study was to investigate whether PCV2 infection affects the efficacy of the LPC vaccine.

Under the study conditions, dam vaccination reduced PCV-2 viraemia in the offspring with colostrum access.

The findings of this study highlight the potential role of the immune status of the sow on the occurrence of PMWS.
