Sampling breeding herds and suckling-age piglets could serve as a valuable alternative to traditional surveillance schemes.

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

This study concluded that Laiwu had stronger capacity of immunological stress resistance and next was Lulai among three breeds. Chromium yeast helped piglets relieve immunological stress.

No dam related risk factor for colonisation status of litter or piglets within litters could be identified.

This study is the first to show an impact of PRRSV/SIV co-infection and superinfections in the cellular and tissue immune response at the molecular level.

The within-flow prevalence was reported to be variable (1% to 20%), with cases reported in five provinces and 11 states.

Different factors were specifically associated with either H1N1 or H1N2 SIV infections.

Analysis of ORF5 and full-length genome sequences of PRRSV isolates of genotypes 1 and 2 retrieved worldwide provides evidences supporting that recombination is a common phenomenon and may produce mosaic isolates.

Oral fluids can be used as a sample type to accurately detect the presence and circulation of PEDV in pig herds.

Organic dust extract exposure negatively affects pig macrophage activation and function, potentially enhancing host susceptibility to a variety of respiratory infections.

Phylogenetic analysis revealed that they belonged to the lineages ‘‘Avian-Like’’ H1N1, ‘‘Human-Like’’ H3N2, and ‘‘Human-Like’’ H1N2

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.

Therefore, the aim of the present study was to investigate the frequency of M. hyopneumoniae infections in suckling pigs of endemically infected herds.

Plant extracted polyphenols may be a natural source additive to overcome diarrhoea in weanling pigs.

Helicobacter suis is present in US pigs and may be relevant to pig health and production

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