These results provide practical information for treatment of M hyorhinis infection in pigs.

The presence of pathogens in feral pigs in such close proximity to commercial piggeries could pose a biosecurity risk.

The aim of the present study was to determine risk factors for lameness development within the first days of group-housing, with a focus on housing conditions, management and post-mixing aggression in sows.

The survival of A. pleuropneumoniae was investigated under controlled laboratory conditions.

The goals of this study were to characterize influenza infections in Minnesota pigs and assess biosecurity measures used by swine workers.

Vaccination may affect strain diversity and immune escape through recombination and point mutation.

The findings demonstrate strong association between heavy metal tolerance and antimicrobial resistance, particularly among Salmonella serotypes important in public health.

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

Factors related to external and internal biosecurity and to the control of inside climatic conditions should be considered together when implementing programmes to better control SIV infections.

The total prevalence of PToV was 45% (9 out of 20 farms); it was the first detection of PToV in China.

A pre-infection of SJPL and PAM cells with App blocked completely PRRSV infection.

A review published by researchers of CReSA provides an overview of the current knowledge of virulence factors of H. parasuis.

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.

New Neonatal Porcine Diarrhoea Syndrome (NNPDS) is a newly defined syndrome, characterized by a treatment-refractory diarrhoea during the first days of life.

These studies demonstrate for the first time, to our knowledge, that a protein can function as a transactivator of ribosomal frameshifting.

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

The behavior of three antibiotics (bacitracin, chlortetracycline, and tylosin) and two classes of antibiotic resistance genes (ARGs), tet and erm, were monitored in swine manure slurry under anaerobic conditions.

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

The data collected in this study add new knowledge on this very important and difficult to control segment of the farm-to-fork chain.

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.

Biosecurity is a useful measure to promote the reduction of antimicrobial use in the pig industry.

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

Our results indicate that brucellosis infections in feral swine within the US are typically caused by B. suis.

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