rCap expressed in T. ni larvae could be a cost-effective PCV2 vaccine candidate to be tested under field conditions.

We performed a comprehensive analysis of innate and adaptive immune responses in dual-virus infected pigs to understand whether a pre-existing immunomodulatory respiratory viral infection affects the overall immunity to a subsequent porcine respiratory coronavirus (PRCV) infection in pigs.

Salmonella enterica subsp. enterica serovar Typhimurium was isolated from diarrheic piglets in 2 periods, 2000–2001 (n = 25) and 2005–2006 (n = 17). To compare the characteristics of the isolates collected during the 2 periods, all isolates were tested for antimicrobial resistance, the presence of virulence genes, and pulsed-field gel electrophoresis (PFGE) patterns.

In this study we investigated the HEV prevalence in Italian pigs displaying different pathological lesions, possible risk factors related to the infection, and the possible relations occurring between HEV and other concomitant pig pathogens.

Porcine circovirus type 2 (PCV2) is the causative agent of postweaning multisystemic wasting syndrome (PMWS). In this study, 38 PCV2 cases obtained from different pig farms with different health conditions in Republic of Korea were sequenced and analyzed.

The lymphatic organs of 50 pigs from a total of eight farms located at different sites in the epizootiological region of North Bačka County were studied to obtain data on the prevalence of circoviral infections in Serbia.

The purpose of this study was to determine the occurrence and genotypic relatedness of Salmonella enterica isolates recovered from feed and fecal samples in commercial swine production units.

To investigate the role of IFN-α in influenza, the swine IFN-α neutralizing monoclonal antibody (Ab) K9 was applied in a swine model of influenza A virus infection. First, the optimal dose and route for administration of the IFN-α neutralizing Abs was determined. Based on those results, the effect of the Abs on a swine influenza virus infection was investigated.

In this work, we produced 15 recombinant virulence-associated trimeric autotransporters (VtaA) passenger domains and looked for the presence of antibodies directed against them in immune sera by immunoblotting.

The primary objective of this study was to assess the prevalence of intrauterine PCV2 infection in clinically normal newborn piglets in conventional pork production facilities.

Swine workers had serologic evidence for infection with both swine and human influenza viruses and were exposed to diverse influenza virus strains circulating in pigs. Influenza virus surveillance among pigs and swine workers should be encouraged to better understand cross-species transmission and diversity of influenza viruses at the human-swine interface.

The objective of this study was to assess in pigs the pathogenicity and virulence of 3 strains of Salmonella spp capable of causing atypical salmonellosis in cattle.

E. coli played a significant role in the aetiology of pyelonephritis. Neutrophils were involved in the first line of defence. CD3ε T-lymphocytes were involved in both the acute and chronic inflammatory response while a humoral immune response was most pronounced in later inflammatory stages. The observed renal lesions correspond with an ascending bacterial infection with presence of intra-renal reflux.

Animals firstly infected with SwH1N1 virus and latter infected with pH1N1 exhibited undetectable viral RNA load in nasal swabs and lungs after challenge with pH1N1, indicating a cross-protective effect between both strains.

Porcine reproductive and respiratory syndrome (PRRS) and Mycoplasma hyopneumoniae (M hyo) are re-emerging diseases of pigs and growing threats to the global swine industry. For sustainable disease control, it is critical to prevent the spread of these pathogens between pig populations; therefore, a clear understanding of the role of aerosol transmission is needed along with information on how to reduce this risk.

Conventional serum storage protocols (freezing or refrigeration at 4°C) preserves PRRSV and anti-PRRSV antibody in oral-fluid diagnostic samples without the use of preservatives.
