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.

In vitro techniques for starch digestion and glucose release may be a useful tool to predict glucose absorption in pigs.

The use of oat β-glucan may reduce the postprandial glycaemic index.

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.

Recent reports of isolation of methicillin-resistant Staphylococcus aureus (MRSA) from food animals have raised concern about the potential for foodborne transmission. This study evaluated the prevalence of MRSA contamination of retail pork from 4 Canadian provinces.

Stress caused by reduced space allocation may disrupt the cellular immune system in piglets and stimulate the releases of cortisol.

This study tested the hypothesis that late weaning and the availability of creep feed during the suckling period compared with early weaning, improves feed intake, decreases stress and improves the integrity of the intestinal tract.

Hulless barley in piglet diets may reduce Salmonella typhimurium transmission among penmates.

The aim of this study was to evaluate the effect of porcine recombinant somatotropin (rpST) administered to piglets during their first week of life, on metabolic and somatometric variables. A total of 220 piglets born from 40 hybrid Landrace x Large White sows were used.

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.

It was concluded that natural infection of PEDV in the pregnant gilts and sows caused a reduction of subsequent reproductive performance.

Pigs can become MRSA positive in the short period of time during transportation from the farm to stunning at the abattoir.

A longitudinal study of Clostridium difficile colonization in piglets was performed on a conventional swine farm in Ontario, Canada. Fecal samples were collected from 10 sows prior to their expected farrowing date, and then from all their piglets on days 2, 7, 30, 44 and 62 of life.
