New knowledge on the pandemic H1N1 virus in pigs

CReSA scientists have published a study to determine the relevance of human H1N1 virus in pigs previously infected with circulating influenza virus. Thanks to that, important questions have been answered that threatened the pig sector in Europe.

The Veterinary Research journal recently published an article by CReSA scientists and showing that pigs exhibit some immunity to the pandemic virus A (H1N1) 2009 if they have previously been infected with other influenza viruses circulating in the herds, in this case, the European H1N1.

What will happen in the Spanish and European farms, which have a high prevalence of swine flu, if an outbreak of human H1N1 pandemic virus happens? This is the question which international agencies faced with a threat of great potential and that this research has answered. CReSA’s scientists conducted a study with different groups of pigs trying to analyze whether an infection of swine influenza A (H1N1) causes some immunity to subsequent infection of H1N1 human pandemic virus. The results were very mild pulmonary lesions and a subsequent increase in specific antibodies in the animals receiving both viruses. Therefore, there was a cross-protective effect among strains.

This study has allowed us to know a little more about the pandemic virus and how it may affect the pig sector.
