Pig health

Hans Nauwynck defines himself as a veterinary virologist, a person who works in a laboratory setting, doing precise work, like a surgeon, aiming to gain a better understanding of how animal viruses interact with their target cells. But it is much more. His deep understanding of the biological behavior of viruses allows him to fluently explain many of the “whys” that are so important for a better understading of the pathogenesis of viral diseases and the development of effective control strategies.

PRRS control measures also reduce the opportunities for different wild-type viruses to recombine and create more aggressive strains.

Genetic mutation and evolution of PRRSV can occur across all genes. Unlike ORF5, which only represents about 4% of the PRRSV genome, NGS can recover a whole PRRSV genome to be used in epidemiological investigations.

The first three years of the Danish PRRS reduction strategy have shown that it is possible to control and reduce the prevalence of PRRS in Danish pig production.

In the first two months, the outbreak caused more than 600 abortions and more than 150 sow deaths, destroying the weekly batch structure.

We analyze the two most relevant respiratory viruses in the swine population.
