Prevalence and diversity of swine influenza virus in Europe

G.E. Martin

I. Díaz

Genetic and antigenic diversity of influenza virus should be understood as something dynamic and constantly evolving. So, it is crucial to encourage active surveillance of SIV in order to improve our knowledge of the SIV strains present in the European pig and their particular prevalence and impact in swine production.

The role of pigs in the generation of new strains of influenza

G.E. Martin

Pigs can act as a source of new influenza strains with zoonotic potential, but the increase of the genetic diversity of the swine influenza viruses is largely due to the introduction of influenza strains of human origin. Therefore, it is highly recommended that all staff that has frequent contact with pigs should be vaccinated against influenza.

Flu productive impact

There are many open topics, such as: 1) what is the impact of the disease in endemic situations at the reproductive level (irregular return to estrus / fertility), especially in gilts; or 2) what is the productive impact in farrowing units, especially when we know that suckling piglets can play a role as a reservoir of the virus in an endemically infected farm.

Evolution of swine influenza viruses and its impact on antigenic cross-reactivity

G.E. Martin

I. Díaz

Swine influenza viruses are diverse at genetic and antigenic level, resulting in a limited cross-reactivity in viruses sharing a common ancestor or belonging to a same subtype.
