Opis:
The aim of this article was to present selected papers regarding circovirus infections in swine and also swine influenza, raised during the 11th ESPHM in Utrecht. Issues connected with circovirus-related diseases focus on studies of virus genotypes distribution and determination of the dominant PCV2 genotype in different regions of Europe. Also the prevalence of PCV2 and PCV3, the frequency of co-infection with both genotypes and PCV3 infection related gastrointestinal and respiratory symptoms in swine in European countries, were presented and discussed. These works also discussed the possible interaction between PCV2 and porcine parvovirus PPV4, assessed the pressure of PCV2 infection in pigs of different age and the impact of vaccination protocols on virus excretion. There were studies presented on the differences of virus circulation in vaccinated and unvaccinated animals. Also clinical presentation of infections with different PCV2 strains was described. Much attention was paid to assessment of oral fluid examination in diagnostic procedure. Reports regarding swine influenza have focused on the analysis of various diagnostic methods, the assessment of influenza A virus (IAV), its prevalence in piglets in the early and late nursery period and the analysis of IAV occurrence over the seasons. The diversity of influenza A viruses obtained from outbreaks and samples collected during epizootic monitoring in Spain and Portugal was also discussed, as well as the first case of the H1N1 pandemic subtype in a herd of pigs in Belgium.

Opis:
Swine influenza virus (SIV) of H1N1 and H3N2 subtypes are dominated in European pigs population. "Classical swine" H1N1 subtype was replaced by "avian-like" H1N1 subtype. It co-cir- culates with H3N2 reassortant possessing "avian" genes. In the present study, 41 SIV strains isolated from pigs with pneumonia, raised in 20 Polish farms, were identified and characterised. Since it was evidenced that isolates from the same geographic district and the same year of isolation are in 100% similar, 15 strains representing different district and different year of isolation were chosen to construct phylogenetic trees. Two genes, conservative matrix 1 (Ml) and the most variable, haemagglutynin (HA), were sequenced and subjected into phylogenetic analysis. The results of the analysis confirmed that "avian-like" swine H1N1 strains evolved faster than classical SIV strains. HA gene of these isolates have been derived from contemporary strains of "avian-like" SIV. In contrast, the Ml gene segment may have originated from avian influenza viruses. H3N2 strain is located in swine cluster, in the main prevalent European group of H3N2 isolates called A/Port Chalmers/l/73-like Eurasian swine H3N2 lineage, which has evolved separately from the human H3N2 virus lineage around 1973.
