Frequency of Porcine circovirus 3 detection in serum of pigs with respiratory and digestive disorders

In 2015 a novel porcine circovirus (PCV), named as PCV-3, was found by next generation sequencing methods from animals with different disease conditions. Although its pathogenicity has not been clearly established yet, it has been linked with reproductive...

Mutations in antigenic sites of the hemagglutinin protein following influenza vaccination

In Europe, the most widespread method for controlling influenza A virus infections in piglets is implementation of sow vaccination programs to secure delivery of maternal derived antibodies to the new born piglets. However, recent studies have questioned...

Impact of PCV2 co-infection on replication level of a field vaccine-like PRRSV-1 strain

In pig herds, PRRSV is often associated with PCV2, this co-infection being one key factor leading to post-weaning multisystemic wasting syndrome (PMWS). Worryingly, association of a PRRSV modified live vaccine of Type 2 (MLV2) with PCV2 infection was also...

Is ORF5 nucleotide sequence analysis sufficient for tracing PRRSV-1 strains?

PRRSV causes the most significant swine disease worldwide and shows remarkable genetic variation. PRRSV genotyping is being performed mostly based on ORF5 and/or ORF7 sequence analysis. Recent papers indicate that recombination between PRRS viruses may...

Analysis of resilience markers in relation to abortion rate in pigs

The concept of Resilience is used to define the ability of animals to overcome internal and external stressors, such as pathogen challenges. In pigs, a number of genetic markers have been studied in relation to the response to infection with the porcine...

Molecular characterization of Rotavirus B and Rotavirus C strains isolated from neonatal diarrhea outbreaks in Catalonia

Rotaviruses B (RVB) and C (RVC) have been reported to cause neonatal diarrhea worldwide. Nevertheless, there are few reports concerning the molecular characterization of porcine isolates in Europe. The aim of this study was to deep-sequence and...

Analyses of tonsillar microbiome in PRRSV vaccinated vs. non-vaccinated gilts after experimental infection with two different PRRSV-1 field isolates

Tonsils are a reservoir for host-specific pathogens and commensal organisms, mostly bacteria and viruses. The resident tonsillar microbiome is assumed to interact with incoming pathogens by preventing colonization via competitive exclusion. The present...

Prevalence of PCV2 genotypes in oral fluid samples originating from German and Austrian pig fattening farms

Quantitative measuring of PCV2 in serum samples is the golden method for monitoring PCV2 infections in growing and finishing pigs. However, over the last years, oral fluid (OF) sampling has gained more attention since it´s less invasive and more animals...
