Efficacy of a novel vaccine against porcine reproductive and respiratory syndrome virus (PRRSV) in neonatal piglets

PRRSV is still one of the most important viruses in the global swine industry and is often controlled by the use of modified live virus (MLV) vaccines in sows and piglets. Recently, a novel MLV for active immunization of clinically healthy piglets from...

Case study of PRRSv eradication by combining a MLV and KV PRRS vaccine on a Hungarian swine farm

PRRS to control in the modern swine industry. The clinical impact has not declined since the appearance in the early 90’s. More and more countries are working on control or even eradication of the virus. Hungary started in 2014 with a national PRRS...

Porcine Respiratory and Reproductive Syndrome (PRRS) control in 6 Fattening to Finish (FF) herds: Benefit of a whole herd approach

PRRS control remains a challenge and needs a whole herd approach to be successful. The aim of this study was to evaluate the benefit of the “5-step” process, which has been developed by Boehriger Ingeheim (BI), to control PRRS in 6 French FF herds.

PRRSV1 infection impact in the intestinal microbiome composition: a comparative study with strains of different virulence

Porcine reproductive and respiratory syndrome virus (PRRSV) infection is characterised by respiratory lesions, viral replication in alveolar macrophages and lymphoid organs and a strong early local inflammatory response together with a loss of the global...

DEEP-SEQUENCING CHARACTERIZATION OF TWO ROTAVIRUS A OUTBREAKS IN SUCKLING PIGLETS IN CATALONIA REVEALS A HIGH FREQUENCY OF RECOMBINATION EVENTS

Group A rotaviruses are one of the main causes of diarrhoea in pigs worldwide. In the present study, two outbreaks of diarrhoea in suckling pigs were investigated. Four rotavirus A isolates were deep sequenced and analysed to characterize the genetic diversity and identify recombination events.

PORCINE CIRCOVIRUS 2 WITHIN-HOST VARIABILITY, CO-INFECTION AND RECOMBINATION UNDER A NATURAL INFECTION SCENARIO

Porcine circovirus 2 (PCV2) is a virus characterized by high evolutionary rate, which promotes the potential emergence of different genotypes and strains. Despite the likely relevance in the emergence of new PCV2 variants, the subtle evolutionary patterns of PCV2 at individual-host level or over short transmission chains are still largely unknown.

DIVERSITY OF PRRS STRAINS CIRCULATING IN CANADA

PRRS sequencing is widely used and considered essential for the control of PRRS in Canada. Through several signed agreements, a structure was put into place and has allowed achievement of near real-time transfer of all sequences to our research team from 3 different laboratories in Quebec.

PRRS VIRUS SURVEILLANCE; ROLE OF VIRUS SEQUENCING AND VIRUS DETECTION BY PCR

Porcine reproductive and respiratory syndrome (PRRS) is a highly infectious disease, endemic in pigs throughout the world. PRRS is caused by a single stranded positive-sense RNA enveloped virus with a high mutation rate leading to greater heterogeneity of the nucleotide sequence between individual strains.

THE USE OF ROUTINE SEQUENCING ACTIVITY TO MONITOR THE EPIDEMIOLOGICAL TRAJECTORIES OF PRRSV IN ITALY

Porcine reproductive and respiratory syndrome virus (PRRSV) is a major threat to European swine production and Italian pig industry. Viral evolution analysis in terms of genetic variability over time and space is one of the challenging issue in the PRRSV control mostly in swine production area characterized by high pig density, fragmentation of the production chain and lack of high biosecurity levels.

FULL GENOME CHARACTERIZATION AND PREVALENCE OF PORCINE CIRCOVIRUS TYPE 3 ISOLATES FROM GERMAN FATTENING FARMS

Recently a novel porcine circovirus called porcine circovirus type 3 (PCV3) was reported from the Americas, Asia and Europe. PCV3 was detected with high prevalence in Polish farms, but to date no genome sequences were available from European PCV3 strains. The present study was performed to estimate the PCV3 prevalence in German fattening farms and to further characterize available PCV3 isolates.

DEVELOPMENT OF A REAL-TIME RT-PCR FOR DIFFERENTIAL DETECTION OF REASSORTANT H1N2 (H1N2R) SWINE INFLUENZA VIRUS

Endemic swine influenza virus (swIAV) strains including H1avN1, H1huN2 have been circulating in Great Britain (GB) for decades. In 2009, H1N1pdm09 became the dominant strain detected followed by H1N2 and the rapid decline of H1avN1 detections. An H1N2-H1N1pdm09 virus reassortant was detected in 2010; comprising H1 haemagglutinin (HA) and N2 neuraminidase (NA) surface glycoproteins with the H1N1pdm09 internal cassette.

CHANGES OF T AND B LYMPHOCYTES IN TISSUES AND BLOOD OF PIGS EXPERIMENTALLY INFECTED WITH AN ITALIAN HIGHLY PATHOGENIC PRRSV-1.1 ISOLATE

Highly pathogenic (HP) PRRSV recently emerged in Europe. The disease is characterized by high fever and respiratory distress in young pigs and high mortality rates and reproductive failure in sows. HP-PRRSV isolates can alter the pathological outcome differently from “conventional” PRRSV, in terms of more severe clinical signs and more intense dysregulation of cellular immunity.

1ST CASE REPORT: REPRODUCTIVE PERFORMANCE IMPROVEMENT AFTER PCV2 SOW VACCINATION IN SPAIN

PCV2 can be associated with reproductive failure and cause infertility and increased rates of mummified, macerated, stillborn and weak-born piglets. The aim of this study was to determine the impact of PCV2 sow vaccination on several reproductive parameters in a Spanish sow herd.

IMPROVEMENT OF REPRODUCTIVE AND PRODUCTIVE PERFORMANCE AFTER PRRS CONTROL PROGRAM IMPLEMENTATION IN SPAIN

Controlling this disease in large production systems is challenging. This is a summary of an 18 months field trial designed to evaluate the impact of the 5 step process approach using Reprocyc PRRS EU® and PRRSFlex EU® (Boehringer Ingelheim Vetmedica GmbH), a modified-live type I PRRS virus vaccine, on control of heterologous PRRSV in a commercial herd, assessed by live animal performance.
