EVALUATION OF THE SURVIVAL OF VIRAL PATHOGENS IN CONTAMINATED FEED INGREDIENTS USING TRANSBOUNDARY SHIPMENT MODELS

Introduction: This study evaluated survival of important viral pathogens of swine or their surrogates in contaminated feed ingredients during simulated transboundary transportation.  Based on global significance, 11 viruses were selected, including Foot...

SURVEILLANCE OF SWINE INFLUENZA VIRUSES (SIV) IN EUROPE 2015-2017 -AN UPDATE-

Influenza A virus infections causing economic losses are widely spread among swine populations worldwide. In Europe, over the past decades, four lineages of reassortant viruses between avian and human viruses have formed (H1N1av, H1N2hu, H3N2,...

SYRINGES PRRS MLV PCR POSITIVE UP TO 3 WEEKS AFTER USE FOR VACCINATION

Introduction In a Dutch endemic PRRSV infected sow herd – 1000 sows and weaners – in periodic PCR monitoring in non PRRS vaccinated piglets PRRSV was shown, ORF5 99% homologous to the vaccine strain used before. Possible infection routes were...

NEW STRATEGIES FOR SAMPLING PIGLETS

Introduction Several techniques have made diagnostics for PRRSV (porcine reproductive and respiratory syndrome virus) easier and cheaper (e.g. oral fluids, blood swabs or pooling samples). However, there are still opportunities for newer strategies to...

MOLECULAR IDENTIFICATION OF PORCINE CIRCOVIRUS TYPE 3 (PCV3) INFECTIONS ON COMMERCIAL PIG FARMS IN SPAIN

Two species of Porcine Circovirus (PCV) are well studied at date; PCV1 which is considered nonpathogenic and PCV2 that causes significant economic impact in swine industry worldwide. Recently, a new circovirus named PCV3 has been discovered in sows affected by PDNS and reproductive failure in USA and China. However, there is still sparse information about this virus. In this study we develop a qPCR assay for detection of PCV3 and perform a preliminary evaluation of this agent in Spain.

ILL-THRIFT IN WEANERS

A pig unit in Ireland expanded to 1000 sows within a year. Piglets are vaccinated against PCV-2 and EP. The breeding herd is vaccinated against PRRSv with a MLV. Weaner pigs are overstocked. There is an increase of weaners losing their body condition and abdominal panting. Wean to finish mortality ranges from 10 to 15%.

PRESENCE OF ROTAVIRURUS TYPE C IN NEONATAL DIARRHEA. PRELIMINARY RESULTS

Rotavirus is a major cause of diarrhea in piglets. Rotavirus type A is the most prevalent, but other rotavirus types have been described. Rotavirus type C is the second in prevalence but its implication in digestive process could be underestimated. The objective of this study was evaluating the presence of Rotavirus type C in neonatal diarrhea on commercial pig farms in Spain.

Congenital tremor Type A-II in newborn piglets is caused by transplacental transmission of a novel pestivirus

Congenital tremor is a well-known phenomenon in newborn piglets. It is characterized by tremors of the head and limbs that vary in severity, but are reducing or even absent during sleep. They last for several weeks to months but decrease in severity as the pigs grow older. Historically, congenital tremor has been classified as type A, with defined pathological characteristics and partially known etiology, or type B, with unknown etiology.

Could avian H9N2 influenza viruses become a threat to swine? Lessons from experimental studies in the pig.

It is a classical but unproven hypothesis that pigs can serve as intermediate hosts between birds and humans in the generation of novel pandemic influenza viruses. Yet the single pandemic virus of likely swine origin is the 2009 pandemic H1N1 virus (2009 pdm), a virus with genetic components of swine, human and avian origin (reassortant).

PRRSv INFECTION BY SEMEN IN A PIG UNIT IN NORTHERN IRELAND

PRRSv is enlisted as a Notifiable Disease in Northern Ireland (The Diseases of
Animals –Northern Ireland- Order 1981) after it was first diagnosed in 1997. The
prevalence of infection in 2011 was 36.6% of the Northern Irish pig producers.
In April 2013, the main boar stud of the island, located in the Republic of Ireland, was
diagnosed with PRRSv infection. This stud was supplying semen to around 70% of
producers in the whole island.
