DEVELOPMENT OF GB PIG DISEASE SURVEILLANCE DATA IN AN INTERACTIVE FORMAT FOR PIG VETERINARIANS AND OTHERS USING PRRS AS AN EXEMPLAR

An interactive tool displaying pig diseases diagnosed through the GB surveillance network was recently made available on-line. Development to allow more detailed interrogation of surveillance data is in progress and this study uses data from porcine reproductive and respiratory syndrome (PRRS) diagnoses as an exemplar.

PORCINE CIRCOVIRUS TYPE 3 (PCV3) IN POLAND - DETECTION AND GENETIC DIVERSITY

Porcine circovirus type 3 (PCV3) is a novel pathogen first discovered in 2016 in USA. PCV3 is suspected to be involved in numerous diseases, but its true role in pigs health is still unknown. The objective of this study was to investigate the prevalence and molecular diversity of PCV3 in serum samples collected from14 pigs farms from Poland.

CHARACTERIZATION OF ASTROVIRUS CAUSING GASTROENTERIC DISEASE IN PIGLETS IN ITALY BY A METAGENBOMIC APPROACH

Astroviruses are emerging viruses, Family Astroviridae, that infect mammalian and avian species. They are non-enveloped viruses with a single-stranded positive sense RNA genome. They are detected in the intestines and several other organs in diseased and healthy animals.

NOROVIRUS IN FAECES OF HEALTHY PIGS IN NORTH-EAST ITALY

Norovirus (NoV) has emerged has one of the major causative agents of non-bacterial, food- and water-borne gastroenteritis in humans all over the world. NoVs are classified into six groups (G), from GI to GVI, which are further subdivided into 30 genotypes. NoVs identified in human gastroenteritis cases are only GI, GII, and GIV. NoVs have also been isolated from several animal species, including pigs, dogs, cattle, rodents and lions.

MOLECULAR CHARACTERIZATION OF THE SPIKE GENE OF THE PORCINE EPIDEMIC DIARRHEA VIRUS IN MEXICO

In Mexico, the first suggestive outbreaks of the circulation of the porcine epidemic diarrhea virus (PEDV) were identified at the beginning of July 2013. The Spike protein is the most antigenic protein of the virus and the main target for developing a vaccine or diagnostic system.

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.
