Porcine Health Management

The objective of this study was to evaluate the effect of a PRRS vaccination under field conditions at a PRRS positive farm with finisher pigs.

The influenza A virus (IAV) subtypes H1N1, H1N2 and H3N2 circulate in domestic pigs at variable rates in The Netherlands. Following the emergence of the human pandemic H1N1 2009 IAV (H1N1pdm), variants of this virus occurred in global swine populations. Here we describe the detection of IAV including H1pdmN1 and H1pdmNx in swine farms in The Netherlands in the period April to September 2017.

Neonatal diarrhea is one of the major causes of economic losses in porcine production and many infectious agents can be involved. In this study, outbreak cases of diarrhea were tested for a panel of major enteric pathogens in suckling piglets in Spain.

PUCS sampling has shown to be a convenient method to detect vertical transmission of PCV2 from viraemic dams to their offspring. Furthermore, vaccination of sows with Ingelvac CircoFLEX® has shown to reduce vertical transmission and improve the reproductive performance of the sow herd.

Monocytic cells are important target cells for porcine circovirus type 2 (PCV2) in pigs. They can take up PCV2. However, the mechanism of this process and the outcome were still not elucidated.

The objective of this study was to evaluate the dynamics of different pathogens on Dutch pig farms with PRDC problems before, at and after the start of cough by using oral fluids with PCR testing for different pathogens.

The objective was to investigate the prevalence of different pathogens in Dutch pig farms with PRDC problems by using oral fluids (OFs) with PCR testing.

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) 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.

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 (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.

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.

PRRSV causes significant economic losses to the global swine industry. The aim of this study was to evaluate the ID and IM PRRSV MLV vaccination in suckling piglets under field conditions.

Introduction Highly virulent PRRSV strains causing severe disease have been reported in Europe, Asia and North America, associated with high fever, anorexia, severe lung lesions and high mortality. The aim of this study was to characterise the impact of...

Introduction   PRRSv control protocol depends on infection dynamics in swine herds. Assessing stability in breeding herds is a main issue. The aim of this study was to compare the ability of three types of samples to detect PRRSv in pre-weaning...
