Porcine Health Management

Porcine circovirus type 2 (PCV2) is an economically important swine pathogen causing a wide range of clinical problems, collectively named Porcine Circovirus Diseases (PCVD). Since the discovery of the virus, 2 major genotype shifts have been described....

Influenza A Virus - Swine (IAV-S) is present in pigs worldwide. In contrast to the general perception that IAV-S is predominantly a disease in finishing pigs, recent research has observed continuous circulation of IAV-S among piglets during the...

Alternative diagnostic sampling for detection of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) might be advantageous with respect to easy transportation (dry swabs) or animal friendly stress less sampling without the need for fixation....

Weaknesses in feed mill biosecurity may serve as an entry point for porcine viruses into the swine feed supply and subsequently impact herd health.

PRRS is an economically important swine disease and piglet vaccination is being increasingly used in control programs. The objective of this field trial was to assess the impact of a new PRRS piglet vaccination program at around 2-3 days of age (D) in a...

Knowledge on the pathogenic charateristics of different genotypes/strains of PCV2 is important for evaluating vaccine efficacy. Our recent survey indicated that PCV2a, PCV2b, and PCV2d genotypes are circulating in Europe. The aim of this study was to...

The emergence and spread of porcine respiratory coronavirus (PRCV) during 1980s, resulted in an endemic manifestation of the infection in most European countries. Due to negligible imports of live pigs to Norway, the commercial Norwegian pig population is...

Porcine reproductive and respiratory syndrome virus (PRRSV) is still one of the economically most important viruses often combatted by the use of modified live virus vaccines (MLV).The aim of the present study was to test the efficacy of a PRRS MLV...

Outbreaks caused by very virulent PRRSV strains have been reported worldwide. The aim of the present study was to evaluate the immunopathogenesis of lung lesions caused by two PRRSV1 strains, one of low and the other of high- virulence.

Influenza A virus (IAV) subtypes H1N1, H1N2 and H3N2 circulate in swine herds in Belgium. Shortly after the emergence of the human pandemic H1N1 2009 IAV (pdmH1N1(2009)), variants of this strain occurred in global swine populations. Here we describe the...

Intensive pig husbandry offers optimum transmission conditions for pathogens. Especially undetected influenza A virus (IAV) infections cause immense financial losses in pig production and poses a risk to human health. Correlation of clinical signs and...

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...

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...

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.

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...
