Recently, PCV2 has been suggested as a pathogen able to induce diarrhoea in pigs, and PCV2-enteric disease (PCV2-ED) as a separate entity within porcine circovirus diseases (PCVDs) has been proposed.

Today, nearly all genetic suppliers of replacement breeding stock in North America are free of M.hyo.

As the Influenza A virus ecology has become more complex due to viral reassortment and mutation, so have the sample types and diagnostic tests available for detecting or diagnosing influenza infections in swine.

Estimated losses associated with M. hyopneumoniae alone and M. hyopneumoniae in combination with PRRSV were among the four health challenges with the highest estimated average loss for all pigs in the study population.

Cross-sectional sampling (different age groups during one herd visit) has the advantage that results are obtained quickly.

In the last 4 batches of weaned piglets, the farmer saw around 3% of anorexic and lethargic piglets. All the treatments he tried failed (amoxicillin or florfenicol injections), and finally the piglets died.

ASF spreads mainly through the movement of infected pork and other animal products, as well as live animals, which includes wild boar.

Four virus lineages, having clearly distinguishable HA, are currently co-circulating in European pigs and can be considered as enzootic viruses, even if their relative prevalence and level of incidence vary from one country to another.

ASF is now firmly established in some areas of the Caucasus and Eastern Europe, where it is causing considerable trade disruptions, plus having a devastating impact on small-scale pig farmers.

The first goal of the project is to control PRRSv-infections in order to produce negative offspring.

The interaction between M. hyopneumoniae and its host make M. hyopneumoniae one of the most important contributors to porcine respiratory disease.

Pathogens that are transmitted mostly through direct, pig to pig, contact are generally contained with today’s biosecurity programs and pig flow strategies. However, pathogens using multiple routes of transmission seem to evade standard biosecurity programs.

A risk of airborne transmission of PRRSV is real, and air filtration can significantly reduce its risk. Area regional approach on PRRSV control/elimination indicates our direction where we should move forward in future.

Despite the evident usefulness of laboratory diagnosis, we must not forget that a field necropsy allows us to us recover part of the loss caused by the death of the animal.

Recent reports still show high prevalence of the pathogen in most pig producing countries.

One of the challenges when conducting a disease elimination project is to ensure that the pathogen has in deed been eliminated from the herd.
