Between 1995 and 1997, at the beginning of an epizootic called “maladie de l’amagrissement du porcelet” (MAP), it was observed that the farms that were most affected and that had the most losses, generally presented obvious deviations from what we would consider to be a suitable management of the animals and facilities. This is why Dr. François Madec made a list of management practices with the aim of improving the anomalous situation observed.

There are several decisions to make before attempting an eradication programme. Firstly, which antibiotic should we use? If we have had the disease on the farm for some time, the Brachyspira will have been exposed to possibly a number of drugs and may have reduced susceptibility to some of them.

The use of diagnostics will allow producers and practitioners to work together towards the common goal of PRRS eradication

On December, the Philippine Department of Agriculture announced that the non-lethal Ebola Reston Virus previously only found in monkeys, had been detected in pigs

The first swine influenza viruses were all H1N1 and were for about 60 years in North America. In the middle 1980’s, there appeared in European pigs H3N2 viruses that were derived originally from humans and had adapted to pigs and were therefore known as human-like H3N2 viruses. These viruses have since appeared in other parts of the world most notably as H3N2 in the USA in 1998. These viruses however contained bits of human, avian and swine viruses and were therefore called triple re-assortants.

It is produced by a virus with genetic material from porcine, human and avian viruses which has shown the ability unusually for such a virus to transmit from human to human. The virus appears to have 2 of 8 gene segments that derive from eurasian swine viruses. The NA and matrix genes of the new virus have not been seen in humans or pigs before.

Preventing vertical and horizontal spread of PRRSV from dam to offspring is critical for the production of naive replacement stock

The aim of this article is to discuss those differentiating topics which are relevant from a practical point of view and which in some way elude the disease's definition.

This is the first of a series of articles written by Tom Alexander for www.3tres3.com which we would like to publish again here as a way of paying homage and showing gratitude for his invaluable collaboration.

Trailers contaminated with PRRSV can serve as a source of infection for naïve pigs. Therefore, sanitation for livestock trailers and transport vehicles is considered a high priority when it comes to biosecurity practices.

The autopsy is always an important diagnostic element for the majority of diseases, and this is the same for porcine circovirosis.

Control of PCV2 infections are increasingly through piglet vaccination now that global supplies are increasing.

The presence of subpopulations of exposed and non-exposed sows in chronically PRRSV-infected breeding herds assists in the maintenance of virus circulation in the breeding herd over time.

Porcine circovirus type 2 (PCV2) infections can be extremely costly causing wasting and increases in mortality.
