Pigs that are not affected by the disease tend to have a quantity of sero-neutralizing (and also total) antibodies against PCV2, which is significantly greater than those that cause disease

Joaquim Segalés i Coma was born in Vic (Barcelona) in 1968, he graduated at the Veterinary Faculty of the Universitat Autónoma de Barcelona (UAB) in 1991. He then received a doctorate in Veterinary Science in 1996 at the same university after having spent 15 months at the University of Minnesota (UM) in the USA, under the codirectorship of Dr. Mariano Domingo (UAB) and Dr. Carlos Pijoan (UM). In 2000 he achieved a diploma at the European College of Veterinary Pathology (ECVP). In year 2004 he graduated at the European College of Porcine Health and Management (ECPHM), of which he is a founding member and its current vice-president. He currently works as professor at the Department of Animal Anatomy and Welfare at the Veterinary Faculty of the UAB, where he teaches in the area of pathologic anatomy and porcine clinic. He is also the Director of the Centre de Recerca en Sanitat Animal (CReSA).
Dr. Segalés has taken part in numerous research projects, at both a national and a European level. He is especially skilled in different porcine diseases and has collaboration agreements with different enterprises, both national and European, that are involved in the sector. Of the many lines of research that he has participated in, the most important are the Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), Haemophilus parasuis, the Aujeszky Disease Virus (ADV), the Hepatitis E Virus (HEV), torque teno sus virus and diseases associated with Porcine Circovirus type 2 (PCV2). It is also worth mentioning that Dr. Segalés participated in the first identification in Spain of the Post-weaning Multi-System Wasting Syndrome or Porcine Circovirus in 1997 and of the Porcine Dermatitis and Nephropathy Syndrome in 1996. As a result of these investigations he is the co-author of more than 200 articles published in international scientific journals, as well as being co-author of ten chapters of books with international prestige of which perhaps the most important is Porcine circovirus diseases in the 9th and 10th edition of the book Diseases of Swine. He is also the co-author of a book on swine livestock necropsy as well as three books on clinical cases in swine.

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.
The autopsy is always an important diagnostic element for the majority of diseases, and this is the same for porcine circovirosis.
It is assumed that the most probable route of PCV2 transmission is the oronasal tract, which would indicate that horizontal transmission (sow-piglet or piglet-piglet) is a frequent or very frequent occurence
Porcine circovirus type 2 is a viral agent with a relatively simple structural organization of which there are two distinct genotypes (1 and 2), it is not clear if they have similar virulence. Since some years ago there has been a hypothesis developing that there exists an “agent X” that would play a role as a trigger factor of the disease in 100% of cases.
Joaquim Segalés, professor at the Universitat Autònoma de Barcelona and researcher at the Centre de Recerca en Sanitat Animal (CReSA) (research centre for animal health), was one of the first researchers to discover PMWS and PDNS in Spain. He will be in charge of this section where every month articles will be published on the latest themes, especially from a practical point of view. These themes will include etiology, patogenicity, epidemiology, diagnostic, treatment and prevention of porcine circovirus-associated diseases. A possible hypothesis will also be presented on the emergence of porcine circovirus on a worldwide level.
