Our Meeting will be held at the famous Jagiellonian University in Kraków, in a sig- nificant academic and cultural centre of Poland. We promise to do our best to make your stay in Kraków, the old Polish capital, the royal city full of charm of contempo- raneity as well as the world-famous monuments, the most unforgettable scientific and social experience. Let me introduce you to the 27th Meeting of the European Society of Veterinary Pa- thology and the European College of Veterinary Pathologists. Traditionally, ESVP Congresses are held every year. This Meeting in Kraków will be the first officially joint congress of the ESVP and the European College of Veterinary Pathologists. More over, it will take place together with meetings of the International Society of Veterinary Dermatopathology, C.L. Davis Foundation – European Division and the Polish Small Animal Veterinary Association, Oncology Section. Consequently, the 27th Meeting of ESVP and ECVP will offer an unique platform for exchange of infor- mation and experience as well as presentation and discussions of the latest achieve- 7 ments in our research. It should enhance international scientific cooperation and enable us to elaborate applications for daily practice. It will provide a comprehensive update of the state-of-the-art in all relevant disciplines contributing to pathomorpho- logy, morphology and clinical pathology. Plenary lectures (6) and parallel 16 sessions with 44 oral presentations and 154 poster presentations will cover the subjects of histopathology, ultrastructural pathology, molecular pathology, toxicological patho- logy, experimental pathology, techniques in pathology and morphological sciences, clinical pathology and toxicological clinical pathology. The programme also includes a Mystery Slide Session on Dermatopathology and Workshop on Fish Pathology. The organizers of the Meeting would like to thank all those who have contri buted to the organization of these events in Kraków, particularly to the International Educational Board and boards of the European Society of Veterinary Pathology, European College of Veterinary Pathologists, International Society of Veterinary Dermatopathology, Polish Society of Pathologists and Polish Small Animal Veteri- nary Association. We are also grateful to all our sponsors and trade exhibitors for their help. We also thank all Delegates for coming to Kraków and for taking part in the creation of these events. We believe that the 27th Meeting of ESVP and ECVP will have the same high stan- dard as those of previous years and that they will be “good harvest of the research field” and also provide you with an opportunity to stimulate your own investiga- tions. We wish you a pleasant and fruitful stay in Kraków. Prof. Dr hab.

Segalés Joaquim Research Centre on Animal Health (CReSA), Foundation UAB-IRTA, Faculty of Veterinary Medicine, Autonomous University of Barcelona, 08193 Bellaterra, Barcelona, Spain e-mail: [email protected] Introduction Looking at the literature, there are many definitions of emerging infectious diseases. As an example, they have been defined as these whose incidence have increased in the past 20 years and threaten to increase in the near future. The natural history of new infec- tions is rather simple from a generic point of view (fig. 1). However, even controlling the disease/infection is very difficult per se, to live with an enzootic scenario could be worse than to eradicate it and being threatened by the risk of re-infection. Such situ- ation is especially important when dealing with livestock diseases/infections since the loss of production or competitiveness may cause significant economic disadvantages, not only for the producers but also for a country or region as a whole.
