The authors give an overview about the important diagnostic and research results in Hungary from the 60's until today, relating to infectious (mainly viral and bacterial) goose diseases. Beside the previously known diseases of high economical impact (e.g. fowl cholera, salmonellosis, borreliosis, amidostomosis), at the beginning of the 60's exudative septicaemia, and later the so-called goose influenza, due to the high losses, threatened the future of the Hungarian goose breeding, which was extremely important economically even that time, because of goose liver and feather export. Clearing the ethiology of the disease (parvovirus) meant the success of Hungarian poultry health specialists, the result of which was that - based on international agreement - the disease is known as Derzsy's disease all around the world. During the development of efficient control, injection with serum, development of vaccine by attenuation of the virus, and later the production of recombinant subunit vaccine meant the most important milestones. The description in Hungary of Erysipelothrix rhusiopathiae septicaemia, anatipestiferinfection, reticuloendotheliosis, streptococcosis, Clostridium septicum caused septicaemia, and infectious cloacitis and penis inflammation assisted the knowledge about the new goose diseases. Around the turn of millenary and later the importance of waterfowls increased in poultry breeding in Hungary, and their proportion in the sample materials of veterinary institutes achieved and even exceeded that of domestic fowls. Parallelly, beside Derzsy's disease driven gradually back because of efficient control, new viral diseases (reovirus caused tenosynovitis, EDS-virus caused tracheobronchitis, Polyomavirus caused nephritisenteritis, circovirus caused bursal damage and immunosuppression, adenovirus caused hepatitis-hydropericardium or West Nile fever with encephalitis) occurred. Form of Derzsy's disease with enteral signs and lesions in the majority of cases (parvovirusenteritis of goslings) became common and intestinal spirochaetosis (brachyspirosis) of breeding geese, as well. In the avian influenza epidemic in 2006 Far-East water-fowl pathogenic H5N1 subtype virus strain caused losses in Hungary mainly in goose and duck flocks. Pathomorphological examination of the disease and serotropism studies of the virus strain proved neurotropic characteristic of H5N1 virus.
