Abstract: Emergence of new virus variants and new diseases in poultry leads to growth of the number of infections for which vaccination is required. In the current situation, scientific approach to diagnostic tests and preventive measures, based on knowledge of epizootology, biological properties of pathogens, immunology patterns as well as classical and new methods of research is especially important.
