Sažetak
Many challenges are facing the poultry industry, and viral infections are of a particular concern. Viruses can spread rapidly, they are not sensitive to antibiotics and cause devastating economic losses in poultry industries worldwide. Common markets and presence of international poultry companies provide for easier and faster spread of poultry viral infections to different countries, regions and even continents. In addition, recent spillovers of certain poultry-derived viruses into migratory bird populations have resulted in unpredictable outbreaks in remote poultry operations. The most important viral diseases representing major challenges to the poultry industry today are discussed here. None of such viral infections have been controlled to a satisfying extent at the global level so far, on the contrary more pathogenic or antigenic variant strains are increasingly emerging. Vaccination is possible for many viral infections of poultry, but it does not always warrant required protection. Undoubtedly, proper use of poultry vaccines through suitable vaccination programs has a precious impact on controlling and preventing viral infections and therefore in reducing economic losses. Nevertheless, poorly planned and/or improperly performed vaccinations can promote the emergence and enhance the transmission of virulent pathogens. Another issue is that vaccination cannot be a substitute for biosecurity and hygiene management, although there are such misconceptions. High competitiveness and demands for lower poultry production costs have altered the management system resulting in lowered emphasis in biosecurity and other basic disease control practices. Therefore, it can be concluded that management systems in poultry production that neglect fundamental disease control and eradication principles are in a great proportion responsible for emergence and spread of viral infections nowadays. All this makes viral infections of poultry a globally challenging situation and requires inclusion of specialized poultry veterinarians in disease consideration and decision making bodies already at the stage of planning new poultry operations.
