Infectious rhinitis is a respiratory bacterial disease in poultry that can lead to significant economic losses. The article provides an analysis of literature data on the current epizootic situation on infectious rhinitis in different countries of the world, an analysis of the economic losses that may be caused by the appearance of this pathogen in the poultry farm. For today in Ukraine, the situation for haemophilus infection in poultry is unknown. It is not included to the list of particularly dangerous infectious diseases and therefore infection cases officially are not reported. But this issue exists in poultry farms of Ukraine and therefore, the main goal of our work was to study the occurrence of haemophilus causative agent in poultry farms of different age, with different types of production and in various regions of Ukraine. As the results of PCR studies conducted in 2015-2018, haemophilus causative agent was detected in 8 out of 18 studied farms. Pathogen's circulation was detected in poultry farms in 8 oblasts of Ukraine in Western, Eastern, Central and Southern regions. Herewith, the pathogen was detected both in layer hens, in broilers and in broiler parent flock. The pathogen was detected in Ukraine in poultry of different age groups. The presence of this pathogen in pathological/clinical material was 20-100 %, on average, this index varied 28,28-64,51%. Identification of pathogen in Ukraine testifies to the relevance of this disease for our country, as well as the need for in-depth study of the pathogen, improvement of laboratory diagnostics and specific prevention.
