Summary. Intestinal yersiniosis is a dangerous infectious disease of farm animals caused by Yersinia enterocolitica. In young animals the disease occurs with symptoms of gastro-intestinal tract lesions. The subclinical form of the disease is detected in adult animals. Infected animals remain agents during the whole period of the life and there are a threat for livestock and human health. Such animals are identified by serological studies. Nowadays the research on the distribution of intestinal yersiniosis in Ukraine has been conducted insufficiently. The results of the conducted serological screening of intestinal yersiniosis causative agent of Yersinia enterocolitica serovar O:9 on the animal-breeding farms of the different regions of Ukraine. Serological screening was done on the 15 farms in 7 regions of Ukraine, 213 blood serum samples from cattle, sheep, pigs were examined.
