Summary: The results of the monitoring the child with contamination of tick bite during the spring-autumn of 2018 in Ternopil and Ternopil region were summarized, according to which the peak of such lesions occurred in May-June and August-September. It was found that the percentage of ticks infected with pathogens of infectious diseases, namely Borrelia burgdorferi s.l., Borrelia miyamotoi and Anaplasma phagocytophilum, was about 37%. There were cases where the ticks were infected with multiple pathogens (B. burgdorferi s.l. with A. Phagocytophilum, B. miyamotoi and A. rhagocytophilum) simultaneously. Regarding the importance of different stages of the tick Ixodes ricinus in the transmission of infectious agents, it has been shown that a greater number of vaccinated individuals were among females and nymphs. Although the role of males and larvae in this process can not be ruled out either. There were 47 females, 76 nymphs, 1 male and 4 larvae among 128 infectes ticks.
