The aim of this work is to summarize the results of laboratory studies of Ixodes ricinus ticks collected in recreational areas of Ternopil (Ukraine) and compare them with similar results of studies by a number of European researchers who studied ticks in suburban areas of large European cities, such as Warsaw, Prague, Bonn, Helsinki, etc. Ticks were collected using a "flag" (a 1m x 1m white cloth dragged across the grass), manually removed from plants and clothes of people walking in parks and finding these arthropods. The ticks were examined using real-time polymerase chain reaction (PCR) on the ROTOR Gene 6000 amplifier, which helped to determine the composition of pathogens that ticks can carry. The pathogens themselves were identified using several test systems, namely: "DNA A. phagocytophilum / DNA E. muris / DNA E. chaffeensis"; "DNA B. burgdorferi s. l."; "DNA B. myamotoi"; "DNA Babesia species"; "RNA Ticks borne of encephalitis viruses" (manufactured by MolGen (Italy)), which allow real-time detection on the ROTOR Gene 6000 amplifier. During 2017-2022, ticks were collected in parks and squares in Ternopil. They were examined in the laboratory of the Center for the Study of Ticks and Tick-Borne Infections of the Ternopil Gorbachevsky National Medical University using the real-time polymerase chain reaction (PCR) on the ROTOR Gene 6000 amplifier. From 2017 to 2022, 881 ticks were subjected to PCR testing. It was found that 257 individuals, or 29.17% of the total number of ticks tested, were carriers of infectious diseases, of which 117 specimens, or 13.28%, were carriers of B. burgdorferi sl., B. miyamotoi - 5 specimens, or 0.57%, A. phagocytophilum - 97 specimens, or 11.01%. Among the infected ticks there were carriers of 2 pathogens simultaneously. In particular, 32 individuals were vectors of B. burgdorferi + A. phagocytophilum, which amounted to 3.63%, B. burgdorferi sl. + B. miyamotoi - 3 specimens, or 0.34%, B. miyamotoi + A. phagocytophilum - 2 specimens, which corresponded to 0.23%. We also found 1 tick carrying three pathogens simultaneously: B. burgdorferi + B. miyamotoi + A. phagocytophilum. The analysis of the results obtained regarding the distribution of pathogens of the B. burgdorferi sl. in ticks collected within the city of Ternopil showed that our results practically correlate with the results of European researchers. The percentage of infected ticks in our results ranged from 13.28 % (minimum 7.69 % and maximum 33.33 %), and in some European cities it ranged from 13.2 - 38.5 % in Prague to 19-55 % in Helsinki, with intermediate results in Olsztyn (Poland) - 27.4 %, in Bratislava - 13.2 %, in Switzerland - 18 % (average of 18 large cities). These figures largely depended on the stages of tick development and environmental conditions in different years.
