Purpose: to study the distribution of nutrients and the frequency of detection of DNA / RNA of tick-borne pathogens in ticks selected from animals and from the environment of some regions of Ukraine.
Materials and Methods. A “flag” was used to extract ticks from the environment, and tweezers were used to remove them from the body of animals. The ROTOR Gene-6000 amplifier, 5-channel (Corbett Research, Australia), was used for PCR research.
Results. According to the results in period from May to November 2021, 128 ticks were caught in the environment, including 26 ticks Ixodes ricinus, which is 20.3 % of the total number of captured ticks, and 102 ticks Dermacentor reticulatus, which is 79.7 %.
The geography of tick catches covered 7 regions: Ternopil, Lviv, Volyn, Rivne, Khmelnytsky, Vinnytsia, Zhytomyr.
Among the mites of the species Ixodes ricinus that were removed from animals, 69.2 % are mites found on cats, 30.8 % of mites were collected “on the flag” from the environment. Ixodes ricinus mites have not been identified in dogs and cows. Ticks of the species Dermacentor reticulatus were obtained from the following animals: from cows – in 62.8 % of cases, from dogs – in 27.2 % of cases.
Carriers of infectious agents were detected in 34 cases, which is 91.2 % of the total number of mites tested by PCR.
Conclusions. Ticks of the species I. ricinus were most often extracted from the environment on the “flag” and found on cats and they were carriers of A. phagocytophilum and, much less frequently – Babesia cf. and tick-borne encephalitis virus, while D. reticulatus ticks were most common in larger animals: cows, dogs and were infected with tick-borne encephalitis virus and Babesia cf.
