Natural Focality of Lyme Borreliosis, Granulocytic Anaplasmosis, and Monocytic Ehrlichiosis in Humans in the Republic of Tatarstan

Objective of the study is to investigate natural focality of Ixodidae tick borreliosis, granulocytic anaplasmosis, monocytic ehrli-chiosis in humans in the Republic of Tatarstan. Materials and methods. Utilized were the data from tick studies conducted between 2010–2015. Applying immune-enzymatic analysis, investigated were the blood sera from residents (donors) of Kazan and municipal districts of the Republic of Tatarstan for the presence of specific antibodies to borreliosis, ehrlichiosis, and anaplasmosis pathogens. Results and conclusions. For the first time ever, the data on spontaneous carriage of Ehrlichiosis pathogens in Ixodidae ticks have been obtained.
