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

Abstract

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. The information received is an indicative of the active circulation of Borrelia, Ehrlichia and Anaplasma in the territory of the region and of necessity to expand the research on the “novel” for the Republic nosological forms of natural-focal infections.
