Epidemiological Manifestations Ixodid Tick-Borne Borreliosies in Irkutsk and in other Parts of the Eurasian Area
Background. Ixodid tick-borne borrelioses (ITBB) is the most prevalent in Northern Hemisphere group of transmissible Spirochaetal infections, ecologically connected with Ixodid ticks. ITBB are etiologically associated with several agents, which determine epidemiological and clinical manifestations o...
