A general scheme of circulation of ixodid tick-borne borrelioses pathogens in the natural foci of Eurasia

Resumo

A quantitative scheme of the circulation of pathogens of ixodid tick-borne borrelioses is proposed, which may serve as the basis for further computer modeling of the epizootic process. The scheme is based on the general features of the multiyear development cycle of Ixodes persulcatus Shulze, 1930 and I. ricinus L., 1758, which are the main vectors and hosts of borreliae in Eurasia, and on the generalized parameters of their vertical and horizontal transmission.
