High Prevalence of Granulocytic Ehrlichiae and Borrelia burgdorferi Sensu Lato in Ixodes ricinus Ticks from Bulgaria

摘要

Bulgarian Ixodes ricinus ticks were examined forEhrlichia and Borrelia coinfection: 34 and 32% of adult ticks and at least 2 and 10% of nymphs were positive for these infections, respectively. Coinfections and dual or tripleBorrelia infections were frequent, although Ehrlichia phagocytophila heterogeneity was minimal. Multiple tick-borne bacteria coexist in I. ricinus ticks in southeastern Europe.
