I. Christova et al., High prevalence of granulocytic Ehrlichiae and Borrelia burgdorferi sensu lato in Ixodes ricinus ticks from Bulgaria, J CLIN MICR, 39(11), 2001, pp. 4172-4174
Bulgarian Ixodes ricinus ticks were examined for Ehrlichia and Borrelia coi
nfection: 34 and 32% of adult ticks and at least 2 and 10% of nymphs were p
ositive for these infections, respectively. Coinfections and dual or triple
Borrelia infections were frequent, although Ehrlichia phagocytophila heter
ogeneity was minimal. Multiple tick-borne bacteria coexist in I. ricinus ti
cks in southeastern Europe.
