Molecular Characterization of Human Pathogen Babesia EU1 in Ixodes ricinus Ticks From Slovenia

Abstract
New cases of human babesiosis were recently reported in Europe. The etiological agent was identified as Babesia EU1, a zoonotic pathogen with previously unreported molecular characteristics. On the basis of a comparison of the complete babesial 18S rRNA gene, we have generated strong molecular evidence that Ixodes ricinus ticks from Slovenia are infected with EU1.
