<i>Babesia microti</i>—<i>Borrelia burgdorferi</i> Coinfection

Abstract

The incidence and geographic distribution of human babesiosis is growing in the U.S. Its major causative agent is the protozoan parasite, Babesia microti. B. microti is transmitted to humans primarily through the bite of Ixodes scapularis ticks, which are vectors for a number of other pathogens. Other routes of B. microti transmission are blood transfusion and in rare cases of mother-to-foetus transmission, through the placenta. This review discusses the current literature on mammalian coinfection with B. microti and Borrelia burgdorferi, the causative agent Lyme disease.
