The phylum Apicomplexa comprises intracellular protozoa that include many human pathogens. Their nearest relatives are chromerids and colpodellids. We report a case of a Babesia spp.-like relapsing infection caused by a newly described microorganism related to the Apicomplexa. This case is highly suggestive of a previously undescribed type of colpodellid that infects vertebrates. The phylum Apicomplexa comprises intracellular protozoa that include human pathogens that cause diseases such as babesiosis, malaria, and toxoplasmosis (1). Apicomplexa evolved from algal ancestors, and their nearest relatives are algae (chromerids) and predatory flagellates (colpodellids) (2,3). We report a case of relapsing infection that has many characteristics in common with babesiosis. Amplification of DNA in blood and molecular phylogenetic characterization revealed a novel nucleotide sequence closely related to Colpodella and Chromera spp. [ABSTRACT FROM AUTHOR]
