Theileria microti

Theileria microti is a parasitic blood-borne piroplasm transmitted by deer ticks. It was previously in the taxonomic genus Babesia, as Babesia microti, until ribosomal RNA comparisons placed it in the sister genus Theileria. T. microti is responsible for the disease human theileriosis, similar to babesiosis, a malaria-like disease which also causes fever and hemolysis.
