Electron microscope and time lapse, phase contrast cinematography studies on Babesia equi organisms within equine red blood cells revealed that this hemoprotozoon has two organelles possibly involved with ingestion of nutrients: a cytostome that takes in hemoglobin from the host cell and a tubule that extends from the main body of the parasite through the erythrocyte to the blood plasma and appears to ingest plasma during periods of rapid growth and development.
