Enterocytozoon bieneusi is the most common microsporidian parasite in human patients with acquired immunodeficiency syndrome (AIDS), and since its recognition in 1985, it has been associated with a severe enteropathy and biliary cirrhosis in these patients.[1-3] Microsporidia are obligate intracellular parasites that lack mitochondria and use a unique polar tube apparatus to infect the host cell.[4,5] Despite its common occurrence, basic aspects of parasite biology and host immunity are poorly understood.
