Encephalitozoon intestinalis microsporidiosis was thus shown in two of the four patients examined. In two patients, therapy based on albendazole made stools. Encephalitozoon intestinalis is transmitted in contaminated water and initially infects gastro-intestinal enterocytes, leading to diarrheal disease. Encephalitozoon intestinalis is a recently described microsporidian which causes intestinal and disseminated infections in severely immunocompromised.

Scanning electron micrograph of a microsporidian spore with an extruded polar tubule inserted into a eukaryotic cell. Microsporidiosis in the immunocompromised first became evident during the Acquired Immunodeficiency Syndrome AIDS pandemic, but remains a concern in Human Immunodeficiency Virus HIV -infected individuals without access to therapy, as well as those immunosuppressed due to cancer therapy, diabetes, organ transplants, and autoimmune disease [ 1 ].

Either free in the cytoplasm or inside a parasitophorous vacuole, microsporidia develop by sporogony to mature spores. Unidentified microsporidia stained with Chromotrope 2R. Microsporidia infection also inhibits lntestinalis, caspase 3-mediated apoptosis [ 12 ] – an important mechanism by which some viruses promote host cellular transformation.
