Name

Greek: enteron = intestine; kytos = cell; zoon = animal; Bieneus = family of the first patient (♀) detected.

Geographic Distribution/Epidemiology

Worldwide; the first description occurred in France on material from a female Haitian patient. E. bieneusi represents about 40 % of all human infections due to microsporidia. About 10 % of the AIDS patients are infected in general with microsporidia in addition to other opportunistic agents of disease. E. bieneusi mainly infects AIDS patients.

Morphology/Life Cycle

Characteristic and name-giving for the microsporidia is the tiny sized spore, which is the infectious stage. Their life cycle derives in the same phases as diagrammatically described in Fig. 1 of Encephalitozoon cuniculi. The ovoid spores are ovoid, measure 1.5 × 0.5 μm. They possess a five times wound polar tube and their endospore is rather thin. In case such a spore is orally ingested within contaminated food or drinking water, inside the intestine the hollow tube is...
