Summary
A microsporidian parasite is reported for the first time in Turbanella lutheri (Gastrotricha: Macrodasyida), a representative of a new
host class. Sporonts, sporoblasts, and spores located in host-derived vacuoles within the intestine cells are documented by TEM
micrographs. Mature spores, shells of hatched spores, and everted polar tubes occur also in the gut lumen of the host.
Key words: Microsporidia, new host, Gastrotricha, electron microscopy
