The ultrastructure of three microsporidia from winter moth, Operophtera brumata (L.), and the establishment of a new genus Cystosporogenes n.g. for Pleistophora operophterae (Canning, 1960)

Morphology and taxonomy of the microsporidium Liebermannia covasacrae n. sp. from the grasshopper Covasacris pallidinota (Orthoptera, Acrididae)

“…Interestingly, this species as well as its congener O. operopthterae, the parasite of salivary glands of the winter moth Operophtera brumata, are closely related to Liebermannia spp. based on structural characters (Andreadis et al, 1996;Canning et al, 1985) and SSU rDNA sequence divergence (Table 2). It is noteworthy that none of the midgut parasites exhibited meiosis; most of them are monokaryotic throughout the life cycle, and only Hessea squamata and Nosema spp.…”

Ultrastructural study on a novel microsporidian, Endoreticulatus eriocheir sp. nov. (Microsporidia, Encephalitozoonidae), parasite of Chinese mitten crab, Eriocheir sinensis (Crustacea, Decapoda)

“…Although in many papers, the origin of the wall has not been clearly observed and stated (Lom and Nilsen, 2003). Canning et al (1985) studied Cystosporogenes operophterae and found that spores were produced in groups within a Wne, semi-persistent envelope but were unable to determine whether the envelope was a SV or a PV of host origin. In the case of Endoreticulatus Wdelis, the vacuole was bound by two membranes and, by virtue of the ribosome studding on the outer of the two membranes, the vacuole was identiWed as being of host origin, derived from the endoplasmic reticulum (Brooks et al, 1988).…”
