Nosema acridophagus in the fat body of the grasshopperMelanoplus sanguinipes was investigated by electron microscopy. The stages observed were diplocaryotic throughout most of the life cycle and developed in direct contact with the host cytoplasm. The meront plasmalemma was covered by a layer of tubular elements that transversely encircled the parasite. These tubular elements were not evident when a homogeneous electron-dense exospore layer was deposited on the meront plasmalemma surface…

Tubulinosema loxostegi sp.n. (Microsporidia: Tubulinosematidae) from the beet webworm Loxostege sticticalis L. (Lepidoptera: Crambidae) in Western Siberia

Spore ultrastructure is characteristic of the genus Tubulinosema, and Sequencing of small subunit and large subunit ribosomal RNA genes showed 98–99.6% similarity of this parasite to the TubulinOSEma species available on Genbank.

An Ultrastructural Study of Nosema locustae Canning (Microsporidia) from Three Species of Acrididae (Orthoptera)

The study did not reveal any difference in the morphology of N. locustae while developing in the three different hosts, which is typical for microsporidians of the genus Nosema.

Transfer of Nosema locustae (Microsporidia) to Antonospora locustae n. comb. Based on Molecular and Ultrastructural Data1

The ultrastructure of mature N. locustae spores is examined, and it is found the spore wall to differ from true Nosema species in having a multi-layered exospore resembling that of Antonospora (one of the distinguishing features of that genus).

Specified Ultrastructural Data on Tubulinosema maroccanus Comb. Nov. (Nosema maroccanus Krilova et Nurzhanov, 1987) (Microsporidia) from the Moroccan Locust Dociostaurus maroccanus (Orthoptera)

Analysis of cell surface ultrastructure of two Tubulinosema species from Orthoptera showed that they shared two characters not mentioned in the diagnosis of the genus, which were modified to include presence of vesicles with electron-dense cores surrounding sporogonial stages and presence of microtubuli not only in late meronts, but also in some species, in spores.

Systenostrema alba Larsson 1988 (Microsporidia, Thelohaniidae) in the Dragonfly Aeshna viridis (Odonata, Aeshnidae) from South Siberia: Morphology and Molecular Characterization

Based on ultrastructural similarity, this Siberian isolate is considered to be Systenostrema alba, a species described from Aeshna grandis collected in Sweden and maximum likelihood, neighbor joining, and maximum parsimony analyses of the small subunit rDNA all placed it as the sister taxon to a clade consisting of Thelohania solenopsae, Tubulinosema ratisbonensis, and Tubulinosity acridophagus.

Morphological and Molecular Investigations of Tubulinosema ratisbonensis gen. nov., sp. nov. (Microsporidia: Tubulinosematidae fam. nov.), a Parasite Infecting a Laboratory Colony of Drosophila melanogaster (Diptera: Drosophilidae)

A new species of microsporidia from Drosophila melanogaster was investigated by light and electron microscopy and by ribosomal RNA (rRNA) sequencing and transferred to the new genus Tubulinosema gen. nov.

Development, ultrastructure, natural occurrence, and molecular characterization of Liebermania patagonica n. g., n. sp., a microsporidian parasite ot the grasshopper Tristira magellanica (Orthoptera: Tristiridae).

Fitness effects and transmission routes of a microsporidian parasite infecting Drosophila and its parasitoids

In Drosophila, infections caused changes in most of the traits that were associated with fitness, in particular causing a 34–55% reduction in early-life fecundity, and the potential importance of Microsporidia in parasitoid-host interactions is discussed.

Classification and Phylogeny of the Microsporidia

The classification of the microsporidia has undergone many changes since the first simple system was proposed by Thelohan in 1892. This has been necessary because each new system or each modification…

Systematics of the Microsporidia

The phylogeny of the Microsporidia is unknown, but it is likely that the structure of the cells is similar to that of “spatially aggregatingopolypeptide”, a type ofopolymer.
