Microsporidia (Microspora: Microsporida) from Newfoundland blackflies (Diptera: Simuliidae)

Canadian Journal of Zoology, 1981
Examination of several hundred microsporidia-infected blackfly larvae collected in Newfoundland, Canada, revealed the presence of seven clearly distinguishable microsporidian species: Caudospora simulii, Caudospora polymorpha, Amblyospora bracteata, Thelohania varians, Thelohania fibrata, Tuzetia debaisieuxi, and Pleistophora multispora.

Two-Dimensional Electrophoretic Analysis of Spore Proteins of the Microsporida

The Journal of Parasitology, 1987
Microsporida are potentially useful as biological control agents for insects of economic and medical importance. Prior to their responsible use, however, an accurate and reliable means of identification to the species and subspecies level is required.

[Microsporida microsporidiosis].

Annales de biologie clinique, 1994
Microsporidia were infrequent in man until 1985. A new species, Enterocytozoon bieneusi, responsible for diarrhea, was described in AIDS patients in 1985. Little is known about the parasite; its diagnosis is difficult, and its incidence certainly underestimated.

New Family, Genus, and Species of Microsporida (Protozoa: Microsporida) from the Tropical Fire Ant, Solenopsis geminata (Fabricius) (Insecta: Formicidae)*

The Journal of Protozoology, 1978
SYNOPSIS. A new species of Microsporida, Burenella dimorpha sp. n., representing a new family, Burenellidae fam. n. and genus, is described on the basis of light‐ and electron‐microscope observations. The family is characterized by 2 sequences of sporogony, each sequence having morphologically different sporonts and spores.

Ecology of Simuliidae, Mermithidae, and Microsporida in Newfoundland freshwaters

Canadian Journal of Zoology, 1974
Prosimulium mixtum/fuscum S. &D., Cnephia mutata (Malloch), C. dacotensis D. &S., Simulium aureum Fries, and S. gouldingi Stone are univoltine. S. venustum Say, S. vittatum Zett., S. tuberosum (Lundstrom), S. corbis Twinn, S. latipes (Mg.), and S. decorum Walker are multivoltine.

Shell mats associated with microsporida in Biomphalaria glabrata: Genetic studies

Journal of Invertebrate Pathology, 1974
Abstract Multilayered mats have been observed lining the shell of some Biomphalaria glabrata infected with Steinhausia brachynema . Occurrence of the mats is associated with extensive infection with the microsporidia in these snails, in contrast to most B. glabrata in which infection appears restricted to the intestinal wall.

Mass production and storage of Vairimorpha necatrix (protozoa: Microsporida)

Journal of Invertebrate Pathology, 1979
Abstract Mass production and storage methods were evaluated for maximization of spores of Vairimorpha necatrix, a promising protozoan for microbial control due to its virulence and prolificity in lepidopterous pests. In vivo spore production was at a maximum when 3rd instar Heliothis zea were exposed to 6.6 spores/mm2 of artificial diet surface and ...

Ultrastructure of a Microsporidian Hyperparasite, Unikaryon legeri (Microsporida), of Trematode Larvae

The Journal of Parasitology, 1987
Unikaryon legeri (Dollfus, 1912) Canning and Nicholas, 1974, has been reexamined by electron microscopy from material collected in Portugal. It parasitises metacercariae of Meigymnophallus sp. in Cardium edule. A sporophorous vesicle forms around the sporonts, arising as a blister that separates from the electron-dense surface coat of the sporont ...

Nosema cuneatum sp. n. (Microsporida: Nosematidae) in grasshoppers (Orthoptera: Acrididae)

Journal of Invertebrate Pathology, 1971
Abstract Nosema cuneatum , sp. n., isolated from the grasshopper Melanoplus confusus , is characterized in fresh preparations by oval to cuneate spores averaging 4.8 μ long by 3.4 μ wide and by infections in the pericardium, fat body, gonads, tracheal matrix, midgut epithelium, Malpighian tubules, and neural tissues.
