Cryopreservation of Infective Larvae of Onchocerca volvulus (Filarioidea: Onchocercidae)
The Journal of Parasitology, 1993Infective larvae (L3) of Onchocerca volvulus were procured in Liberia, West Africa, in the natural black fly vector, Simulium yahense. A cryobiological technique was developed to preserve L3 of O. volvulus that were fully viable after thawing. Larvae were treated before cooling with 4 cryoprotective compounds. Three compounds, dimethyl sulfoxide (DMSO),

Karyotypes of Brugia pahangi and Brugia malayi (Nematoda: Filarioidea)
The Journal of Parasitology, 1983Using air-dried preparations of the testis and ovary, karyotypes were analyzed and compared to each other in two species of filarial parasites, Brugia pahangi and B. malayi. Both species had a diploid number of 10 chromosomes and were karyotypically very similar.

Immunocytochemical and ultrastructural studies on Dipetalonema viteae (Filarioidea)
Journal of Helminthology, 1983ABSTRACTThe antigenic properties of adult male and female of Dipetalonema viteae were studied by immunocytochemistry. Using antisera of the rodents Meriones unguiculatus and Mastomys natalensis infected with D. viteae, the binding of antibodies to sections of filariae embedded in Epon was assayed by the peroxidase-antiperoxidase (PAP) technique and by ...

"Dipetalonema viteae" (Filarioidea) : development of the infective larvae in vitro
Acta tropica, 1981The development of Dipetalonema viteae third stage larvae was attempted in vitro. A monophasic culture system consisting of BHK-21 medium supplemented with 10% tryptose-phosphate broth and 15% fresh jird serum allowed the growth of previously in vivo triggered larvae, but not of those isolated from ticks. The larvae could complete their third moult and

THE PATHOLOGY OF Filaria taxideae (FILARIOIDEA: FILARIIDAE) INFECTION IN THE BADGER
Journal of Wildlife Diseases, 1971A description is given of the cutaneous lesions associated with Filaria taxideae Keppner, 1970 infections in badgers, Taxidea taxus (Schreber, 1778), from Wyoming. Female F. taxideae migrated into the dermis of the host and deposited their ova beneath the epidermis.

Immunocytochemical studies on Dipetalonema viteae (Filarioidea).
Tropenmedizin und Parasitologie, 1982The antigenic properties of adult male and female worms of the nematode Dipetalonema viteae (Filarioidea) were studied by immunocytochemistry. Using sera of rodents infected with this parasite, the binding of antibodies to sections of worms embedded in Epon was assayed by the peroxidase-antiperoxidase (PAP) technique and by light microscopy.

The comparative morphology of cephalic structures in the superfamily Filarioidea (Nematoda)
Canadian Journal of Zoology, 1968Cephalic structures in 62 genera of the nematode superfamily Filarioidea are compared. Vestiges of pseudolabia do not occur in filarioids and the persistence of internal cephalic papillae in some genera indicates that this superfamily branched off early from a stem which also gave rise to the Spiruroidea.

Onchocerca sweetae(Nematoda: Filarioidea): notes on the intermediate host
Journal of Helminthology, 1978ABSTRACTMicrofilariae ofOnchocerca sweetaeare broadly distributed in the superficial layers of the dermis of the water buffalo (Bubalus bubalis). A total of 2855 insects representing 20 species were collected fromO. sweetae-infected bait buffaloes. Only one species,Culicoidessp. “M”, ingested microfilariae from buffalo skin.

Scanning Electron Microscopy of Adult Wuchereria bancrofti (Nematoda: Filarioidea)
The Journal of Parasitology, 1995Despite the great importance of Wuchereria bancrofti in causing human lymphatic filariasis, only conventional morphological studies have been completed with adult forms of this filaria. No ultrastructural studies have been carried out, mainly due to the difficulty in obtaining viable parasites from human tissues and the lack of a suitable experimental ...

Ultrastructural analysis of Wuchereria bancrofti (Nematoda: Filarioidea) body wall
Micron, 2010Bancroftian filariasis constitutes the principal mosquito-borne nematode infection of humans and the surface of adult of Wuchereria bancrofti seems to be especially important in the intricate interplay between host and parasite. The study of the parasite's surface structure might help to understand the localization and function of various organelles. W.
