The genomes of Onchocerca volvulus

International Journal for Parasitology, 2000
Onchocerca volvulus, the filarial parasite that causes onchocerciasis or river blindness, contains three distinct genomes. These include the nuclear genome, the mitochondrial genome and the genome of an intracellular endosymbiont of the genus Wolbachia.

Surface components of Onchocerca volvulus

Molecular and Biochemical Parasitology, 1986
A technique employing Sephadex G25 gel filtration has been developed for the rapid isolation and purification of live microfilariae of Onchocerca volvulus from subcutaneous nodules and skin samples. Microfilariae, adult worms and L3 larvae have been surface radiolabelled using the Iodogen technique.

Intracytoplasmic Bacteria in Onchocerca Volvulus

The American Journal of Tropical Medicine and Hygiene, 1977
Ultrastructural studies on Onchocerca volvulus disclosed intracellular organisms within the lateral chords of adult worms and of the larval stages. In the females the organisms were also present in the oogonia, oocytes, developing eggs and microfilariae.

Purification of Onchocerca gibsoni microfilariae

International Journal for Parasitology, 1982
Abstract Forsyth K. P. , Copeman D. B. and Mitchell G. F. 1982. Purification of Onchocerca gibsoni microfilariae. International Journal for Parasitology 12 : 53–57. Viable microfilariae from the bovine parasite, Onchocerca gibsoni , were purified to a level suitable for immunochemical analysis and without appreciable loss in numbers by low ...

In Vitro Cultivation and Development of Onchocerca volvulus and Onchocerca lienalis Microfilariae

The American Journal of Tropical Medicine and Hygiene, 1996
Onchocerca volvulus and O. lienalis skin-derived microfilariae (mf) were cultured in vitro; parasite viability was assessed at intervals by measuring their ability to develop in Simulium ornatum. In the presence of monkey kidney feeder cells, both species retained full viability when cultured for up to 5 hr before intrathoracic injection into Simulium.

Identification of antigens of Onchocerca volvulus and Onchocerca gibsoni for diagnostic use

Molecular and Biochemical Parasitology, 1986
Adults of Onchocerca volvulus and Onchocerca gibsoni were identically fractionated into a surface-enriched fraction, a phosphate buffered saline (PBS) extract and a PBS insoluble-detergent soluble fraction. Glycoproteins were prepared from these extracts and all fractions were examined by the Western blot technique using sera from individuals infected ...

"Onchocerca cervicalis" in horses : dermal histopathology

Acta tropica, 1985
A histopathological study of ventral midline skin from midwestern U.S. horses with and without onchocerciasis due to Onchocerca cervicalis found perivascular mononuclear dermatitis as the most consistent difference between the two groups. Seasonal variation in parasite numbers or cellular influxes was not observed.

The actin genes of Onchocerca volvulus

Molecular and Biochemical Parasitology, 1992
The genome of Onchocerca volvulus was found to contain 2 actin gene classes (called 1 and 2) of 2 genes each. The 4 genes are located in 2 clusters (called A and B), each containing a gene class member. Five short introns of 122-207 bp occur within each gene.
