In Vitro Cultivation and Development of Onchocerca volvulus and Onchocerca lienalis Microfilariae
The American Journal of Tropical Medicine and Hygiene, 1996Onchocerca 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.

The actin genes of Onchocerca volvulus
Molecular and Biochemical Parasitology, 1992The 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.

Zoonotic Onchocerca in a Japanese Child
The American Journal of Tropical Medicine and Hygiene, 1989A female Onchocerca was found in histopathological sections of a nodule removed from the foot of a 2-year-old girl in southern Japan. As in previously reported cases in Switzerland, Crimea, Canada, and the USA, evident morphological features of the worm resembled those of Onchocerca gutturosa and O.

Intracytoplasmic Bacteria in Onchocerca Volvulus
The American Journal of Tropical Medicine and Hygiene, 1977Ultrastructural 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.

Surface components of Onchocerca volvulus
Molecular and Biochemical Parasitology, 1986A 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.

Purification of Onchocerca gibsoni microfilariae
International Journal for Parasitology, 1982Abstract 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 ...

Morphology ofOnchocerca volvulus
American Journal of Clinical Pathology, 1972Onchocercal nodules from 18 Africans were studied. Each nodule contained adult worms of Onchocerca volvulus . Male and female worms were reconstructed from serial paraffin sections, and the morphologic features of the adult worms and microfilariae described.

Onchocerca-Simulium interactions and the population and evolutionary biology of Onchocerca volvulus.
Advances in parasitology, 2009Parasite-vector interactions shape the population dynamics of vector-borne infections and contribute to observed epidemiological patterns. Also, parasites and their vectors may co-evolve, giving rise to locally adapted combinations or complexes with the potential to stabilise the infection.
