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.

Zoonotic Onchocerca in a Japanese Child

The American Journal of Tropical Medicine and Hygiene, 1989
A 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.

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.

Onchocerca gutturosa and Onchocerca lienalis in cattle: Variation in length of microfilariae by site of recovery

American Journal of Veterinary Research, 1989
SUMMARY Dermal microfilariae recovered from specimens obtained from umbilical and cervical sites of cattle infected with adult Onchocerca gutturosa alone or with adults of O gutturosa and O lienalis were measured and compared with uterine microfilariae obtained directly from gravid female worms of each species. Uterine microfilariae of O gutturosa were

Morphology ofOnchocerca volvulus

American Journal of Clinical Pathology, 1972
Onchocercal 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, 2009
Parasite-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.
