Chitin in egg shells of Onchocerca gibsoni and Onchocerca volvulus

Molecular and Biochemical Parasitology, 1987
Chemical analysis of adult females of Onchocerca gibsoni gave estimated chitin contents of 200-500 micrograms (g dry weight)-1. Egg shells from both O. gibsoni and Onchocerca volvulus stained with Calcofluor white and with fluorescent wheat germ agglutinin as shown by fluorescent light microscopy, and bound gold-labelled wheat germ agglutinin as shown ...

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.

Extracellular proteases of Onchocerca

Experimental Parasitology, 1989
Two important events in infection by Onchocerca parasites involve cutaneous tissue migration by larval stages. L3 larvae migrate from the blackfly bite site to subcutaneous locations for adult development, and microfilariae from subcutaneous nodules to distant regions of the skin and sometimes the eye.

Antigens of Onchocerca volvulus

Clinical Infectious Diseases, 1985
Most studies on immunologic responses to Onchocerca volvulus have employed extracts or antigens from related filarial parasites. Consequently, little is known about the nature of O. volvulus antigens. Potential antigen sources include in vitro cultures and physicochemical fractionation of O. volvulus extracts.

Characterization of an Onchocerca-Specific DNA Clone from Onchocerca Volvulus

The American Society of Tropical Medicine and Hygiene, 1987
A genomic library of a savanna isolate of Onchocerca volvulus was screened to detect recombinant plasm ids containing highly repeated DNA sequences of this parasite. Four recombinant plasmids were identified which hybridized specifically to Onchocerca DNA, but not to DNA from humans, black flies, Brugia malayi, B. pahangi, or Wuchereria bancrofti.

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 ...
