onchocerciasis/carbohydrate

Antibodies to phosphorylcholine and carbohydrate determinants responsible for much of the cross-reactivity among nematodes are subclass restricted in humans and absent in the IgG4 subclass. Total IgG and IgG4 antibody responses to Onchocerca volvulus were examined by enzyme immunoassay and by

Cell-adhesion receptors mediate the interaction between host effector cells and cellular or multicellular targets, including opsonized parasites. Our recent finding of a deposition of plasma proteins, including fibronectin, on the surface of infective larvae of the helminthic parasite Onchocerca

Onchocerca volvulus polypeptides in the molecular mass range of 2.2 to 12.5 kD were separated by Tricine-SDS-PAGE and the serological recognition of these very low molecular weight antigens (VLMW-OvAg) was then investigated by immuno-blotting. Sera from 21 onchocerciasis patients as well as from 53

BACKGROUND A better understanding of reproductive processes in parasitic nematodes may lead to development of new anthelmintics and control strategies for combating disabling and disfiguring neglected tropical diseases such as lymphatic filariasis and onchocerciasis. Transcriptomatic analysis has

Diethylcarbamazine and suramin are the drugs of choice for the control of lymphatic filariasis and onchocerciasis respectively. Benzimidazoles, ivermectin, furapyrimidone, and isothiocyanates and their derivatives emerge as compounds of potential clinical interest as antifilarials.

Surface radioiodination of adult Onchocerca parasites reveals a restricted range of proteins associated with the cuticle. We present data to show that prominent among these is a complex of low-molecular-weight proteins which can be released in soluble form by homogenisation of surface-labelled

The filarial parasite Onchocerca volvulus is the causative agent of river blindness. In order to identify genes potentially involved in parasite development we cloned a zinc finger-encoding gene from this species. The ovzf-1 gene represents one member of a family of related zinc finger genes. The

Monoclonal antibodies directed to stage-specific surface antigens of Onchocerca gibsoni eggs were used in immunoradiometric assays to detect antigens in the sera of cattle infected with O. gibsoni. Two monoclonal antibodies detected antigens, presumably of egg origin, in sera. The target antigens
