 #9400 Acanthocheilonema viteae IgG ELISA
ELISA kit for the diagnosis of human filariasis

Parasitology and clinical relevance

Human filariasis are caused by a variety of nematodes (Loa Loa, Onchocerca volvulus, Dracunculus medinensis, Wuchereria bancrofti, Brugia malayi). The diagnosis is based on clinical evidences, an history of living in an endemic area, hypereosinophilia and the detection of microfilariae. The finding of an adult filaria is a proof of infection but is frequently unsuccessful. Serological methods using indirect immunofluorescence assays on frozen sections of adult worms of animal origin (Acanthocheilonema viteae, Dirofilaria immitis, Setaria sp.) and immuno-electrophoresis can both help for diagnosis. These methods are often positive in cases of occult filariasis or when microfilaremia is negative, they are less sensitive in patients with detectable microfilariae. Our ELISA assay uses also the antigenic homologies observed between human and animal filariae. The ELISA procedure is more reproducible and less tedious than IFA on worm sections.


96 determinations of IgG antibodies using standard methodologies.

Wells sensitized with somatic antigens from adult females of Acanthocheilonema viteae.

8-wells polystyrene breakable strips: useful and economic format for laboratories with a small workload.

CE registration: H-CH/CA01/IVD/01755

Sensitivity and specificity

Sensitivity of 95% with sera of suspected and confirmed cases of filariasis.

Specificity of 98% with sera of blood donors (from Switzerland).

Crossreactivities are found in cases of trichinellosis, hydatidosis, fascioliasis, ankylostomiasis and strongyloidiasis (40 to 83%).
