Etude d'un extrait antigènique de la filaire sélaria labiatopapillosa en double diffusion et en immunoelectrophorèse appliqué au diagnostic immunologique des filarioses

The detection of antibodies in human and animal filariases by counterimmunioelectrophoresis with Dirofilaria immitis antigens

“…bancrofti microfilaraemia investigated by Kauffer's group. That there may be a broad spectrum of antigenic specificity is indicated by the investigation of Niel et al (1972) who found that the antigens prepared from Setaria labiato-papillosa and Dipetalonema viteae produced precipitin arcs, by double diffusion and IEP, when reacted against the serum of patients with loiasis, onchocerciasis, bancroftian filariasis, and dracunculiasis. It should also be noted that these authors reported positive precipitin reactions with an antigen of Ascaris suum and the sera from these filariasis patients.…”

Immunodiagnosis of human filariasis by counterimmunoelectrophoresis using Litomosoides carinii antigens

“…The observations made in the study also indicate that clinical bancroftian filariasis, without detectable microfilariae in the peripheral blood, can be diagnosed by serological means using L. carinii antigen/antibody system. Although the use of such a system still make the interpretation of serological reactions difficult mainly because of the cross-antigenicity between filarial and other intestinal parasites (Desowitz and Una, 1976;Niel et al^ 1972), the sensitization of human beings to vector mite and filaria-like manifestations caused by some other conditions (Price, 1974) may perhaps be eliminated.…”
