Different suitability of 3 filarial antigens (Litomosoides carinii, Dipetalonema viteae, Dirofilaria immitis) to act as allergens in the Passive Cutaneous Anaphylaxis Test and to serve as antigens in an ELISA in the course of experimental filarial infections (L. carinii, D. viteae, Brugia malayi, B. pahangi) of Mastomys natalensis.
Crude extracts of adult worms of 3 different filariae (Litomosoides carinii, Dipetalonema viteae, Dirofilaria immitis) were evaluated for their suitability to serve as allergens in the Passive Cutaneous Anaphylaxis Test (PCA) and as antigens in an ELISA which detected mainly IgG antibodies. Studies were done in the course of 4 different filarial infections (L. carinii, D. viteae, Brugia malayi,...

متن کاملStudies on Dipetalonema viteae (Filarioidea) I. Microfilaraemia in hamsters in relation to worm burden and humoral immune response.
The course of a primary infection with Dipetalonema viteae was studied in one randomly bred and in one inbred strain of hamster. Worm recovery and the duration and intensity of the microfilaraemia were analyzed and related to the humoral immune response of the host by using the indirect immunofluorescent antibody test on frozen sections of female worms, on eggs and on intact microfilariae. The ...
متن کاملSerum immunoglobulin and antibody levels and the passive transfer of resistance in hamsters infected with Dipetalonema viteae.
Clearance of microfilariae from the circulation of hamsters infected with Dipetalonema viteae was demonstrated following passive transfer of serum obtained from hyperinfected hamsters. The exclusion fraction after gel filtration of this serum on Sephacryl S 200 also cleared microfilariae whereas the other fractions did not. There was no clearance with serum taken during the pre-patent, patent o...
