[Serological demonstration of experimental round worm infections-Ascaris suum, Toxocara canis--in swine by means of the indirect immunofluorescence antibody test].
By means of indirect immunofluorescent antibody reaction (IFAR), using serum of experimentally infected pigs, various antigens were studied with regard to their usefulness for serological verification of prepatent Ascaris suum and Toxocara canis infections. Eggs, egg larvae, larvae received from livers, lungs and brains of experimentally infected white mice and sections of adult T. canis as well as eggs, egg larvae, liver larvae and sections of frozen adult A. suum proved to be not suitable for the reliable serum diagnosis of the infections. On the other hand, A. suum larvae, isolated from lungs of white mice or guinea pigs days after experimental infection, represent an antigen applicable to IFAR for the evidence of prepatent A. suum infections in pigs. The antigen, stored at -20 degree C, is durable without substantial impairment of its reactivity at least 7 months.
