Experimental infection of fattened pigs with rotavirus antigens and coproantibodies excretion in feces

Experimental infection of fattened pigs with rotavirus antigens and coproantibodies excretion in feces

Annales de Recherches Veterinaires 15(3): 425-436

Fattened pigs were experimentally infected with porcine rotavirus (OSU strain). Viral antigens in the feces were analyzed over a period of 2 mo. (ELISA [enzyme-linked immunosorbent assay] method). There was no correlation between virus excretion and the clinical manifestation of disease. The local immunity was analyzed in the feces by the detection of antirotavirus IgG, IgM and IgA and immune complexes using the ELISA. The level of IgA was higher (10-fold) than IgG and IgM, and the timing of the appearance of these antibodies antivirus was also different. No correlation was found between local immunity and virus excretion in the feces.
