Fattened pigs were experimentally infected with porcine rotavirus (OSU strain). Viral antigens found in the faeces were analysed over a period of two months (ELISA method). We have found no correlation between virus excretion and the clinical manifestation of disease. The local immunity has been analysed in the faeces by the coproantibodies antirotavirus. The different classes of antibody, G, M, A and immune complexes have been determined using the ELISA method. The level of IgA antibodies 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 faeces.
