"Swine influenza has not caused any serious health or economic losses in the Czech Republic since the end of the 1960's. No manifestations of this disease have been confirmed in pig herds during the last ten years, with the exception of a single virus isolation in 1992 and detection of antibodies against human influenza in 1996 following the 1995 human epidemic. In 2000, swine influenza virus was isolated from feeder pigs on a large farm with nearly 10 000 animals. The infection was determined by cultivation of nasal swabs in the allantoid sac of nine-day-old chick embryos and by serological examination in the haemagglutination-inhibition test. The virus isolated from the chick embryos was tested against specific antisera and classified as possessing type H1 haemagglutinin. The cultivation finding was confirmed by a significant increase in antibody levels found in sera collected three weeks after the outbreak of infection. The reactions of these sera with selected antigens showed that the virus was clo" . . "5"^^ . "Posp\u00ED\u0161il, Zden\u011Bk" .
