École nationale vétérinaire, 94i01 Maisons dlfovt RÉSUMÉ Quatre souches d'entérovirus du groupe I (Teschen-Talfan) ont été isolées à partir de petites enzooties de poliomyélite du Porc. La maladie et les lésions ont été reproduites chez le porcelet. La preuve est donc apportée de l'existence de la maladie de Talfan en France. SUMMARY ISOLATION OF THE TAI,FAN DISEASE VIRUS IN FRANCE Four strains of the enterovirus of group I (Teschen-Talfan) have been isolated from small enzooties of swine polyomyelitis. The disease and its lesions have been replicated in the piglet. Thus, the existence of Talfan's disease in France is proved.

Cell biological and molecular characteristics of pseudorabies virus infections in cell cultures and in pigs with emphasis on the respiratory tract

“…In contrast, the 75V19 strain, which was isolated during a severe PrV outbreak with respiratory, nervous and reproductive problems in 1975, was replicating to higher titers in the respiratory tract compared to the NS374, gave a clear viremia and was replicating in different regions of the central nervous system. Similar observations of increased virulence were done in other West European countries [1,50,66]. The basis for the increased virulence is not known.…”
