| Abstract: | Sera from birds of the order Anseriformes in Czechoslovakia were examined for virus neutralizing (VN) antibodies to arboviruses. VN antibodies to Sindbis, Calovo and Tahyna viruses were found in 15, 5 and 6 out of 106 greylag goose (Anser anser) sera. Out of 38 ducks, 6 mallards (Anas platyrhynchos) and 1 garganey (Anas querquedula) contained VN antibodies to Sindbis virus, 6 mallards to Calovo virus, 4 mallards and 1 garganey to Tahyna virus, 2 mallards and 1 garganey to tick-borne encephalitis (TE) virus and 1 mallard to West Nile (WN) virus. |
