Detection of antibodies to alphaviruses and flaviviruses in some migratory birds of the Danube Delta.

Data are reported on the presence of antibodies to some group A(alphavirus) B(flavivirus) arboviruses in 8 species of migratory birds (Ardea cinerea, Plegadis falcinellus, Anas querquedula, Anser albifrons, Gavia arctica, Fulica atra, Larus minutes and and Phalacrocorax corbo) of the Danube Delta.

Investigations on the presence of antibodies to several flaviviruses in humans and some domestic animals in a biotope with a high frequency of migratory birds.

Data are reported on the presence of HAI antibodies to several flaviviruses (tick-borne encephalitis, West Nile, and Ntaya viruses) in humans and some domestic animals in a biotope with a high frequency of migratory birds. The results obtained prove the presence in humans of specific antibodies in a proportion of 11.8% to tick-borne encephalitis and of 25.5% to West Nile and Ntaya antigens. Among domestic animals it was only possible to detect antibodies to West Nile (4.9% in sheep, 4.1% in cattle, and 12% in goats) and to Ntaya antigens (1.9% in sheep, 1.6% in cattle, 8% in goats, and 13.9% in swine).
