ANTIBODIES TO ALPHAVIRUS, FLAVIVIRUS, AND BUNYAVIRUS ARBOVIRUSES IN-HOUSE SPARROWS (PASSER-DOMESTICUS) AND TREE SPARROWS (PARUS-MONTANUS) IN POLAND

Sparrows from central Poland were examined by a hemagglutination-inhib ition test (titer greater than or equal to 20) for the presence of ant ibodies to arboviruses, between 1995 and 1996. In house sparrows (Pass er domesticus) (n = 179), antibodies to Sindbis, West Nile, tick-borne encephalitis, Tahyna, and Calovo viruses were detected at seroprevale nces of 1.1%, 2.8%, 1.1%, 2.8%, and 1.1%, respectively. In tree sparro ws (P. montanus) (n = 33), antibodies to the Sindbis, West Nile, and T ahyna viruses were detected at seroprevalences of 9.1%, 12.1%, and 3.0 %, respectively.
