title: Prevalence of arbovirus antibodies in sera of animals in Sri Lanka.
abstract: The sera of cattle, goats, dogs and crows from the Colombo area were tested for antibodies against seven arboviruses of the families Togaviridae and Bunyaviridae by a plaque-reduction neutralization microtest, using Vero cells and a stable line of pig kidney (PS) cells. The overall percentages of positive sera among the mammals were: Bhanja, 92.5%; Calovo (Batai), 30.6%; Sindbis, 13.8%; Langat, 4.8%; Tahyna, 3.9%; West Nile, 1.6%. Among the birds, 23.8% had antibodies to Bhanja virus and 9.5% to Sindbis. No antibodies against tick-borne encephalitis virus were found. The results show that at least two members of the Bunyaviridae family (Bhanja and Calovo) are highly endemic in Colombo.
