Prevalence of antibodies to arboviruses in various animals in Israel.

A serological survey of the prevalence of arbovirus antibodies in various mammals and birds was made in Israel during the years 1959-60, employing the haemagglutination-inhibition technique and using group-A and group-B antigens. High proportions of the animals of several species were found to be positive to group-B arboviruses. Most of these animals showed higher titres against the West Nile virus than against that of turkey meningoencephalitis, but in some cases there were higher titres against the latter virus. Group-A positive sera were also encountered, but in a smaller proportion of the tested animals. Most of the group-A positive sera were also group-B positive, and very few were group-A positive only.
