In St. Lawrence County, New York State, in 1964-65, 7, 940 Culicids, Ceratopo-gonids, Simuliids and Tabanids were tested in 769 pools for evidence of virus infection. One of 51 pools of Aedes cinereus Mg. yielded a virus of the California encephalitis complex of a type different from the prototype strain. Antibodies neutralizing California encephalitis virus were found in serum from man, cattle and wild animals in 11 counties of New York.

Arbovirus Reactivity in Serum from Amphibians, Reptiles, Birds, and Mammals0 aArthropodbornevirus Survey in St Lawrence County New York Arbovi a645-6500 v173 aSerological evidence of the presence of groups A, B and Bunyamwera arboviruses in New York State has been reported [Bull Hyg., 1964, v. 39, 75; Am. J. Vet. Res., 1965, v. 26, 914]. In continuation of these studies a further 901 wild animal sera (amphibian, reptilian, avian and mammalian) and 192 human sera were obtained from St. Lawrence County and tested for the presence of haemagglutination inhibiting (HI) and neutralizing (NT) antibodies. Group A reactivity was tested against eastern and western encephalomyelitis viruses, group B reactivity with Powassan and St. Louis encephalitis viruses, while the Bunyamwera group was represented by Cache Valley in NT tests and by Maguari virus in HI tests.
Only a few reactions with group A viruses were found, but there was evidence of considerable activity by group B viruses-particularly Powassan virus. Of 70 sera from woodchucks (Marmota monax), 38 had both NT and HI antibodies against Powassan virus and sera from 9 other mammalian species were also reactive. Despite this high incidence in animal sera, only 2 human sera gave evidence suggesting previous infection with group B arboviruses; one had antibodies to Powassan and the other to St. Louis encephalitis virus. In the Bunyamwera group, 9 of 192 human sera neutralized Cache Valley virus, but no antibodies to this group of viruses were found in any of the 901 animal sera.

Powassan virus was also isolated from tissues taken from the same 2 animals. Another strain of POW virus was recovered from the brain of a sick gray fox found in Broome County 200 miles to the south in New York State. The 2 tick strains were compared antigenically with the proto-type POW strain and were found to be antigenically similar.
