Abstract:

Hemagglutination inhibition reactions were used for examining sera of patients and donors 841 in all, in 4 towns Kemerovo, Kirov, Ussuriyisk, Leninogorsk and 2 rural districts of the USSR. In this reaction use was made of the antigens of group A viruses of the Western and Eastern horse encephalomyelitis and the Chikungunia virus and group B viruses sofyin virus strain of tick-borne encephalitis. In examining 386 sera obtained from urban residents, antibodies to group A viruses which have never formerly been registered in the USSR were detected in 7.5 per cent, and to group B viruses in 47.9 per cent of cases of 300 sera obtained from rural residents of the Eastern-Kazakhstan Region antibodies to group A virus to antigen of the Western horse encephalomyelitis were detected in 45 per cent, and to group B virus in 25 per cent of cases. Of the 155 sera obtained from the forestry workers of the Irkutsk Region antibodies of the antigen of the Eastern Horse encephalomyelitis were found in 26.4 per cent and to tick encephalitis 22.6 per cent of cases. Of the material collected in Eastern Kazakhstan the author succeeded in isolating on newborn mice a number of new viruses from birds, mosquitoes, and man identification of these viruses would show which of the group A viruses circulate in the given foci.
