[Use of serologic methods for identifying and classifying some alpha-viruses]. / Ispol'zovanie serologicheskikh metodov dlia identifikatsii i sistematizatsii nekotorykh al'fa-virusov.

Sindbis group viruses can be indirectly identified and classified. Three antigenic subtypes were distinguished by solid-phase enzyme immunoassay (SPEIA): African, West-Asian, and North-European. The negative plaque suppression test is recommended for identification of new Alphavirus strains for detecting species-specific antigenic determinants, and SPEIA for classification by appurtenance to antigenic subtypes.
