[The identification of alphaviruses by using cDNA probes complementary to the 3'-terminal of the viral genome].

Venezuelan equine encephalomyelitis, Eastern equine encephalomyelitis and Sindbis viruses, as well as members of various serological groups of alphaviruses were identified using synthesized molecular probes complementary to 3'-terminus of the molecule of the appropriate genomic RNA: 32P-single-stranded kDNA and E. coli-cloned 32P-double-stranded kDNA. A high species-specificity of kDNA-probes was demonstrated. The sensitivity of the method was 1 ng of viral RNA overlayed on the nitrocellulose filter.
