[Molecular evolution and genotype classification of TT virus].

Based on sequences data, TTV have a partial Rep protein motifs found among Circoviridae and the conserved region of parvoviral nonstructural polypeptides (NS)-1 genes, however we could not perform phylogenetic analyses among TTV and other viruses because of few similar sequences. Putative ORF2 among G2 and G4 encoded 49 aa because of in-frame stop codon, although that of G1 encoded 202 aa. Just down-stream of the stop codon, another putative new ORF(ORF3) were found around 150 aa. A phylogenetic analysis, using the ORF1 sequences of 93 TTV obtained from various geographical areas, indicated that the virus could be classified into six different genotypes. Further studies using more than 350 isolates obtained from DDBJ showed at least nine genotypes.

To the antigenic classification of some viruses from the tick-borne encephalitis complex by monoclonal antibodies.

Two monoclonal antibodies (MoAb) to the Skalica virus from the tick-borne encephalitis (TBE) complex were used to compare Karshi and Royal Farm viruses with the Russian spring-summer encephalitis, Central European encephalitis (Hypr and Kumlinge strains) Skalica, Langat and Powassan viruses. The first MoAb was prepared by fusion of P3NS1 cells with BALB/c mouse spleen cells, immunized with the Skalica virus; it was of IgM class and reacted in haemagglutination-inhibition (HI) test (MoAb type 1). The second MoAb was of IgG class and reacted in complement-fixation (CF) test (MoAb type 2). MoAb type 1 reacted in the HI test with Russian spring-summer encephalitis (RSSE), Central European encephalitis (CEE) virus strains, Skalica and Langat viruses. No reaction was observed with Powassan, Karshi, and Royal Farm viruses. MoAb type 2 reacted in the CF test with all members of tick-borne encephalitis complex except the Powassan, Karshi, and Royal Farm viruses.
