Genome sequencing revealed the uncommon location of the crossover site in the VP1 coding region (nucleotides 3251–3258 of Sabin 3 genome). The Sabin 2 donor sequence replaced the last 118 nt of VP1, resulting in the substitution of the complete antigenic site IIIa by PV2-specific amino acids. The low overall number of nucleotide substitutions in P1 region indicated that the predicted replication time of the isolate was about 8–9 weeks. Two of the principal determinants of attenuation in Sabin 3 genomes were mutated (U472C and C2493U), but the temperature-sensitive phenotype of the isolate was preserved. Our results support the theory that there exists a PV3/PV2 recombination hotspot site in the tail region of the VP1 capsid protein and that the recombination may occur soon after oral poliovirus vaccine administration.", }
