Abstract
In order to test the hypothesis that RNA structural elements promote the distribution of certain types of recombination junctions in each one of the 2C and 3D poliovirus genomic regions (Sabin 3/Sabin 2 or Sabin 1 in 2C and Sabin 2/Sabin 1 or Sabin 3 in 3D), we searched in 2C and 3D regions of reference Sabin strains for high probability RNA structural elements that could promote recombination. Recombination junctions that were identified in clinical strains of this study, as well as in clinical strains of previous studies, were superimposed on RNA secondary structure models of 2C and 3D genomic regions. Furthermore, we created an in vitro model, based on double infection of cell-culture with two poliovirus strains, for the production and identification of recombinant Sabin strains in 2C and 3D regions. Our intention was to compare the results that refer to the correlation of recombination junctions and RNA secondary structures in 2C and 3D regions of clinical strains, with the respective results of the in vitro model. Most of the recombination junctions of the clinical strains were correlated with RNA secondary structure elements, which were identical between recombining Sabin strains, and also presented high predictive value. In consensus were, the respective results originated from the in vitro model. We propose that the distribution of specific types of recombination junctions in certain regions of Sabin strains is not fortuitous and is correlated with RNA secondary structure elements identical to both recombination partners. Furthermore, results of this study highlight an important role for the stem region of the RNA structure elements in promoting recombination.

Abstract
Five oral poliovirus vaccine (OPV) strains carrying an intertypic PV3/PV2 recombination in VP1 capsid protein were isolated during poliovirus surveillance. These five PV3 strains had altogether four diverse recombination crossover points near the 3' end of the VP1 coding region. The complete antigenic site IIIa was replaced by PV2-specific amino acids in four of the studied PV3 strains. Low overall number of nucleotide substitutions in VP1 indicated that the predicted replication time, "age", of the PV3 strains was short, 6 months or less. The nucleotide 472-T in the 5' non-coding region, associated to the attenuated phenotype of PV3/Sabin, was reverted to wild-type C in all studied PV3/PV2 recombinant strains. Three of the PV3 strains had at least a tripartite genome deduced from the partial 3D polymerase-coding region sequences. Our results suggest that there exists a PV3/PV2 recombination hot-spot site in the 3' partial region of the VP1 capsid protein and that the recombination may occur within weeks or a few months after the administration of OPV.

Abstract
An echovirus 3 (Echo3) strain (strain LR31G7) was isolated from a sewage treatment plant in Greece in 2005. Full-genome molecular, phylogenetic, and SimPlot analyses were conducted in order to reveal the evolutionary pathways of the isolate. Nucleotide and phylogenetic analyses of part of the VP1 genomic region revealed that the isolated strain correlates with Echo3 strains isolated during the same year in France and Japan, implying that the same virus circulated in Europe and Asia. LR31G7 was found to be a recombinant that shares the 3' part of its genome with an Echo25 strain isolated from asymptomatic infants in Norway in 2003. Nucleotide and SimPlot analyses of the VP1-2A junction, where the recombination was located, revealed the exact recombination breakpoint (nucleotides 3357 to 3364). Moreover, there is evidence that recombination events had occurred in 3B-3D region in the evolutionary history of the isolate. Our study indicates that recombination events play major roles in enterovirus evolution and that the circulation of multirecombinant strains with unknown properties could be potentially dangerous for public health.

Abstract
Attenuated strains of Sabin poliovirus vaccine replicate in the human gut and in rare cases may cause vaccine-associated paralytic poliomyelitis (VAPP). Mutations at specific sites of the genome and recombination between Sabin strains may result in the loss of the attenuated phenotype of OPV (Oral Poliovirus Vaccine) strains and the acquisition of traits characteristic of wild polioviruses, such as increased neurovirulence and loss of temperature sensitivity. In this study, we determined the phenotypic traits such as temperature sensitivity and growth kinetics of eight OPV isolates (six bi-recombinant and two non-recombinant). The growth phenotype of each isolate as well as of Sabin vaccine strains in Hep2 cell line at two different temperatures (37 and 40 degrees C) was evaluated using two different assays, RCT test (Reproductive Capacity at different Temperatures) and one-step growth curve analysis. Moreover, the nucleotide and amino acid positions in the genomes of the isolates that have been identified as being involved in the attenuated and thermo sensitive phenotype of Sabin vaccine strains were investigated. Mutations that result in loss of the attenuated and thermo sensitive phenotype of Sabin vaccine strains were identified in the genomes of all isolates. Both mutations and recombination events correlated well with the reverted phenotypic traits of OPV-derivatives. In the post-eradication era of wild polioviruses, the identification and the characterization (genomic and phenotypic) of vaccine-derived polioviruses become increasingly important in order to prevent cases or even outbreaks of paralytic poliomyelitis caused by neurovirulent strains.

Abstract
In the post-eradication era of wild polioviruses, the only remaining sources of poliovirus infection worldwide would be the vaccine-derived polioviruses (VDPVs). As the preponderance of countries certified to be polio-free has switched from OPV (oral poliovirus vaccine) to IPV (inactivated poliovirus vaccine), importation of recombinant evolved derivatives of vaccinal strains would have serious implication for public health. To test the robustness of the proposed RT-PCR screening analysis, eleven recombinant vaccine-derived polioviruses that were characterized previously by sequencing by our group, in addition to three recently identified recombinant environmental isolates were assayed. Although the most definitive characterization of VDPVs is by genomic sequencing, in this study we describe a new, inexpensive and broadly applicable RT-PCR assay for the identification of the predominant recombination types S3/Sx in 2C and S2/Sx in 3D genomic regions respectively of VDPVs, that can be readily implemented in laboratories lacking sequencing facilities as a first approach for the early detection of vaccine-derived poliovirus (VDPVs).

Abstract
A type 2 vaccine-related poliovirus (strain CHN3024), differing from the Sabin 2 strain by 0.44% in the VP1 coding region was isolated from a patient with vaccine-associated paralytic poliomyelitis. Sequences downstream of nucleotide position 6735 (3D(pol) coding region) were derived from an unidentified sequence; no close match for a potential parent was found, but it could be classified into a non-polio human enteroviruses species C (HEV-C) phylogeny. The virus differed antigenically from the parental Sabin strain, having an amino acid substitution in the neutralizing antigenic site 1. The similarity between CHN3024 and Sabin 2 sequences suggests that the recombination was recent; this is supported by the estimation that the initiating OPV dose was given only 36-75 days before sampling. The patient's clinical manifestations, intratypic differentiation examination, and whole-genome sequencing showed that this recombinant exhibited characteristics of neurovirulent vaccine-derived polioviruses (VDPV), which may, thus, pose a potential threat to a polio-free world.
