Abstract

We determined nucleotide sequences of the VP1 and 2AB genes and portions of the 2C and 3D genes of two evolving poliovirus lineages: circulating wild viruses of T geotype and Sabin vaccine-derived isolates from an immunodeficient patient. Different regions of the viral RNA were found to evolve nonsynchronously, and the rate of evolution of the 2AB region in the vaccine-derived population was not constant throughout its history. Synonymous replacements occurred not completely randomly, suggesting the need for conservation of certain rare codons (possibly to control translation elongation) and the existence of unidentified constraints in the viral RNA structure. Nevertheless the major contribution to the evolution of the two lineages came from linear accumulation of synonymous substitutions. Therefore, in agreement with current theories of viral evolution, we suggest that the majority of the mutations in both lineages were fixed as a result of successive sampling, from the heterogeneous populations, of random portions containing predominantly neutral and possibly adverse mutations. As a result of such a mode of evolution, the virus fitness may be maintained at a more or less constant level or may decrease unless more-fit variants are stochastically generated. The proposed unifying model of natural poliovirus evolution has important implications for the epidemiology of poliomyelitis.

  • They also appear to be largely independent of immune selection, as evolution rates are similar during prolonged replication in immunodeficient patients and during widespread circulation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
