Molecular Epidemiology of Polioviruses

Kew, Olen M., Nottay, Baldev K.·1984·Clinical Infectious Diseases

Abstract

Poliovirus isolates can be identified according to their genotypes with use of the technique of oligonucleotide fingerprinting. Fingerprint analysis is performed by cleaving the viral RNA genome with ribonuclease T1 and separating the fragments (oligonucleotides) in two dimensions. The larger, structurally unique oligonucleotides distribute into patterns ("fingerprints") highly characteristic of a specific overall RNA sequence. Isolates from the same epidemic have very similar fingerprints. Isolates from distinct epidemics have very different fingerprints, a consequence of the rapid evolution of polioviruses during replication in humans. Similarity in the fingerprints of case isolates provides independent evidence for epidemiologic linkage. Fingerprinting can readily distinguish vaccine-related isolates from wild strains. Contemporary vaccine-related isolates are very probably vaccine-derived because their fingerprints contain characteristic vaccine-strain oligonucleotide spots (types 1 and 3) and because their wild-type parents are unlikely to have survived largely unaltered in the natural environment. Some examples of applications of this technique within different epidemiologic settings are described.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Conclusive evidence for the vaccine origin of the Poland outbreak came from retrospective oligonucleotide fingerprinting and nucleotide sequencing studies of outbreak isolates.

    “conclusive evidence for the vaccine origin of the outbreak came from retrospective oligonucleotide fingerprinting (86) and nucleotide sequencing (118) studies of outbreak isolates.”

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.
