Genetic Diversity and Structure in Escherichia coli Populations

Selander, Robert K., Levin, Bruce R.·1980·Science

Abstract

A survey of electrophoretic variation in 20 enzymes from 109 clones of Escherichia coli from natural populations yielded an estimate of mean genetic diversity approximately twice that reported in an earlier study and four to five times larger than estimates for most eukaryotic species. Despite this extensive variability, the number of distinctive genotypes apparently is rather limited. Identical clones were obtained from unassociated hosts, and a clone that is electrophoretically indistinguishable from the laboratory strain Escherichia coli K-12 was isolated from a human infant. The results suggest that rates of genetic recombination in natural populations of Escherichia coli are low. These findings have implications for our understanding of the genetic structure of Escherichia coli populations and the factors determining the amount of neutral gene variability in this bacterial species.

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.
