Correlation of the virulence of Klebsiella pneumoniae K1 and K2 with the presence of a plasmid encoding aerobactin

Abstract

Nine isolates of Klebsiella pneumoniae belonging to capsular serotypes K1 and K2 were assayed for virulence in mice. Virulent isolates (50% lethal dose of less than 10(3) microorganisms) and avirulent isolates (50% lethal dose of over 10(6) microorganisms) were selected. Supplementation of a defined minimal medium with transferrin markedly reduced the growth of avirulent strains but had no significant effect on the growth of virulent strains. All isolates produced enterochelin, but only production of aerobactin could be correlated with virulence. The genes encoding aerobactin and its receptor protein were located on a 180-kilobase plasmid. They were cloned into the mobilizable vector pSUP202. Homology was demonstrated with the aerobactin operon of the Escherichia coli plasmid pColV-K30. Transfer of the recombinant plasmid pKP4 into an avirulent recipient enhanced virulence by 100-fold. These experiments demonstrated that aerobactin is an essential factor of pathogenicity in K. pneumoniae.

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.
