Abstract

A total of 35 coliforms isolated from bovine intramammary infections were tested for serum susceptibility. Growth responses of Klebsiella pneumoniae isolated from intramammary infections originating during the dry period were inhibited more than were growth responses of Klebsiella pneumoniae isolated from infections originating during lactation. Escherichia coli growth responses did not differ between isolates originating from dry period and lactational intramammary infections. Mean growth responses to serum did not differ between Klebsiella pneumoniae and Escherichia coli. Bactericidal properties of serum were due to complement activity. The classical pathway of complement appeared to be the principal source of bactericidal activity of serum toward Klebsiella pneumoniae. Alternative and classical pathways of complement were both important for bactericidal effects of serum on Escherichia coli. Iron saturation of serum did not affect growth responses of either Klebsiella pneumoniae or Escherichia coli. These data illustrate that coliforms isolated from intramammary infection originating during the dry period were not more resistant to the bactericidal activity of bovine serum than were coliforms isolated from intramammary infection occurring during lactation.

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

  • Resistance to the bactericidal activity of serum is a virulence factor common to many coliform bacteria causing clinical mastitis, but is not a prerequisite for pathogenicity.

    “Resistance to the bactericidal activity of serum is a virulence factor common to many coliform bacteria causing clinical mastitis, but is not a prerequisite for pathogenicity [14, 26, 36, 52].”

    From Coliform mastitis (2003) · cites this paper as [26]

    The Discussion (page not available in our copy) says that both serum-resistant and serum-susceptible coliforms were isolated from naturally occurring intramammary infections, directly supporting that resistance is not a prerequisite. The Introduction reports an association with virulence in experimentally induced mastitis, but the paper does not establish that serum resistance is a common virulence factor specifically among bacteria causing clinical mastitis; its isolates are described as coming from intramammary infections. (LLM, conf=0.84)

    Experimental — accuracy not yet measured

  • Serum resistance does not differ between coliforms isolated from intramammary infections originating during the dry period and strains creating infections that originate during lactation.

    “However, serum resistance does not differ between coliforms isolated from intramammary infections originating during the dry period and strains creating infections that originate during lactation [26].”

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.
