Abstract

Increases in the incidence and severity of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections have spawned efforts to define unique virulence properties among prevalent strains. Panton-Valentine leukocidin (PVL), a pore-forming cytotoxin, has garnered attention because of its epidemiologic association with CA-MRSA. Using both the clinical isolate LAC, which is representative of the epidemic USA300 strain, and its isogenic PVL-negative strain in murine models of staphylococcal skin infection and pneumonia, we expanded upon recent studies by assessing the contribution of PVL in the genetic background of BALB/c mice. The data presented in this report support the observation that PVL does not contribute to the pathogenesis of staphylococcal infection of mice.

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

  • Other virulence factors that are common in these clones are likely responsible for the mouse phenotype.

    “Since PVL seems to have few effects on virulence in both primary and secondary mouse pneumonia models [22,50], other virulence factors that are common in these clones are likely responsible for the mouse phenotype.”

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.
