Bacterial biofilm in upper respiratory tract infections

Morris, David P.·2007·Current Infectious Disease Reports

Abstract

The upper respiratory tract is of easy access to pathogens, and although it has evolved a number of defensive barriers to avoid invasion, acute and chronic infections of the ears, nose, and throat are common and present a huge challenge to the healthcare system. Though most infections are viral, mild, and self-limiting, bacterial infection is responsible for considerable morbidity and has potential for life-threatening sequelae. Biofilms form when free-floating planktonic organisms adhere to a surface. Within a polymicrobial, biofilm organisms interact, exchanging metabolites, enzymes, and genetic material. The colony is protected, allowing bacteria to thrive in otherwise unfavorable conditions. A role for the biofilm in upper respiratory tract infections has been proposed because infections often run a persistent, remitting course, samples are sometimes difficult to culture, and resistance to medical management is common. This review presents recently published evidence of bacterial biofilms in established upper respiratory tract infections.

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?

  • RSV interaction with TLR2 and TLR6 promotes a proinflammatory response.

    “It has been shown that the RSV fusion protein interacts with TLR4, which then signals through MyD88 to induce immune responses in airway epithelial cells (28, 92, 103, 152), and a recent study demonstrated RSV interaction with TLR2 and TLR6, promoting a proinflammatory response (190).”

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.
