Role of Neuraminidase in Lethal Synergism between Influenza Virus and Streptococcus pneumoniae

Open access

Abstract

A lethal synergism exists between influenza virus and Streptococcus pneumoniae, accounting for excess mortality during influenza epidemics.Using a model of viral-bacterial synergism, we assessed the role that the influenza virus neuraminidase (NA) has in priming mice for pneumococcal infection.Administration of the selective NA inhibitor oseltamivir improved survival, independent of viral replication and morbidity from influenza.Both pathologic examination of the lungs and live imaging of pneumonic lesions, using a bioluminescent pneumococcus, suggested that the effect of NA inhibition was to limit the extent of pneumococcal pneumonia during early infection.Adherence assays and immunohistochemical staining for sialic acids in lungs from infected mice demonstrated that the influenza virus NA potentiates development of pneumonia by stripping sialic acid from the lung, thus exposing receptors for pneumococcal adherence.Selective NA inhibitors may be useful clinically to interrupt this novel mechanism of synergism and to prevent excess mortality from secondary bacterial pneumonia.A synergism exists between influenza virus and bacterial pathogens, accounting for excess mortality during influenza epidemics [1-3].Combined, influenza and pneumonia rank as the sixth leading cause of death worldwide and as the leading infectious cause of death [4].The impact of interventions against influenza and Strepto-

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.
