Abstract

As shown in many intervention studies, probiotic bacteria can have a beneficial effect on rotavirus and HIV-induced diarrhoea. In spite of that fact, antiviral effects of probiotic bacteria have not been systematically studied yet. Non-tumorigenic porcine intestinal epithelial cells (IPEC-J2) and alveolar macrophages (3D4/2) were treated in different experimental designs with probiotic and other lactic bacteria and their metabolic products. Vesicular stomatitis virus (VSV) was used in the study as a model virus. Cell survival and viral inhibition were determined by antiviral assay and confirmed by immunofluorescence. Pre-incubation of cell monolayers with probiotic bacteria reduced viral infectivity up to 60%. All bacteria used prevented VSV binding to the cell monolayers by direct binding of VSV to their surface. Probiotic and other lactic bacteria prevented viral infection also by establishment of the antiviral state in pre-treated cell monolayers. Probiotic and other lactic bacteria secreted antiviral substances during their growth, as the infectivity of the virus was diminished by 68% when bacterial supernatants were tested. It was shown for the first time that probiotic and other lactic bacteria exhibit an antiviral activity in a cell culture model. Possible mechanisms of antiviral activity include: 1) hindering the adsorption and cell internalisation of the VSV due to the direct trapping of the virus by the bacteria, 2) "cross-talk" with the cells in establishing the antiviral protection and 3) production of metabolites with a direct antiviral effect.

  • Strains of Lactobacillus and Bifidobacterium interfere with attachment and entry of vesicular stomatitis virus into cells in a cell culture model, possibly by steric hindrance.

    “Strains of Lactobacillus (sensu lato) and Bifidobacterium have been shown, in a cell culture model, to interfere with attachment and entry of vesicular stomatitis virus into cells, possibly by steric hindrance (Botić et al., 2007).”

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.
