The present invention relates inter alia to the treatment or prevention of influenza virus infection (including subtypes influenza A virus, influenza B virus, avian strain H5N1, A/H1N1, H3N2 and/or pandemic influenza) using compounds which inhibit the activity of p59-HCK and to a method of screening for a candidate drug substance intended to prevent or treat influenza virus infection in a subject, said method comprising identifying a test substance capable of inhibiting p59-HCK activity.

The present invention relates to a kit for detecting a virus, a composition for detecting a virus and a method for detecting a virus. According to the present invention, viruses may be detected with high efficiency at low cost within a short period of time.

The present invention provides, among other things, methods, reagents, and systems for the treatment, detection, analysis, and/or characterization of influenza infections.

A method for evaluating a biological material for unassociated virus-like particles virus size having a particular epitope uses a fluorescent antibody stain specific for binding with the epitope and a fluid sample with the virus-size particles and fluorescent antibody stain is subjected to flow cytometry with identification of fluorescent emission detection events indicative of passage through a flow cell of a flow cytometer of unassociated labeled particles of virus size including such a virus-like particle and fluorescent antibody stain.

The virus test device encompasses a pseudo-receptor film having pseudo-receptors mimicking a structure of a host-cell receptor, which binds specifically to a target virus, a virus introducing-tube for sucking down an air-under-test (AUT) containing the target viruses, to compress the AUT into a high-speed air-flow of aerosols-under-test, concentrating the target viruses contained in the AUT, and to eject the high-speed air-flow to the pseudo-receptor film, a signal conditioner for converting physical signals, which represent alterations of physical states of the pseudo-receptor film ascribable to specific bindings of the pseudo-receptors with the target viruses, to electric signals.

The present invention relates to hemagglutinin-specific antibodies, fragments thereof, and uses thereof. More specifically, these antibodies and fragments thereof are able to recognize antigen from multiple influenza strains.

Provided herein are methods and compositions related to Prevotella bacteria for the reduction of IL-8, IL-6, IL-Iβ, and/C or TNFα expression and/or for the treatment of viral infections.

Disclosed herein are methods for selecting an antibody fragment specific to an influenza virus. According to certain embodiments of the present disclosure, the influenza virus may be influenza virus type A (IAV) or influenza virus type B (IBV). Also disclosed herein are the selected antibodies, recombinant antibody produced from the selected antibodies, and the uses thereof in the diagnosis of influenza virus infection.

Novel Coronavirus/MERS-CoV/Influenza Virus A/B Multiple Rapid Detection Kit is disclosed. The kit has the advantages of high sensitivity, good specificity, high speed (3-15 minutes), simplicity and low cost.

A biosensor for detecting an influenza A virus in a sample is disclosed, which includes: an influenza A virus antibody immobilized on a surface of Au—Fe.sub.3O.sub.4 composite; where the antibody binds with the influenza A virus in the sample, which converts 4-methylumbelliferyl-N-acetyl-α-D-neuraminic acid (MUNANA) to 4-methylumbelliferone (4-MU), where the 4-MU emits green light at pH of 5.5-6.5; and wherein the 4-MU emits blue light at pH of 9.3-11.3. In the biosensor, 1,1′-oxalyldiimidazole chemiluminescence (ODI-CL) reagent may be utilized to emit the blue and green lights.
