    Insights

    Immune electron microscopy identified two influenza A virus strains using specific antisera. The indirect method demonstrated higher sensitivity for detecting immunocomplexes compared to the direct method.

    Area of Science:

    • Virology
    • Immunology
    • Microscopy

    Background:

    • Influenza A virus identification is crucial for public health.
    • Immune electron microscopy (IEM) is a valuable diagnostic tool.
    • Comparing direct and indirect IEM methods can optimize viral detection.

    Purpose of the Study:

    • To identify influenza A virus strains using IEM.
    • To compare the sensitivity of direct and indirect IEM methods.

    Main Methods:

    • Immune electron microscopy (IEM), both direct and indirect, was employed.
    • Specific rat and human convalescent antisera were used for identification.
    • Cross-testing involved various dilutions of virus and antisera to assess immunocomplex formation.

    Main Results:

    • Two influenza A virus strains, A/Chabarovsk/77 (H1N1) and A/Texas/77 (H3N2), were successfully identified.
    • The indirect IEM method exhibited higher sensitivity in demonstrating immunocomplexes.
    • This enhanced sensitivity was observed when using pig-anti-human-IgG serum compared to the direct method.

    Conclusions:

    • Indirect IEM is a more sensitive method for influenza virus identification.
    • The findings support the use of indirect IEM for improved viral detection and characterization.

    Immunofluorescence Microscopy

    A fluorescence microscope uses fluorescent chromophores called fluorochromes, which can absorb energy from a light source and then emit this energy as visible light. Fluorochromes include naturally fluorescent substances (such as chlorophylls) and fluorescent stains that are added to the specimen to create contrast. Dyes such as Texas red and FITC are examples of fluorochromes. Other examples include the nucleic acid dyes 4’,6’-diamidino-2-phenylindole (DAPI), and acridine orange.

    Immunogold Electron Microscopy

    Immunoelectron microscopy utilizes immunogold labeling of endogenous proteins with specific antibodies to detect and localize these proteins in cells and tissues. The procedure provides insights into the distribution and quantification of protein under different stimulation conditions offering clues about their functions. Conjugating highly electron-dense gold particles with primary or secondary antibodies allow antigen detection on and within cells, with high resolution and specificity.
