    This study evaluated several methods for subtyping herpes simplex virus (HSV) strains. The liver necrosis test in mice proved to be a simple, accurate, and useful screening tool for HSV typing.

    Area of Science:

    • Virology
    • Microbiology

    Background:

    • Herpes simplex virus (HSV) subtyping is crucial for epidemiological studies and understanding viral pathogenesis.
    • Accurate and efficient methods for differentiating HSV strains are essential for clinical and research applications.

    Purpose of the Study:

    • To evaluate and compare various techniques for subtyping herpes simplex virus (HSV) strains.
    • To identify reliable and reproducible methods for HSV strain differentiation.

    Main Methods:

    • Plaque morphology observation on chorio-allantoic membranes and green monkey kidney (GMK) cells.
    • Serological classification using K-values.
    • Pathogenicity studies in mice via intracerebral inoculation.
    • Investigation of thymidine's inhibitory effect on viral multiplication and heat-stability of viral thymidine kinases.

  • Association of focal liver necrosis in mice with serological typing results.

    • Main Results:

    • The liver necrosis test in mice demonstrated simplicity, accuracy, and utility as a screening typing-test.
    • Serological methods and assessment of viral thymidine kinase heat-stability yielded reliable typing results.
    • Other methods, including plaque morphology and thymidine inhibition, presented challenges in obtaining clear-cut or reproducible typing outcomes.

    Conclusions:

    • The liver necrosis test is a valuable screening method for HSV subtyping.
    • Serological typing and viral thymidine kinase heat-stability are reliable techniques for HSV strain differentiation.
    • Further optimization may be needed for other tested methods to achieve consistent typing results.
