Serotyping herpes simplex virus isolated by enzyme-linked immunosorbent assays

Area of Science:

• Virology
• Immunology
• Diagnostic Assays

Background:

• Herpes simplex virus (HSV) serotyping is crucial for clinical diagnosis and management.
• Traditional neutralization tests for HSV serotyping are time-consuming and require specialized expertise.
• A need exists for a rapid, accurate, and accessible method for HSV typing.

Purpose of the Study:

• To develop and validate an enzyme-linked immunosorbent assay (ELISA) for serotyping HSV isolates.
• To compare the efficacy of the developed ELISA with standard neutralization tests.
• To assess the convenience and accuracy of ELISA for routine clinical use.

Main Methods:

• Development of a double-antibody sandwich ELISA technique.
• Utilization of cross-absorbed rabbit immunoglobulin for specific serotype differentiation.
• Testing of both stock HSV cultures and 32 clinical isolates.
• Comparison of ELISA results with those from standard neutralization tests.

Main Results:

• The ELISA method demonstrated high agreement with the standard neutralization test for HSV typing.
• Clear differentiation between HSV-1 and HSV-2 serotypes was achieved.
• The assay proved effective for both laboratory stock cultures and clinical isolates.
• ELISA requires minimal antigen, antibody, and simple equipment.

Conclusions:

• The developed ELISA is a convenient and accurate method for serotyping herpes simplex virus.
• This assay serves as a viable and efficient substitute for conventional neutralization tests.
• ELISA offers a simplified approach to HSV typing in clinical settings.
