Enzyme immunoassays for viral diseases.

Area of Science:

• Virology
• Immunology
• Biotechnology

Background:

• Viral diseases pose significant challenges in human and animal health.
• Accurate diagnostic tools are essential for disease surveillance and control.
• Enzyme-linked immunosorbent assays (ELISA) offer a versatile platform for detecting viral infections.

Purpose of the Study:

• To investigate the application and standardization of microplate enzyme-linked immunosorbent assays (ELISA) for viral disease detection.
• To evaluate ELISA's efficacy in rubella diagnosis and its comparison with traditional methods.
• To explore ELISA's broader applications in human, veterinary, and plant virology.

Main Methods:

• Standardization of critical ELISA components: carrier plates, antigens, conjugates, and substrate.
• Comparative analysis of ELISA results against hemagglutination-inhibition tests for rubella.
• Application of ELISA in an epidemiological study for rubella surveillance.
• Assay of antibodies against various viruses including cytomegalovirus, measles, adenovirus, coxsackieviruses, and herpesviruses using ELISA.

Main Results:

• Standardization of components was identified as essential for reliable ELISA performance.
• ELISA demonstrated comparable and reliable results to hemagglutination-inhibition tests for rubella.
• ELISA successfully detected antibodies against a range of human viruses.
• The study confirmed ELISA's utility in veterinary diagnostics for respiratory syncytial virus and Newcastle disease virus, as well as for plant viruses.

Conclusions:

• Standardized microplate ELISA is a robust and essential method for accurate viral disease diagnosis.
• ELISA is a versatile tool applicable across human, veterinary, and plant virology.
• The findings support the widespread adoption of ELISA for viral disease surveillance and research.
