Development and application of a colloidal-gold immunochromatographic strip for detecting Getah virus antibodies.

Abstract: Getah virus (GETV) is a re-emerging mosquito-borne alphavirus that is highly pathogenic, mainly to pigs and horses. There are no vaccines or treatments available for GETV in swine in China. Therefore, the development of a simple, rapid, specific, and sensitive serological assay for GETV antibodies is essential for the prevention and control of GETV. Current antibody monitoring methods are time-consuming, expensive, and dependent on specialized instrumentation, and these features are not conducive to rapid detection in clinical samples. To address these problem, we developed immunochromatographic test strips (ICTS) using eukaryotically expressed soluble recombinant p62-E1 protein of GETV as a labelled antigen, which has good detection sensitivity and no cross-reactivity with other common porcine virus-positive sera. The ICTS is highly compatible with IFA and ELISA and can be stored for 1 month at 37 °C and for at least 3 months at room temperature. Hence, p62-E1-based ICTS is a rapid, accurate, and convenient method for rapid on-site detection of GETV antibodies. KEY POINTS: • We established a rapid antibody detection method that can monitor GETV infection • We developed colloidal gold test strips with high sensitivity and specificity • The development of colloidal gold test strips will aid in the field serologic detection of GETV.

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

Overview

  • This research focuses on developing a rapid, sensitive, and specific immunochromatographic strip test to detect antibodies against Getah virus (GETV) in animals, particularly pigs and horses.
  • The test aims to provide a practical solution for on-site screening and monitoring of GETV infections to aid in disease prevention and control.

Background

  • Getah virus (GETV) is a mosquito-borne alphavirus that is re-emerging and poses a significant pathogenic threat mainly to pigs and horses.
  • In regions like China, there are currently no vaccines or treatments available for GETV infections in swine populations.
  • Existing methods for detecting GETV antibodies, such as ELISA (Enzyme-Linked Immunosorbent Assay) and IFA (Immunofluorescence Assay), are accurate but:
    • Require specialized equipment and trained technicians.
    • Are time-consuming and costly.
    • Are difficult to implement in field or clinical settings for rapid diagnosis.

Objectives

  • To develop a simple, rapid, and cost-effective serological assay for the detection of GETV antibodies.
  • To create a test that can be used onsite, particularly in settings without advanced laboratory infrastructure.
  • To ensure the assay has high sensitivity and specificity, with no cross-reactivity to other porcine viruses.

Methodology

  • Utilized a recombinant version of the GETV p62-E1 protein expressed in eukaryotic cells, ensuring proper folding and antigenicity.
  • Conjugated the recombinant p62-E1 protein to colloidal gold particles to serve as the labeled antigen on immunochromatographic strips (ICTS).
  • Tested the ICTS strips against various clinical samples to evaluate:
    • Sensitivity for detecting GETV antibodies.
    • Specificity to ensure no cross-reactivity with antibodies from other common porcine viruses.
  • Evaluated compatibility by comparing results with established methods like IFA and ELISA.
  • Assessed the stability of the strips by storing them at 37°C for one month and at room temperature for at least three months.

Key Findings

  • The developed colloidal gold ICTS showed:
    • High sensitivity and specificity in detecting GETV antibodies.
    • No cross-reactivity with antibodies from other porcine viruses, indicating excellent specificity.
  • Results of the ICTS were consistent and highly compatible with traditional ELISA and IFA results.
  • The strips exhibited good stability, maintaining performance after storage at elevated temperatures and for several months at room temperature.
  • The assay provided results rapidly, making it ideal for point-of-care or field diagnostics.

Implications and Applications

  • The ICTS can be used for routine surveillance and monitoring of GETV infection in pig and horse populations.
  • Its rapid and simple operation allows veterinary practitioners or field workers to conduct testing without the need for sophisticated laboratory infrastructure.
  • The availability of this test will support early detection and aid in controlling the spread of GETV.
  • This technology could potentially be adapted or serve as a model for rapid detection assays for other emerging veterinary viral diseases.

Conclusion

  • The researchers successfully developed a colloidal gold immunochromatographic strip test based on the recombinant p62-E1 protein of GETV.
  • The test is fast, accurate, stable, and convenient, meeting the critical needs for on-site serological detection of GETV antibodies.
  • This assay represents an important advancement in GETV disease management with potential benefits for swine health and economic sustainability in affected regions.
