Background:

  • The Spike (S) protein of severe acute respiratory syndrome coronavirus (SARS-CoV) is crucial for cell entry and infection.
  • Understanding SARS-CoV's genetic makeup is vital for accurate diagnostics.

Purpose of the Study:

  • To develop a novel visualization method for SARS-CoV characteristics based on its S protein genome sequences.
  • To establish a unique genetic fingerprint for SARS-CoV for diagnostic applications.

Main Methods:

  • In-depth investigation of SARS-CoV S protein and receptor genome sequences.
  • Application of mathematical transformation and graphic approaches for data visualization.
  • Extensive comparison of numerous genome sequences to validate the uniqueness of the characteristic.

Main Results:

  • A novel method for visualizing SARS-CoV characteristics was developed, termed the "fingerprint map."
  • The revealed characteristic was proven unique to SARS-CoV through extensive comparative analysis.
  • The fingerprint map demonstrated clear visibility and reliability in a real-world case study in Guangdong, China.

Conclusions:

  • The proposed fingerprint map serves as a reliable and unique identifier for SARS-CoV.
  • This method can function as a complementary clinical tool for SARS-CoV detection, especially in ambiguous cases.
  • The findings support the use of genomic visualization for enhanced viral diagnostics.
