Complete Coding Sequence of Western Equine Encephalitis Virus Strain Fleming, Isolated from a Human Case

Area of Science:

• Virology
• Genomics
• Public Health

Background:

• Western equine encephalitis virus (WEEV) is a significant arbovirus causing severe neurological disease in humans and equines.
• Understanding the genetic diversity and evolution of WEEV is crucial for disease surveillance and control.
• Historical WEEV strains provide valuable insights into the virus's past circulation and adaptation.

Purpose of the Study:

• To perform whole-genome sequencing of the WEEV Fleming strain, isolated from a human case in 1938.
• To provide a genomic resource for comparative analysis with contemporary WEEV strains.
• To contribute to the understanding of WEEV's evolutionary history.

Main Methods:

• Whole-genome sequencing of the WEEV Fleming strain.
• Bioinformatic analysis of the obtained genome sequence.
• Comparative genomics with other WEEV isolates.

Main Results:

• The complete coding genome sequence of the WEEV Fleming strain was successfully obtained.
• Phylogenetic analysis places the Fleming strain within the known WEEV genetic diversity.
• Identification of specific genetic markers potentially associated with virulence or host adaptation.

Conclusions:

• The genomic data of the WEEV Fleming strain provides a valuable historical reference point.
• This study enhances our understanding of WEEV evolution and genetic variation over time.
• Further research can utilize this data for improved WEEV diagnostics and vaccine development.
