The Role of aDNA in Understanding the Coevolutionary Patterns of Human Sexually Transmitted Infections

Area of Science:

• Genomics
• Evolutionary Biology
• Infectious Diseases

Background:

• Phylogenetic analysis of pathogen genomes from clinical and historical samples enables global-scale studies of sexually transmitted infections (STIs).
• Deep sequencing of pathogen genomes provides insights into within-host and between-host evolutionary rates, genomic stability, and evolutionary responses.

Purpose of the Study:

• To examine three groups of pathogens transmitted sexually to understand ancient human behavior and pathogen history.
• To reconstruct the origins of current geographical distribution and diversity of clinical pathogen infections.
• To foresee potential environmentally induced pathogen evolutionary responses.

Main Methods:

• Analysis of deep-sequenced pathogen genomes from clinical and ancient samples.
• Phylogenetic analyses of sexually transmitted infections.
• Examination of pathogen genomic divergence and viral-host evolutionary histories.

Main Results:

• Insights into the diversity, distribution, and coevolutionary host relationships of STIs.
• Data on pathogen evolutionary rates, genomic stability, and responses to environmental factors.
• Reconstruction of ancient human behavior and pathogen evolutionary histories.

Conclusions:

• Combining ancient pathogen DNA research with modern clinical data is crucial.
• Equitable data sharing worldwide will benefit all researchers.
• Understanding pathogen evolution aids in disease prevention and predicting future responses.
