SARS-CoV-2 and Emerging Foodborne Pathogens: Intriguing Commonalities and Obvious Differences.

Area of Science:

• Microbiology
• Virology
• Epidemiology

Background:

• The COVID-19 pandemic, caused by SARS-CoV-2, highlights the global threat of emerging infectious agents.
• Foodborne pathogens like STEC share surprising similarities with SARS-CoV-2 in their evolution and pathogenesis.
• Comparative analysis of these distinct agents offers insights into pathogen emergence and adaptation.

Purpose of the Study:

• To compare the emergence, evolution, and pathogenic mechanisms of SARS-CoV-2 and STEC.
• To explore host-pathogen interactions and immune responses for both agents.
• To identify lessons learned from both outbreaks to inform future pandemic preparedness.

Main Methods:

• Comparative review of scientific literature on SARS-CoV-2 and STEC.
• Analysis of evolutionary trajectories, including point mutations and gene acquisition/loss.
• Examination of pathogenic mechanisms, receptor binding, and host adaptation strategies.

Main Results:

• Both SARS-CoV-2 and STEC evolved in animal hosts and utilize host cell receptors for infection.
• Mutation and gene exchange are key evolutionary drivers for both pathogens.
• Despite differences in transmission and scale, both pathogens exhibit multi-organ effects and challenge non-vaccine therapeutics.

Conclusions:

• Comparative analysis reveals convergent evolution and pathogenic strategies between viral and bacterial agents.
• Understanding shared mechanisms of emergence and adaptation is crucial for predicting and controlling future outbreaks.
• Lessons from SARS-CoV-2 and STEC can enhance global strategies for infectious disease surveillance and response.
