Global Infectious Diseases and One Health Conference

🦠 Pathogen–Host Interactions in GAS Infections

🎤 Keynote Speaker: Francis J Castellino

🔬 Presentation Title:
Molecular Crosstalk Between the Pathogen and Host in Group A Streptococcal Infections

At the Global Infectious Diseases & One Health Conference, Francis J Castellino presents a keynote exploring the complex interactions between pathogens and host systems in Group A Streptococcal (GAS) infections.

🧪 Research Overview

This keynote focuses on the molecular interplay between Streptococcus pyogenes and host biological systems, including hemostasis, fibrinolysis, and inflammation. It highlights how bacterial mechanisms exploit host pathways to enhance virulence and disease progression.

🔍 Key Insights

• Role of innate immunity in GAS infections
• Interaction between coagulation and inflammation pathways
• Plasminogen activation and bacterial dissemination
• Mechanisms driving severe infections like sepsis and necrotizing fasciitis
• Host-pathogen crosstalk influencing disease severity

🌱 Significance of the Study

Understanding pathogen–host interactions is essential for developing targeted therapies and improving clinical outcomes. This research provides valuable insights into how infections progress beyond mild conditions to severe systemic diseases.
