Analyzing Macrophage Infection at the Organ Level

Area of Science:

• Microbiology
• Pathophysiology
• Infectious Disease Research

Background:

• Classical in vivo infection models often lack detailed physiological context, leading to speculative results.
• Reliance on colony-forming unit (CFU) enumeration alone overlooks crucial unseen physiological factors in infection progression.
• Understanding organ-specific pathophysiology is essential for accurate bacterial infection studies.

Purpose of the Study:

• To present detailed methodologies for two advanced infection models.
• To enable in-depth investigation of pathogen-host interactions within specific organs.
• To overcome limitations of traditional infection models and CFU enumeration.

Main Methods:

• Development and description of an ex vivo porcine liver and spleen coperfusion model.
• Utilization of a complementary murine infection model.
• Integration of diverse experimental outputs from both models for comprehensive analysis.

Main Results:

• The described models provide a framework for detailed analysis of bacterial infection.
• These models allow for the study of pathogen-host interactions at the cellular level within target organs.
• Experimental outputs can be combined for a more thorough understanding of infection dynamics.

Conclusions:

• The presented ex vivo and in vivo models offer enhanced approaches to studying bacterial infections.
• These models facilitate a deeper understanding of pathogen-host interactions beyond traditional methods.
• The integrated use of these models provides richer data for infection research.
