Principia aetiologica: taking causality beyond Koch's postulates

Area of Science:

• Microbiology and Epidemiology
• Infectious Disease Causality
• Biomedical Research Methodologies

Background:

• The Koch-Henle postulates, while foundational, have recognized deficiencies in establishing infectious disease causality.
• Current biomedical disciplines employ varied, overlapping methods to link pathogens with diseases.
• A definitive, universally accepted method for proving causality is still lacking.

Purpose of the Study:

• To propose a more inclusive and rigorous method for establishing causality between infectious agents and diseases.
• To introduce a novel framework that integrates contemporary scientific approaches.
• To define a new category of microorganisms, 'priobes,' crucial for disease causation.

Main Methods:

• The study proposes a four-assertion framework for causality: congruence, consistent biological response, progressive dissonance, and intervention curtailment.
• It introduces the concept of 'priobes' as sufficient and necessary causes of infectious diseases.
• The method emphasizes building an argument from a series of verifiable assertions.

Main Results:

• The proposed method offers a structured approach to causality, addressing limitations of older postulates.
• Identification of 'priobes' provides a specific classification for causative agents of infectious diseases.
• The framework allows for a comprehensive assessment of evidence linking agents to disease.

Conclusions:

• A new, inclusive method for proving infectious disease causality is presented, moving beyond traditional postulates.
• The concept of 'priobes' refines our understanding of microbial roles in pathogenesis.
• This approach enhances the rigor and clarity of establishing causal relationships in infectious diseases.
